What Happens when Your House or Business Begins to Physically Collapse (Journeys of the Mind)
Watch on YouTubeVideo summary
The video features an interview with Matthew Hos from Foundation Systems, a company dedicated to stabilizing homes across Hawaii by addressing complex geological challenges such as volcanic soil migration, hurricanes, and lava tubes. The core subject revolves around the critical importance of understanding how earth movement affects residential structures, particularly in regions where retaining walls fail or foundations settle due to shifting ground conditions. Matthew explains that their daily work involves assessing these specific problems caused by soil dynamics, which often manifest as cracks, leaning walls, or structural failures. He emphasizes that every project requires a unique approach because the geology of each location varies significantly, ranging from clay and silt to rocky volcanic terrain, necessitating close collaboration with geotechnical engineers who conduct deep soil borings to create accurate repair plans.
A significant portion of the discussion highlights advanced techniques used when standard repairs are insufficient, such as utilizing micropile technology and tieback anchors to suspend failing walls while new ones are installed underneath heavy loads. The interview provides a vivid example of removing an unstable wall beneath thousands of pounds of earth without causing collapse by using deep ground anchors and grade beams. Furthermore, the conversation addresses practical issues like filling volcanic voids created by old cesspools or lava tubes; this process involves detective work to locate underground arteries before injecting grout systematically from the bottom up to ensure complete fortification against water undermining. The dialogue also touches on material challenges, including how tariffs affect cement costs and the use of specialized hot-dip galvanized rebar designed to resist rust in Hawaii's humid environment, with fiberglass options available for areas requiring non-corrosive reinforcement.
Beyond technical solutions, Matthew offers crucial advice to homeowners regarding long-term maintenance and early detection of structural issues. He urges residents to inspect their homes annually by getting underneath post-and-pier foundations to monitor movement before it becomes severe, noting that cracks often follow the path of least resistance in grout lines or indicate rusting rebar expanding due to moisture exposure. The host draws a powerful analogy between foundation repair specialists and primary care physicians (PCPs), suggesting that while these professionals may deliver difficult news about necessary repairs and rising costs, their role is essential for preserving one's major investment—the home—for decades. Ultimately, the video concludes with an emphasis on proactive planning; homeowners are encouraged to address minor issues immediately rather than waiting them out, as deferred maintenance can lead to catastrophic failures where repair becomes impossible or prohibitively expensive later on.

Hello, this is Carl Arian, host of
Journeys of the Mind under that rubric
called Think Tech Hawaii. Today we are
lucky to have Matthew Hos Matt um who is
representing Foundation Systems and we
are exploring in some senses um the
environment of Hawaii and the um the the
earth itself [laughter] the soil the
aina as it were. So welcome Matt.
>> Hi Carl. Thank you very much.
>> Before we get started about Foundation
Systems tell us about your journey. I
mean you know how did you get working
there? you know, where did you come
from? Were you originally from Hawaii?
All that sort of stuff.
>> You know, I came into foundation systems
as um brand new to foundations to to
construction work. Uh I had uh worked in
many different arenas before this. Um
and you know what really drew me to it
was the fact that they have a mission to
make things stable for homeowners all
across the islands. And so, you know,
their
their connection to uh the local
population is immense. Uh they do great
work. Uh they can stand behind it and
they're great people to work with. So,
that's you know, that's what attracted
me to the whole thing and uh I'm very
very happy to be here and learning what
I have.
>> And I imagine, you know, every day it's
a different thing. So, tell us about
some of the projects you're working on.
And of course, it all deals with the
geology of Hawaii and you know, we have
hurricanes, we have volcanic soil, we
have holes in the ground that need to be
filled, you know, all these sort of
things. But what's your I mean, you
know, your your your the name of your
organization talks about foundations,
but so what do you do on a on a daily
basis?
>> On a daily basis, we have three
estimators here, and they go out to
houses all over Aahu, uh, especially um,
but to every island, you know, we
service every island in Hawaii. And uh
we look at various problems that people
present uh with their homes and a lot of
it is due to the movement of the soil or
migration of the soil and that's where
homes can experience settlement uh where
retaining walls can uh begin to fail uh
and that's in the form of cracks or in
leaning and so we assess those problems
and give them the best case scenario
best solutions uh and work kind of
within their goals for their home.
