Different foams for a different amount of lift. Blue can for minimal Black can for large. Red can for in between. Also the amount of moisture in the ground affects cure.. Foam if enough used and cured should hold up. Some plumbers use foam under fiberglass bathtubs . If it looks like you over filled, put a piece of plywood across the joint with added weight. Will keep it from going too high.

I hate to break it to everyone but that type of foam will crush over time and the slab will fall again, you need to use foam that has a lbs designation, I used a 5 lbs foam to shore up a soft wooden plywood deck to prevent having to tear it out, but you would need to find a way to inject it. You can hit it with hammer as hard as you want and it won't really do anything to it. If you hit cured spray foam with a hammer it will crush.

[@cthunter41]

@bradcliff7099 yes they do. They make a very low expanding foam for windows and doors so it doesn't bind the jam up and lock em in place. There's high expanding, landscape for ponds, fire retardedant, bug retardedant, big gap filler. There's lots buddy, i so this shit for a living. If you get the shit the windows it won't expand at all under pressure must be in atmosphere pressure to expand what little it does

[@bradcliff7099]

@cthunter41 Yeah ok I see where you got me on this, but seriously if anyone goes and buys the very low expanding kind, when they know exactly what they are attempting to lift, says to me they don't understand what the different degrees of expansion can do or will do, they really have no business taking on something like this. I'm a truck driver of 30 years and no good at electrical wiring, so I leave it to the electricians. Really my comment was mainly in humor as in I was getting at its kind of common knowledge when buying a can of this that there is an expectation of expansion. No harm no fouls!

[@kenreynolds1000]

Just saying.... A 6 foot pry bar under the slab would lift it better so your foam would expand to fill the gap instead of squirting out. a couple of rocks to act as fulcrums and wedges to help with twist as well

[@chrisparker4940]

Exactly!! You stole my reply.

Not really, the foam is acting under pressure therefore distribution the overall Youngs Modulus creating a uniform pressure. This will last much longer lifting with a crow bar.

This is stupid take a block of wood like you said a big pry bar and some dirt but also you have to look at the condition that's not cracked

[@SuzukiKid400]

@@Hitngan I 100% agree. As the foam starts to lift the slab, it opens up free space underneath the entire slab which more foam rushes in to fill. It’s actually quite genius how this works and in the end, the force distribution is absolutely perfect, far better than even tamping a layer of gravel would provide because you would NEVER get the compaction of the underlying material and the flatness to perfectly match up with the flatness of the slab. This is quite brilliant.

[@mackendw]

the method I used was to build a jig out of wood and put a single lift point hole in the lower slab and use a car jack to lift the slab up to level ...then drill 7-8 holes and fill with low expansion foam to fill the void. that way it won't lift it up too much but still fill the void.

[@JC-of2nm]

Alternatively, 2 pry bars, 1 flat shovel, a bag of sand, & a bag of gravel. (Edit: some sort of blocking [2] for leverage) But this is definitely some big brain thinking, foam is amazingly versatile in application. I have used it as a seal

[@mikeygee4564]

No way, seriously? It'd be so much easier just to bust it up and lay a new slab than do that. You'd have to lift the whole damn thing up just to get the gravel and sand underneath it, and then struggle getting at level again. That's ridiculous.

A 'small' amount of the DRY MIX, dusting the pan, to prevent sticking... IN this case.. LEAVE THE CONCRETE DUST, in place, anywhere the foam 'may' touch the concrete. Why? To prevent 'sticking' and for EASY clean up, once dried. "Should", come right up.. and then, allow for however you wish to clean further. My opinion. Works the same way on siding. The foam, will adhere to the grime / dust / dirt / mold / mildew, and NOT your siding, IF you don't clean it 1st. In my experience.

@@theprophetez1357 well 7 ruptured discs later, Im out of that whole plumbing gig, but its all good. I paint stuff for people create art and make youtube videos about art now. And dabble in building science and remodel my own place slowly but surely. Personally Instead of using canned foam, id get a closed cell Kit (for less money overall) for raising a slab like this gentleman did. There is valid concerns about the open cell trapping water and heaving from frost as mentioned. But on a tub the cans are awesome, and I used TONS of the fireblock foam after it came out where I was doing apartment fire restoration work for a few years. As for causing damage. We used to say the only thing worse than termites for your house are plumbers electricians and hvac techs :) Cause a bad one can cut up a lot of stuff that don't need to be :)

[@wh4860]

You had the money to buy a case of spray foam but didn’t have a level?

