Lifting Sunken Concrete Driveway Pads

[Music] well I finish pressure washing the driveway and it looks great I just hope this sunken pad and the cracks can be repaired matvey foundation repair is going to lift this sunken concrete driveway pad so it meets the level of the next pad that way we won't trip on it and it will last many years afterwards [Music] Jack I put under this 12 ton jack easy to buy clothes [Music] without too much stress then we'll just lift it all the way up and fill it [Music] is this typical the thickness of the pad um it's a little thin I think but it's pretty normal I mean a lot of slabs aren't more than three inches thick this looks a little bit under three inches to me [Music] so most driveways are like three inches but three to six inches is is what I use well I guess so for lifting it's easier [Music] that's what I want to watch [Music] and then the rest of this little that's gotta come up a little bit more okay we'll just slip that that distance with the GU that was almost too easy Oh raise that one broken section up here a little bit in process a special bit for this is carbide or diamond or is a diamond diamond that is a so expensive it's crazy I do not get them for myself my boss gets them [Music] [Music] oh this is the the goopy ins key you inject in there okay two to four feet I get it travel down a mole hole into interesting [Music] so the goop they inject here is poisonous to mammals or anything chews it up which in our case would be good we'd love to get rid of the moles that way [Music] so I usually start injection about 90 degrees and then it'll continue to heat up to a hundred 105 it makes and now or does it as it's injected it's mixed with as as it's injected the two different materials come through two hoses and in the gun they're mixed together and then they react thank you one of them expands and the other one hardens these little orange things are disposable like this one will probably be used for most of these I might use another one if we used to have ones that were bigger and you tap them in like a nail each one of these would have an individual one and those would last her Part A and B are going into simultaneous simultaneously and I'll start to feel this lift will be able to tell when this is no longer when it's this loose yeah and my guess is we've created an enough space that it'll probably come out the side [Music] Wow you can I cut it off with the saws I brush it down [Music] and I'll do a four more injections make sure it's a hold after I take it off [Music] how far that's a spread yeah I can see all the way to the other pad second pad whoops [Music] so we can park our RV on this when this is all done yep yep yep give it like 20-30 minutes and you should be bye hope coming up it's almost too much we already you know yeah that looks pretty good this is basically filling and the way we can tell us when I pulled this back out the foam should come right back up through the top and it's bull can you feel a little bit of back pressure as you yeah a little bit you get the idea I do you put a little too much in that allure yeah there's the art to this too all feel feel it with your hands but then another thing you do is tap on this get this to go down a little bit a lot of the time the little rock in it is pushing creating friction so that it won't actually go down unless you give it usually I get a either a hammer a rubber hammer or I get my my partner with a pry bar and a piece of wood tapping on it and it'll go right down well it doesn't actually go down this this allows this to come up then right and but it is up [Music] that means it can lift it just slightly oh there we go yeah as you see if it's alive the diffuser this are bad when you're in the closed space this one I'm not gonna inject it's already up against here I don't want to delicious all I'll leave that one alone do you think it has sunken since it was poured it relative to the garage yeah this is definitely sunk but I think it's something okay it wasn't that much it was only like what three quarters of an inch maybe but for 40 years that's pretty good right now very slowly but it is lifting and rather than lift it and create an edge there I'm just gonna stop a lot of space under this near the garage okay which also adds to my theory that things just 70 this was probably uptight against here yeah so that's probably about how much it's um so we've been around up here for 10-12 years [Music] he started out I think with like 10 employees and we're at 70 now our two most common things are the first one is water damage that is the most common but after that it is new construction or old construction where the soil was not compacted well based on the way the slab behaves and based on the way it's cracked no rebar ochio rebar most most people do not have rebar surprisingly but it is incredible how much strength it adds to your to your slab it's kind of odd because this is cracked here and this is almost too high and is this is almost too low it's like oh I'm gonna cut the difference between the two this stuff goes out as you could see over there how far it goes out and it'll go up inside this crack and almost act like a glue there it is right there you get the idea right on cue almost like the Elizabeth to me these bubbles indicate water yeah so there's probably that empty space is full of a little bit of water after the rain which over time that would erode this out more and more but with this it now there's no space for the water to sit in there and this will not wash away with the water a little bit of lifting of the second pad here so soup is doing the lifting ball on here [Music] and what do you think I can lift him or sir this is kind of up to you if you want now I'd say it looks pretty good to me yeah okay that's fine like here I'm gonna lift this just the tiniest bit and it'll probably make this pretty darn evening all right that's the fault it's a little hard to tell on the video but what a huge difference I'll be able to fill in those cracks now with some good quality and add some sand to it to make it match as close as possible to concrete next step is to clean up the material it squirted out in the places [Music] you knocking down some of the sharp edges this material will turn yellow over time from UV light but you can brush it up with a wire brush or use brake cleaner [Music] he's picking up Christmas oil back under the area here he lifts it up okay brake cleaner yeah it's a great cleaner okay we found you can use any but we like Oh Riley's best so okay just a little bit of concrete dust I sifted it out with the calendar just regular high strength concrete okay you just fill the whole fine whatever size of rock you want this is pretty small here so I'll have to use like that and then just sprinkle it on there down and then I usually do just a tap a wander over it as it helps blend it in a little bit as you can see [Music] I was told to let it dry for a day before washing off that little bit of residue that way the patches will have a chance to get nice and hard where does dry weather I will the cracks

“13 mins? No way am I going to watch all that”

13 minutes later: “Well that was interesting”.

That technician was a good sport, probably didnt expect to be recorded the whole time when he showed up to the job. He's clearly knowledgable and passionate about his job.

My dad a contractor for 30 some years used to say "you can watch me do a job, but questions cost extra".

His reasoning is, it takes longer to discuss what you're doing vs just being focused and getting it done quickly.

I wonder if they can do this to the entire city of Houston.

[u/Wowbringer]

That's a hell of a front lawn

[u/xlude22x]

I hope that guys manager saw this. An employee like that deserves a raise if not moved to a higher position.

[u/yun999]

Amazing first time seeing something like this

[u/TheInvincibleMan]

Legit, this is the weirdest thing that reddit has done to me. I was researching ways to lift precast concrete on YouTube last week. Stumbled on this video and here it now is on the front page. Dayum.

The worst is when your shoveling snow and you CLANK right up against the slab in front of you because you were on a sunken slab. Send a shock down your arms.