>> Okay. Because you probably have projects
ongoing. give us without giving names of
course uh give us a specific example of
you know a problem that you're facing
right now with a home in Hawaii and of
course the reason this is all so
important is our major investment for
most Americans unless you're
extraordinarily wealthy which is you
know very difficult these days unless
you
>> only a few of us yeah [laughter]
>> unless you invent something new on the
computer or something like or AI so give
us a good example
>> yeah you know I've got a I've got a
Great example. Uh if I am working on uh
in Kyua, I'm working on uh a home uh
that shares a wall. Uh the the folks in
the upper home uh have two walls on
their property, 9 ft and six feet high.
And then below that is an older wall uh
on which both of those walls were built
uh that is beginning to fail. Uh that
one's about 5t high. So the challenge is
the failing wall is underneath thousands
and thousands of pounds uh of of rock
and earth. And the challenge is how do
we how do we remove that wall, replace
it uh and and fortify it without you
know the rest of them falling on top of
us. So we had to devise a plan where
essentially we used our micropile
technology and tiebacks uh which I'll
explain in a second exactly what that
is.
uh using those to not only secure the
upper two walls um but then allow for
the careful removal of the wall below uh
in order to hold it essentially suspend
it uh you know over the earth while we
install the new one. So I mean that's
that's one of the more challenging ones
uh that we've seen uh in in recent time.
>> So how do you get a look underground
because you know you're not being able
to see stuff. So how what do you what
kind of devices do you use to to look at
the underground you know wall?
>> We as foundation repair uh contractors
are uh you know that we'll rely heavily
on geotechnical engineering for
something of that nature. That's a
highly complicated situation. uh we
essentially had to build um or you know
we're going to be retrofitting one of
the walls to suspend it which means we
have to not only do deep ground anchors
to hold it up but then uh you know then
we have to build what's called a grade
beam basically a large uh concrete beam
along the bottom so that it can you know
that can withstand uh all of the weight
while we work from underneath using
geotechnical engineering uh they go into
borings at various places on the
property uh go deep into the earth and
and test the soil. So, the composite of
the soil is really really important to
uh how deep we go with our anchors, how
many of them we use, you know, how many
pounds each of them will hold. You know,
when you're doing uh things in in clay
versus sil versus volcanic soil or um
things areas that are heavily boulder,
heavy and uh
and rocky, those are all different soil
types and they're all going to have
different bearing strength. What we have
to do is work with the geotechnical
engineer you know very closely uh to
monitor that uh so we can create the
right plan.
>> This is kind of analogous to medicine in
the sense that you know you guys are the
PCP you're the regular doctors and so do
you call in like geologists and say hey
what's going on with the soil uh and um
how does that work? the geotechnical
engineer does uh the majority of the
work on that. They'll come in, they'll
do the soil borings, they'll test it uh
and they'll give us uh basically a map
of exactly how the soil looks underneath
and that based on that they'll make
recommendations and that's how we then
bid the project.
>> Are there any times when the um soil
engineers come in and say, "Uh-oh, you
know, there's, you know, there's there's
there's so many problems here. You guys
are going to have to be careful or
perhaps you can't do anything." I mean,
are there any occasions like that?
>> No occasions where we can't do anything.
No. Um, in some cases, it's going to
take a it's going to be a little bit
beyond our scope. You know, whether it's
going to be heavy excavation or a large
rebuild, you know, something that we're
not specialized in, then we'll pass it
off. Um, but in most cases, you know, we
can make make a repair uh in in almost
all
>> Let me give you um an example that I see
here in Monoa um often. And you know
when I walked down Pey um which is not
not too far from our house. I walked
down the street and I at the end of the
Pey uh right below right above some
stairs uh there was a slide and that
slide damaged for some reason the the
[snorts] foundation of the house there.
Um so in that sort of a case what do you
guys do?