[@tonykari5124]

Pretty cool. How long will it last though ? Especially in winter?

[@the70splinter]

I think ya got a long enough bit... what, ya drillin to china?? 🤣🤣

[@percival23]

A sidewalk that dirty should be sent farther down from my eyes ...not up.

[@michaelgonzalez5377]

WOW OUTSTANDING VIDEO. This is truly genius 👏, thank you for the great advice that I will use in the future. OUTSTANDING.

[@SoundScientist1]

Why don't you simply LIFT the lower concrete pavers (using pry bars). Then put some aggregate (small gravel or pebbles) underneath, & re-seat the pavers? This seems overly technical (deploying the hammer drill & all that)...

[@battles151]

Just because it's a unique way..doesn't mean it's the easiest nor best 🤫🤣 Boys, don't try this while.your mothers back is turned

[@w426a]

6 cans x $4 = $24 cost, assuming drill and bit were already there. Versus $300-500 for a company to do the work, if no slabs removed and reported.

[@tinahuntington2406]

I have a 4' long pool walk that is faced with pool edge coping and the Pro's wanted $2700 to lift it 1/2" to line coping back up on adjacent slabs and coping. I will try this instead!

[@speed3000gt]

I thought the foam keeps expanding as it dries... do you have an updated picture or video to show how level it is now after curing? Did it raise too high? Thanks for sharing the video, I'm going to try it

[@friendnfamily9053]

Hi, thank you for asking. It did raise 0.5-1" higher than expected. Should use less than 4 cans of foam, instead. Will do a follow-up video on this soon.

[@LessThanHandy]

@@friendnfamily9053 Can't wait for that follow up video. Really enjoyed this one for we sure have plenty of u leveling ourselves...

[@chevman46]

Would ot be better to block it up first then foam ...?

[@jimjordan5630]

@@chevman46 Maybe that would be like lifting you car up with a large pry bar and then putting the jack under it? That's the purpose of the foam, to lift the slab (which is usually very heavy) and while lifting the slab, the foam is also compressed giving support under the slab. If you lift it first, then by the time the foam expands, it will seriously raise the slab even higher. IMHO JS

[@cincinnatiking8008]

It looks like you made the same mistake I did with the drill bit. That's an SDS bit. It's for an SDS hammer drill. It looks like you have a regular hammer drill. That's why your bit is wobbly, but it seemed to work.

[@thecloneguyz]

THAT STUFF IS GARBAGE ITS FOR BLOCKING AIR They actually sell expansion foam that's load-bearing I don't know why you didn't figure this out or buy that stuff instead it was probably in the same aisle - literally probably right next to that garbage

[@mstrpth287]

Is it garbage if it works? Im sure high expansion foam cost way more

[@thecloneguyz]

@@mstrpth287 they sell it in the same places that stuff dude he just didn't read the back of the can

[@2loco]

@@mstrpth287 it may have worked at the time of filming but once exposed to the weather, time and weight, it'll probably compress and sag and the problem would reoccur. They have structural foam for this purpose, not just for shits and giggles.

[@friendnfamily9053]

@@2loco Thank you for watching and commenting! Stay tuned for follow-up videos on how the concrete slabs have been holding up!

I would probably do this and blow it all out the side, going to give it a shot anyway. Thanks for sharing.

[@cabbagehead4706]

Great idea but use some leverage(crowbar) to help it hit flush out with the higher one A little piece of grit or what have you will stop the foam from raising it

[@SoCalDad]

All I see is a mess. ...my question is, what are the environmental consequences of having this foam in the ground. If it rains, will the chemicals from the foam eventually seep into the ground?

[@The_Conqueeftador]

Or ya know. A crobar and a bag of sand.

[@coolhluke8089]

Oops too much. Gotta do the other one. Damn, not again. Got it! But my sidewalk it 2 ft takk

[@alpagano50]

Dig a hole on each side about the size of coffee can, Insert a 2x4 under block and use a 2x4 on grass and lift slab, after you lift it insert foam from sides to support. now you can control the lift . works for sidewalks not large slabs of a driveway.

[@nesco713]

Neighbor just paid 2400 to have a few slabs fixed.i think this would have helped
