Lifting a sunken concrete slab

so for this project I raised a broken concrete sidewalk with a jack and expanding foam
An uneven sidewalk not only looks bad, but it creates a tripping hazard. If the concrete slab is still intact, don't waste your money on replacing the concrete. You can raise your sunken sidewalk with this technique.

Why not remove the old concrete, re-level the ground and pour a new section?
cost
That turned out pretty good. I’ve seen both the foam or mud injections used to lift driveway pads.
Worked well
Never seen that done before. It worked out well. Thanks for sharing. I may have to use this method some time.
it worked great, could have hooked the sides with something instead of anchoring chain to top if I had bigger hooks.
John !!! looks like another quality job 👍🏻
Thanks 👍
Good job!
Nice job ..looks very cool John..
Thanks 👍
Thanks for sharing 👍Good job 👏
Thank you! Cheers!
Great work bro. Nice
Thanks ✌️
Great job Procut 👍🙏👍🙏
Thank you 🙌
Good job, thanks
No problem 👍
I don't know that I would do it this way the next time, but it did work.
Great video. Cool to see.
Thanks!
Good thinking, John... If you are going to do something, might as well do it well. I am sure your customer will be very happy with the results... Thanks for sharing... be well....
I hope so too
good job
Thanks
I never seen a slab raised with a jack an then use that foam for support before. That will be great if it lasts for years and years, I have always seen other thick curing fluids pumped in to actually raise the slab up.👍🏻
shouldn't go anywhere.
@@TheProCut17 How is it holding up after a year?
@@bones6554 settled a bit after install, but holding up well
If you could have left a couple voids to then fill with concrete maybe ? A great idea for sure 👍
I will get back out there for another lift, maybe drill a couple core holes and grout fill them
THAT GREAT STUFF IS GREAT!!!
yes it is
I am amazed that the floor jack was still on the piece of concrete you trying to raise... maybe htat was intentional ? Intentional to make it swing up ? really surprised those tapcons held too. I would be the secure set would actually lift this pad, no 4 by 6, no jack, just high temperature, and time.
tapcons are very impressive
Good way to lift and hold it. Maybe clean off the organic debris before sealing cracks and holes next time though.
I just blew them out/off, what would you have cleaned them with?
Moisture speeds up the cure of the poly foam.
As bad as that slab was the better option was too replace it. Then a better bed that can support the new slab would outlast the foam trick.
I agree with you, replacing it would have been the best solution. I just wanted to try this and it was much more cost effective at this time.
great stuff is not close cell foam which means it will suck in water become softer and not last very long, use close cell foam will be much better off.
can a DIYer get closed cell in a can? I try to keep my stuff easy for someone to recreate. I'm open to learning better ways and products.