>> Well we have to assess exactly what
happened there. Can you tell me a little
bit more about the slide? It was a
rainslide. Uh, in other words, it was
caused by, you know, torrents of rain.
And then the, uh, you know, if you look,
you know, the house is supposed to be
like this, and the house started looking
like this. So, it was tilting. And so, I
imagine that was a a foundation problem.
And so, if you guys were called in, um,
what would you do? I mean, what would
what would be your kind of assessment
and, uh, what are the kind of questions
that you need to ask the homeowner
before you can do anything? We would
definitely give uh the house a good
look, but you know, from your
description, honestly, Carl, that's
something that we would uh call in a
general contractor to help with. In the
cases where the home is uh has pressure
on it, you know, from the hillside
beside it, it's um
like I had I had a similar one of these
situations where the hillside had
migrated over time and uh and begun to
press into the retaining wall, which
also was the back of the house. So the
retaining wall was sitting in the back.
The house was built directly in front of
it. It was, you know, that wall was also
a room. And what had happened uh was
that migration had begun to break apart
and and cause failures throughout the
CMU wall. Uh at that point, the only
option was uh for us to bring in heavy
heavy equipment, do a six-foot trench
behind it, uh remove that earth, remove
that wall, uh push it back, and you
know, put the put the wall upright
again. One thing people don't realize, I
think a lot of times, is that with
retaining walls, uh once they've leaned,
you can't push them back. You know,
there's no amount of pressure that we
can use to push, you know, an entire
mountain side back. So, you know, it's
important to watch for those things. Uh,
and I I want to go over things to look
out for, uh, you know, in your home when
it comes to the retaining walls and and
foundation. But in that specific case,
uh, you're looking at the house being
pushed, uh, by the earth. We would have
to get a general contractor in to figure
out whether whether we're rebuilding in
front of it, you know, or tearing out a
piece of the house from the behind or if
we can do some work to remove the wall
or remove the hillside, which typically
takes something called shockrete. Now
shockrete is um you know one of the more
extreme measures that we take in uh in
soil retention and that is basically a
system of um they call them soil nails
um but these are called tieback anchors.
They're drilled into the hillside at a
20° angle um and provide bearing
strength against uh the uh against the
hillside. First, we put down a large
wire mesh so that essentially that's the
cage holding everything in. Those
tieback anchors go down so that that
mesh never goes anywhere. And then on
top of that, we spray about 6 in of
4,000 PSI concrete.
>> Here's my question. So, you know,
concrete has to be shipped in to Hawaii.
And um you know, when uh Punoho school
was building their middle school, um for
a while there was some sort of strike,
long Sherman strike. So they weren't
getting the cement. So my question to
you is I don't know about strikes, but
did the tariffs affect affect cement
cost and where does your cement come
from?
>> I can't answer that question with uh
with specificity. It's more that I I do
know that tariffs have affected you know
all all building materials uh you know
one way or another we're affected by
that stuff. Um but uh I think that our
concrete has multiple sources. So you
know we we try to make sure we stay
ahead of the curve there. Um that we're
well equipped. you know, we bring it in
by the shipping container, you know, so
it's uh you know, so it's a pretty
extreme amount uh that we use on a
regular basis. Uh our company
specifically has uh four crews going
five days a week uh at various jobs. So
we finish off a few hundred jobs a year.
>> What does that mean in terms of your
reserve? I mean, if you're talking
about, you know, one one cement bag is a
pretty big bag, but I mean, do you have
like thousands in reserve? Is that what
you do? or you know cuz I mean it's just
you know I'm thinking about you know a
job like you just mentioned where you're
going to need a lot of cement.
>> It's not often that we have to provide
all of it when it's in such large
quantity. You know there are a lot of
other companies on the island that that
keep a far greater reserve than we
would. Uh and those would be the folks
that we call in in situations like shot
or whether we you know we have to do a
heavy pour. Uh mainly what we keep on
site is when we're doing small micro
piles um which only take a few bags of
concrete each. Let me ask you about that
still on the concrete issue. So if
tariffs r have caused you know a rise in
building materials is that passed on to
the consumer? Is that what happens? You
know in words if your bag of cement
let's just say one bag of cement is you
know $20 and um well how much is a bag
of cement? I I'll just ask you roughly
>> it can range. We use 95 pound bags uh
you know and so we get them at a at a
wholesale rate. Um, so retail, you know,
they're only about 50 bucks or so, uh,
you know, typically. But, uh,
when it comes to, yeah, just when it
comes to reserves, uh,
we just prepare for, you know, the the
jobs that we have ahead of us.
>> Let's say you have a 50 um $50 95 pound
bag of cement um, and then there are
tariffs put on it and so it goes up to
75. Who's paying that? I mean, in other
words, obviously you're paying it
upfront, but um uh do you pass it on to
the consumers? I mean, you must have to
do something like that.
>> Yeah, I think with any business, you
know, as building materials rise, you
know, that does, you know, affect the
end user. So, it does have to be passed
on to the customer. Uh you know, the
company can only shoulder so much and we
try to be as um as reasonable as
possible. Um but, you know, as as those
things arise, it affects everyone. Are
there other issues in terms of um uh I
mean do you have other big buys in terms
of um uh equipment like you must have
cement mixers and things like this? Are
these all entities that um you buy here
in Well, you probably don't buy them
here in Hawaii. They're probably shipped
in like everything else. Uh but do you
have a lot of um a lot of uh do you have
a lot of equipment with for your
organization? what we employ here at the
yard are are more uh customized, highly
specialized drilling equipment that we
use for our large jobs uh and you know
and down to small. One of the benefits
to working with foundation systems is
that we use mainly hand tools. So when
it comes to drilling, we can do that in
hard-to-reach places where we're not
going to have to knock down a wall,
bring in a gi giant excavator, uh and uh
and essentially tear up your yard on our
way to the back end where we might need
to do the repair. You're talking about
having people come out with with picks
and shovels, I assume. I'm using that as
kind of a metaphor. A
>> little bit more advanced than picks and
shovels, but yes, [laughter]
essentially, you know, things that can
fit into small spaces. Yes.
>> Like drills, for example.
>> Yeah. Is that what you're talking about?
>> Drills.
>> Yeah. Yeah.
>> Like those drills you see breaking up
cement on the road. Well, that's that
that's great.
>> I was I was going to say like the drills
we use for you.
>> There we go. So, let me let me ask you
also about walls um in general because
you know almost everyone in Hawaii has
sometimes they have rock walls. So, do
you help fill up rock walls also? I
mean, do you experience you must
experience rock walls? I know in Hawaii,
I mean, we have, for example, a rock
wall on both the back side of our house
or the front side of our house. Uh, do
you work with rock walls?
>> We work with all forms of walls. Uh, and
we specifically work on the repair of
those walls. Uh, it's an entirely
different operation to take one down and
rebuild it. Uh, so it's not typical that
we that we engage in that type of job.
uh that that takes large equipment, lots
of excavation, um you know, long
permitting process because you're really
moving around a lot of earth there. Uh
so when it comes to working on walls, we
work on CMU walls, this the uh the
concrete walls, uh poured in place walls
as well as uh as rock walls. Um and most
importantly what we what we deal with is
cracks and failures uh leaning uh or
especially in the rock wall sense we
find separation when it comes to uh the
settlement that they see. So when the
when the earth moves in those, you know,
in the kind of cobblestones that are,
you know, the lava rocks that are uh
making up that wall, you see separations
in the uh in the mortar there, that's
when you call us is because we can use
micropile technology in ground anchors
to help support where those are losing
ground either from undermining through
water um or just the natural soil
migration. and uh we can support that
and prevent them from continuing to drop
because as as you might know as the wall
begins to fail that allows earth to move
behind it. So if you're imagining the
wall is holding back earth moving this
direction uh the more that it begins to
teeter the couple inches comes from
somewhere and we don't want that to come
from under your house. if you have like
cracks in uh you know um you know
occasionally I'll be on our street and
some guy will come by and say hey can I
help you with your your rock wall I mean
if the rock wall has spaces between um
the rocks and there's is supposed to be
cement there could you just basically go
in and fill the spaces with cement or is
is it more complicated than that
>> you know in some cases it is but it one
of the things that is the detriment to
many homes here in Hawaii is long
deferred maintenance. You see a crack
and you see that crack every day and you
see that every crack every day for 3
years, 5 years, 10 years, 20 years. The
fact that it is not moved yet is not
necessarily an indicator of the future
there. So, one of the things I tell all
homeowners is when it comes to a house
that's on post and pier and you can get
underneath it, get under your house once
a year and take a look. take photos, you
know, get to know how your house is
moving so when something happens, you
know, when that change occurred. Uh, and
you can either tie it into something
like Konolo Storms, um, or you can just
say that it it seems like the house is
moving faster and faster these last few
years. I really should do something. But
now, to answer your question about the
Rock Wall guy coming around to to help
mortar, that's absolutely great. You
know, so many times I'll run into walls
that have deferred maintenance for 10
years plus. Like, oh yeah, that crack
has been there, you know, forever and
it's gone. Oh, it's gone an inch, now
it's two inches, now it's three inches.