SecureSet is also available online.
Sika has a closed cell (hydrophobic) canned product. Sika Boom 20 oz. Polyurethane Foam System (not specifically for lifting the slab, but if you're doing the lifting, it should be better than GreatStuff for dealing with moisture, etc.
Since the block below it isn't much better (looked bad), IDK I would have just repoured both blocks IMO. Too much damage. Thx for recording.
re-pour wasn't in their budget. this is still holding up as of right now
Temperature and humidity is very important for how that stuff cure
it was a test after I saw a few videos, I wouldn't do it like this again. I would jack it up and fill under with concrete
How many cans did you need to use bro? Love your channel.
If I remember correctly, I used about a half a dozen or so. Just buy a case. Use what you need and return the rest. That’s the best way to do it. That’s what I did.
I've been looking into this for a section on my driveway, way at the top where I dont drive or park. I need more than a few cans. So far it looks like Secure Set may be the strongest DIY product I've found.
Its specifications are "This is a 4 lb. density foam, 10 cu. ft. kit, with 70 psi compressive strength, and a load bearing capacity of 10,080 lbs. per sq. ft.".
sounds like you will get it done after putting in your research on materials
I did secure set - but the second product - it took the whole kit. I am happy with it. Drilling holes, for me took FOREVER.
@@DanTheManIOMyou need to use a hammer drill next time. Regular drills are terrible for concrete
Interesting!! How does someone Comment on this great video?
I know, right?
Im thinking of drilling a hole and pouring self leveling concrete in.
should work, add a piece of rebar in with it too
I need to do this same thing and need more info on the Tapcon screws / bolts. What did you use on size bolt. I have the hammer drill . My only concern is attaching the chain to the sidewalk. What do I need. I know the Tapcons are expensive and are they reusable as I have quite a few sidewalk against the house with a sloping issue.
I used a 3/8 x 4" tap con only $10-15 for a 10 pack. yes they are reusable. some one in the comments mentioned that great stuff is open cell foam and using a closed cell foam would be better, but didn't give a brand that is closed cell.
@@TheProCut17 Thank you.
I’m a little surprised that those Tapcons didn’t pull out.
tapcons are awesome, I don't know how we lived without them for so long
@@TheProCut17 Did you drill pilot holes, or do they go straight in?
yes you have to pre-drill for the tap cons @@tchrapko
How did you know how many cans of foam to use?
just a guess
and kept adding foam until I felt the entire cavity was full
amount will vary depending on situation
How long does the foam last before it sinks back down?
It’s been holding up a few years now
It'll last a few years.... Till the foam starts breaking down. There is a more proper foam for such tasks. Cool job, and I mean, it's done.... But you gotta think about the longevity of materials used in projects like this.
I went by it last week it had settled a bit, I'm gonna get back over there dig the side out and pour concrete in there instead.
@@TheProCut17 would be good to know how this concluded
@@mixedupmenopausaladhd3999 haven't been back out yet. but I've had no complaints from my friend.
How long does the foam last?
only time will tell, but it's still holding strong as of right now
how many cans of foam did you use? i have a pad in front of a entry garage door that needs the samething
I think it was 6 or so, been a while I don't remember exact number. just buy a bunch and return what you don't use. that's what I did
thx
How much should I look to pay if I get someone out to do this for me?
2-3 hundred
Cuanto tiempo dura ese trabajo?
It’s been holding up for now, only time will tell
Nice job. But I noticed you made a decent amount of grind marks. I suggest next time getting C clamps as your lift so that way you avoid all that. But otherwise nice job.
no grinding just the rain that made the dust from drilling the holes look like that
this one is on 12 of 936 my phone kept pausing
this video has been a good earner lately, sometimes they take a while to take off

Just in the ads
Nice job! I was just thinking to myself. Hope he isn’t going to leave those holes in the slab. 4 ads
lol holy slab

Got one showing how to raise a sunken concrete porch with 4 columns supporting a roof?
This is too easy.
I wouldn't recommend foam for that, you'd need more structure
@@TheProCut17 Got one you've recorded doing sunken concrete porch was the question?
My first time seeing this. So what do you do underneath? Do you go in from the side and add more concrete? You would think it would fall again
the foam fills the void
@@TheProCut17 so are you saying you’re going to put more foam underneath? Or just the original foam you put down already?
@@TheProCut17 gotcha
I put 10 cans on there 🤣
@@TheProCut17 lol that’s the part you didn’t show
Looks like you cracked the shit out of it
It was already cracked and sunk I did not do it
Folks do not do this hack especially in northern states. It's crap.
holding up well in east TN as of right now, time will tell
What a waist of time and money! This sh…t doesn’t work! Less than a week start failing! Big No!!!!!!!
been two years still holding, sorry to disappoint
Let’s see it a year or so later. I’m sure it failed. Call a company that does it for real and warranties the work like A1 Concrete Leveling.
still holding up as of right now
I’m surprised. It would never hold on Colorado. The domains soft and breaks down with our weather. Ants and termites love to love into. Time and date stamped picture would be cool to see with like a news paper date.
They use the same thing to lift overpasses that are sinking 🤷♂️
Just on a larger scale
good job
this has been a good earner over the last few months