You know, a lot of that stuff you can
prevent. And you can help monitor by
keeping up on your wall. So, if you see
that crack now and you can get it filled
in with mortar, that's great. Uh,
especially when you move into a new home
because now you have a timeline. say
since I put that in a year ago, if that
crack reupts, you've got settlement
issues. You've got movement that's
happening actively and that's when you
should give us a call.
>> Tell me about the cracks themselves. Not
in a um a rock wall, but in a regular
wall, there seems to be cracks. You
know, in you know what I've noticed
there when I look at the walls of our
neighbors or whatever or even our own,
there seem to be slight cracks, but they
seem to go kind of proportionally. And
uh there seems to be a proportion
uh proportionality to all this. And I
wanted to know, you know, what's what's
the deal here? Are are there just,
[laughter] you know, are there just like
certain segments of the wall that that
will show cracking? What's the deal?
>> Well, they can happen in two ways. uh
when you're talking about a CMU wall or
cement wall uh cement block wall um you
can have you can have one thing if it's
if it's going down the line like I know
the wall that you're talking about it's
um you know it's moving down the side of
the driveway and it's uh it's along a
hillside so it's going this way and the
hillside is moving down. So as as the
soil migrates that settlement can begin
to break in certain sections of the wall
and uh and that's where you might find
the cracks occurring. Now what you can
do is uh you know this is how you can be
your own detective in a way is you're
looking for settlement in uh in the wall
versus spalling cracks and I'll explain
what that is later but the uh the
settlement cracks will usually follow
the path of least resistance and that is
the grout line. So in your cement
blocks, if you see the cracks following
a stair,
if that pattern is occurring, then it's
usually the fact that it's starting to
break away from uh break away from the
wall in those sections just because
that's where the drop off in soil is.
When it comes to cracks that you see
running down the very center of the
block, you know, where where it kind of
it might migrate into the grout for a
little while, but then goes back to the
center and then out again, that is
typically a spawning crack. So, a long
time ago, uh, and now, we still use, uh,
rebar reinforcement in a lot of these,
uh, these concrete block walls. And in a
lot of cases,
those weren't necessarily
either engineered for or, um, or known
to withstand moisture for a long period
of time. So, one, if they are a
retaining wall, then they are are packed
against uh, earth for a long time. that
moisture then builds up against it and
it just starts to permeate the wall. In
other cases, if it's directly exposed to
the elements, uh like in so many times
I'll find that the concrete columns, you
know, they're supporting so many of the
houses here in Hawaii, the ones that are
on the ocean side, you know, or the ones
that are exposed to the elements, those
are the ones where I see cracks 12 feet
high, you know, the ones on the other,
you know, the back side of the house, uh
seem to be just fine. They were both
poured at the same time, but it just
means that that uh that exposure to the
elements is solid crack. So spalling is
when rebar is affected by moisture, it
begins to rust and then begins to
expand. Once it expands, it pops open
the blocks and that's where you start to
see those little hairline cracks. After
those hairline cracks emerge, obviously
more water can get in and the rebar
begins to expand faster. So when you see
those blocks completely broken off,
that's a huge failure. It means on the
inside and and you know I've seen this
across hundreds of homes now that it's
very likely that the rebar is dust. It's
no longer doing any work to help uh you
know retain the wall and uh and keep it
fortified. It is just now allowing tons
of moisture in. More failures are going
to occur and as the rebar continues to
start uh to expand and rust, it opens up
more to allow more moisture in and
expand those cracks. So, that's one of
those things for deferred maintenance
that is absolutely something to watch
for and uh and call us right away rather
than waiting until it's taken out your
entire column and I have to come replace
it.
>> The rebars are made of metal I assume.
Um you know, and you know, is there is
there in your experience is there a
better metal than um than you know I
mean you know is it is it iron? Is it
steel? Is it copper? What's a better I
mean what are the rebars made out of?
There's no better uh there's no better
option than steel, but what we use is uh
where is a hot dip galvanized oceanrated
rebar and that just means that we uh you
know we pay the extra for the coating to
make sure that it's uh going to
withstand as much of the elements as
humanly possible. Doesn't mean it's
going to last forever. You know rebar
tends to have you know a 15 20 year
lifespan sometimes better. um but when
exposed to the elements that's where it
lands and we might probably buy yourself
another five years all depending on how
expend you know how uh exposed it is to
those to those elements. Now one option
that's out there uh it's a little harder
to come by but they do fiberglass rebar
now and so for for areas that are you
know heavily uh withstanding water uh
those can be a good option. The only
difference is that that takes a little
bit more uh time and planning. Straight
fiberglass rebar is available uh right
away, but if for any reason I have to
use either, you know, an engineered cage
uh or I have to bend it, we've actually
got to order it that way uh because it
can't just be kind of bent on the spot,
you know, obviously it'll just break in
half. Well, you're giving me great
images of surfboards being in the middle
of walls, you know, with a fiberglass,
you know, which is, you know, when when
fiberglass came around as opposed to
boards, uh, with surfing, it was it was
a great invention. So, I, you know, this
this is this is great. So, let's say you
>> you caught me. We just cut them up and
throw them in the wall. Yeah, [laughter]
>> there I go. So, the surfboard walls. So,
you know, you go to let's see, you know,
I don't know if you've had any projects
on um the Big Island, but you know,
let's just say that it's it's also
occurring here in Aahu. Um that you have
a giant volcanic hole and uh I know you
have computer stuff that you could go
down part of the way, but sometimes
those holes, you know, you don't know
where they're going to they're going to
end. So, what do you do? I mean, what do
you do if there's a if there's a giant
hole that could affect perhaps it's
affecting the the foundation? Perhaps
it's not affecting the foundation. Um,
but because of our geology here, you
know, all uh geology based on volcanic
soil, um, if you have one of those
volcanic holes, um, you know, especially
that occur on the Big Island, what are
you what are you going to do? or holes
that for example are created by you know
um uh sewage systems in the past you
know um where they just used to pump the
the sewer into the land itself um that
that sort of thing.
>> Yeah. Uh there's there's a couple of
things uh there are certainly galities
when it comes to cesspools and uh you
know specifically if that's what we know
it is and the city has to be involved
with uh you know the proper removal or
or um or filling of that uh that area.
But what we tend to do if if we we know
there's a void um either we're doing
some detective work uh which is called a
probe and grout where we take a wide
swath of area uh that we know surrounds
uh where the void is and then we begin
to kind of try and locate uh you know
where the main uh artery of that uh
either that lava tube or uh that opening
really is uh so we can get in there and
and fill the holes. Um in other cases uh
a lot of times we see this we have a
large project um where we're doing an
airirst strip uh right now and that is
um that's completely undermined by water
and what we're having to do is go
systematically you know foot by foot uh
to fill in grout until we see return and
then we move on uh in order to fortify
uh you know the small amount underneath.
So it's a little bit of detective work.
If um you know if we can locate the void
then we try to determine what the size
of it is so we know how to fill you know
whether that's uh you know using buckets
of concrete you know that we that we mix
by hand as we go um you know using our
our drill system which we can inject
grout directly into uh the ground if
it's a small area or if we're getting a
cement truck involved uh you know to
figure out what we're doing there. But
it's a lot of detective work. Um there's
not a lot of of handy tools that we use
right off the bat. If it ends up being
something more complicated where there
needs to be um you know scopes and
drilling um then we call in the
geotechnical engineers and and so forth
to uh to do that really complicated
stuff so we get a great idea of what's
happening. I was really amazed uh seeing
your um you have kind of like a mini
cement mixer and uh could you describe
that to our audience because you know I
always think you know when you're
talking about you know you know
especially as a little boy I used to
love those cement trucks what we should
be turning and you know I don't think
any kid in America who sees a cement
truck a cement truck isn't really
interested but you have a kind of a mini
version of that. How does that work?
>> It's a simple it's called an Oberman.
It's a simple um cement pump. Uh so we
mix it in the vat uh and then it will uh
it will pump uh grout out through our
tools. And one of the ones we use mainly
is uh is one of our hand drills. And
that will essentially send uh grout
through the hollow bar that we use uh
and down into the hole uh outside, you
know, out the end of the drill bit. So
the drill bit that we use uh has uh has
holes in the bottom and then the bar
that we use uh it's called a hollow bar
system. But that steel bar is about two
inches in diameter and it gets uh gets
sent down with the bit and once we reach
the depth that we need to if we're
adding a microp pile per se uh then
we'll inject grout from the bottom up.
That way we're not you know we're not
pouring buckets over the top of a hole
where there might be uh you know small
small voids or or air pockets. Um, this
ensures that we get a a fill all the way
up from the bottom,
>> right? And you know, I know when that
when that fill comes up, you know that
it's it's it's it's solvent and stuff
like that. But there's a there like two
blades that I'm using my hands here, uh,
they that that people could break
cement, then you add water. It's kind of
an ingenious little instrument because
it it helps do what the big cement truck
does, but for a for a smaller thing. So,
Matt, we're nearing the end of our time
here. So what what kind of advice do you
give to homeowners because you know um
geology issues um are faced by almost
every home homeowner at one point or
another and it's because you know we
have so much underground water for
example in Monoa we have that volcanic
holes on the big island
>> um uh or volcanic voids as you pointed
out the word void I like it volcanic
voids and um so what kind of what kind
of um recommendations do you have for,
you know, our our general public in our
houses. And once again, you know, the
house is the major investment of most
people. So, and you're there to, you
know, be sort of the the the super
people to come in and help people. So,
what kind of recommendations would you
give to people? I think the one that I
said earlier, you know, one of the most
important things is uh is get under your
house. Go take a look. Uh get familiar
with how it looks right now so that you
can understand when there's movement,
when movement occurs, when cracks occur,
when failures in your wall occur. You
want to know about that as soon as
possible so you can take action. I have
so many times where, you know, the cost
of a of a project has doubled or tripled
or, you know, even worse, it's it's not
repairable now um or has failed
completely because someone decided that
right now was not the right time to make
their uh make their repair. At the very
least, you can get a sense of what it's
going to take to do it and then you can
plan effectively. you know, don't be
afraid of um you know, of the news I
might bring you, you know, for for what
the cost of the project is or, you know,
the uh the size of the project that we
have to do. Um but let's come up with a
plan. Uh the other thing is, uh watch
for failure points. So, if you have a
post and pure house, uh a lot of times,
first and foremost, you're going to see
that the the peers are sinking into the
ground. Uh you're going to notice that
water is now able to hit the termite
pans and rust those out. uh which will
allow, you know, little critters to
start eating away at your at the
underside of your house. Um you're
watching for floors uh to be off and uh
in their pitch. So, uh you know, if
they're dropping in certain areas or
windows and doors are beginning to stick
uh quite regularly throughout the year,
not just after rains, then you're
starting to have a problem. And it's,
you know, it's time to take action then
rather than than waiting it out. I think
when it comes to walls, you have to make
sure that you know the cracks are
something you address right away. They
will get bigger. Failures don't suddenly
sew themselves back up again. So if a
wall cracks, the walls crack will get
bigger. It's just going to be only a
matter of time or um a matter of a you
know major rain event, earthquake or or
any other thing that you know that God
might send down uh to you know to mess
with our lives. So, uh, this is
something where you take action early
and, you know, you'll find your way. And
then most importantly is think long
term. You know, think about the
situation that you are in your home.
Some people are trying to sell soon.
Some people want to pass things down to
their kids. And if you plan, uh, you
know, that you're going to stay in this
home for 20, 30 years. Consider microp
pile anchors. You know, these things are
really formidable. They go 25 ft into
the earth. We send a steel bar down and
create an underground column that's
pretty much immovable. You know, it's uh
it withstands thousands and thousands of
pounds of pressure. And if your home is
sliding, if your walls are beginning to
lean, these are exceptional ways uh you
know to extend the life of your home. I
mean, honestly, the one that's given you
so many memories what for 20, 30 years
now, uh you got to give it some love
back sometimes.
>> That brings up my last question to you,
Matt, today. And that is um there's a
psychology here and you know when you go
into a home situation and you're a
pretty mildmannered guy I would say a
very mildmannered guy and you go in and
you give people the news and then you
give a price tag on top of that and a
price tag that may be continuing as you
do their project. how you know what what
are people's reactions and and you know
how do you how do you deal with those
reactions in a uh mild manner way
because you represent of course uh
Foundation Systems and you're you're
trying to do the best that you can but
you know it's you're a baron you're
you're a harbinger of of of of bad news
so how do you deal with that you know
not all the time sometimes I'd say you
know what you're good don't worry about
that thing but uh yes I know it's um
it's not necessarily dealing with it is
it is the approach that we are here to
help. You know, first and foremost, you
called us, we didn't call you. You know,
we are here to help for the problem that
you brought us out for. Uh, you know, we
try to address that first and foremost.
And then, uh, you know, we we play a lot
of detective work, like I said. So, I
will I, you know, kind of make a
diagnosis of what's going on at the
house. Then I'll say, you know, why
don't we take a full walk around and see
what might be causing this issue and see
if we can do some preventive measures.
And then we talk that out. So I can say,
"Here's what we would do to fix
everything, but maybe here's what it
would do to fix the thing that you're
most worried about right now." You know,
and based on where your budget lies,
based on, you know, your home situation,
whether you're going to stay in a house
longterm or short term, um, you know, we
can devise a plan that works uh, for
most every situation. Uh, and one of the
things is we're very honest with with
what's going on. So, if you have a giant
crack in your floor and it's uh it's
breaking off like a cracker and your and
your house is, you know, tilting in a in
a way that needs to be handled, then I'm
sorry, but I have, you know, this is the
baseline of what you must do uh in order
to fix that thing. So, well, let's work
out the, you know, the details from
there. But I think that, you know, we we
take an approach of fix the thing that's
most important now. uh here's what you
can do preventatively if you're ready
for it and let's decide what the next uh
you know order of business is what's
your path
>> we will conclude on that note that was a
wonderful way to end uh Matt and you
know I I'm going to use that metaphor
that I used before you really are the
house doctors I mean you come in and you
you're the PCP and you say to your
patient uh or you say to your client hey
this is what you got to do and uh uh the
only bad part about this I think for the
client is that you know this raises
expenses, but as you said, you know,
better to do it, you know, it's sort of
like you're you're you're the doctor
advising and saying, "Well, you need to
walk more, you know, or you need to you
need to exercise more, you know, and
this is, you know, if you do this,
you're going to last a lot longer." So,
I like that. Thank you, Matt, for your
uh really words of wisdom for all of us
here in Hawaii where we spend, you know,
a lot of our time in our houses and this
is our major investment. So this is uh
uh Carl Aki, host of Journeys of the
Mind under the broader rubric of Think
Tech Hawaii. Aloha Matt and thank you
Carl. Thank you very much.
