Thanks!

Totally!

Only for those who need to be recognized for doing something they are supposed to do. Just do it because it’s the right thing to do. If not for your neighbors walking bye.

Aint that the truth lol😂

Absolutely true! Lol

Don't do it for your wife. Do it for your property value.

Thanks for the kind words!

"Wanna-be movie credits". Excellent!!!

I appreciate that!

Did it work for you????

Yes! Please be sure to keep the rest of us posted....

@@lewisgeer1994my neighbor tried this by drilling three holes, it cracked the concrete to the edges after the foam went in. Worth a try I guess though

@@skeezix8156 Thank you for watching and commenting!

Since it's to high now- he's liable for Trips He did work so he can be sued

Or just use less

Thank you for sharing! I plan to have updates on how the concrete slabs have been holding up!

So I am curious how long it stays level

Probably not. That foam will break down eventually.

You get that stuff on your hands when it's wet you look like you've been digging around in a dirty butthole for about a week.

@@SuperSummit123 Hahaha! This is true. I learned that the hard way. It's a bitch trying to clean it off your hands.

LOL I don't believe they make a non expanding foam like this in a can! It wouldn't make any sense!

@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

@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!

Thanks for sharing!

did it hold up after a year?

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.

@@mikeygee4564 sure if it was bigger than a 3x3 slab. But this is just fixing sidewalk slabs, why go through all that labor and expense, plus you don't have to fiddle with finishing the surface of a new slab to match the rest. Have you worked concrete before? If you have and this is your suggestion then you must be a masochist. However, on a more positive note your suggestion WOULD add longer life to the section. (Edit: I have never had to struggle to level ANYTHING.)

@@mikeygee4564 you obviously don't work with concrete. Let's all sing it together Macho Macho macho man I want to be a macho Macho Man.

@@FarmerFpv nah you're right. I had enough sense to get educated and make a much better, and more lucrative, living with my noggin. I have worked concrete a decent amount for my own projects, and that's where my experience and input came from, and it sounds like I may have been wrong compared to you guys who slug gray mud for a living. My apologies, and I'll take your word for it. But it's still nice knowing I'm wrong and can pay an ass like you to do it for me for what I make in an hour. If you're nice, I'll by you beer and dinner too. I may even let you eat on the porch. (I kid, I kid - I'm not really this much of a pretentious dick, but it's fun poking at twats that surge on the simple thing they know, in an asshole manner). In all seriousness, I greatly respect your craft. I certainly can't do it as well as you.

@@JC-of2nm fair enough. I don't do it for a living so I'll take your word for it. IME, I've struggled quite a bit getting a slab level after all that work just getting it up (that's what she said). but cheers to ya for knowing what your doing and doing it well.

Lmao. all I thought the whole time

I was like how thick is that slab😂

I was cringing a little as all i could do was picture a water line or wire running underneath or something lol

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.

Mine is not where I could get a bar under.

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

@@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.

Never thought of that on tubs! Thanks bro I hate mudding tubs this sounds way quicker..👍

@@jeremyeaston3105 Just don't overdo it, and be sure to fill the tub with water.

@@theprophetez1357 I was a plumber 30 years, I started using it when I realized all the whirlpools we're being foamed. Your right way way nicer than concrete on this cheap fiberglass / acrylic tubs. Better on sound than mudding them too. On new construction you gotta fill the tubs for inspection, so I'd fill them then go around and foam them in, was a real time and mess saver. Barely costs more then setting in Crete as well.

@@TheAIRspace Yep I find it to have lots of advantages. You know I can't figure out why they call plumbers plumbers, or why they call carpenters carpenters. After all it is carpenters that have to keep things plumb, and plumbers sometimes cause damage that takes a carpenter to fix. So I think a name reversal is in order. 😃😁. Keep up the good work AIR space. 👍

@@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 :)

All of them.

Just 1.

Call the Amish, they'll roll in 100 deep and lift it by hand. And I ain't kidding.

@@jimmartin7881 that is no joke,,, best people ever

If you think prying works, go try it and come back and tell us about it.

@@troyc5994 my thought when that comment too. If you pry on a 100 sidewalks it might work on one of them.

If you hire a professional that using lifting foam designed specifically for this task, and NOT WINDOW/DOOR foam, it actually works very well.

@@tooz56 It's called pumpjacking. They use a polycrete compound not foam.

Just the tips? Lol

@@michaelbidwell4210 just the tip... Just the tip 🦙

And nothing but the tip, so help me God.

Thank you!

If you paid a legitimate company to pour a sidewalk and it sunk after they finished. You NEED to contact them and have them come back, rip it out, put a proper sub base down and pour a new sidewalk that's properly pitched away from your homes foundation

What size drill bit did you use?

I used a 1/4 x 12" carbide bit. A hammer drill worked best for me, picked up a cheap one for the purpose.

Thank you for sharing!

Is the driveway still level or did sink with the foam?

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

@@xthaking That foam breaks down and the sidewalk WILL sink back down , but he''ll figure that out the hard way

@@sneakyb8731 Is this what has happened to your concrete job? What material lasts longer than polyurethane?

I think I saw your video on YT about that. A porch walk way. I'd perhaps try this except the piece I need to level is a 4'x8' slab next to my pool and can only access one side. I'm barely down 1/2" in only one corner, so thinking this spray can method probably 2-3 cans max might do the job for me.

He needs an sds. Those are cringy for concrete 😂

@@durtygroove It is an SDS, he put it in a regular chuck.

Way too long of a bit for the job and he never appears to clean the hole with the bit as he's drilling. Smoked it.

@@jeffreywilmot3798 so he doesn't have an sds. Smh. You love to argue don't you?

@@durtygroove 0:30 sure looks like an SDS bit when it's laying on the sidewalk.

Thank you for watching and commenting!

You sure about that? Not being sarcastic. 1/2 inch is more than a hair. What do you guesstimate the compression will be in cubic numbers? I'm not doubting you. Just throw out some numbers.

Walking on it won't matter. Let's say the slab section is 4' x 5'. A 200-pound person standing in the center would exert less than 2 pounds per square foot on the soil below. Compared to the ~75 pounds per square foot of the concrete itself (assuming a 6-inch slab), that's just too small of an increase to matter. There might be other cases where loading would have an effect, but no worries regarding foot traffic. Loss of volume due to decreased "foamy-ness" over time might be an issue if the stuff degrades eventually, but that's a different issue.

Thank you for watching and commenting!

Thank you for watching and commenting!

It’s the same stuff

Doesn't it just sink back down after time? I would just dig around it and put dirt under it to make sure it stays level forever. Seems like extra cost and alot of work.

@@gr8t1bobo Im wondering about that as well....

@@gr8t1bobo it wouldn't sink back down unless the sub-base fails again. But you could do what you said you just wouldn't want to use dirt, you'd want to use gravel.

@Ebutuoy Skcus Just because that drill has a setting that says hammer, that doesn't make it a hammer drill. An sds drill would have work at least 3x faster, probably more.

@Ebutuoy Skcus since you obviously know nothing of the subject, i will educate you. The whole "hammer drill" feature on the drill in the video is a marketing ploy so that idiots like you think that they are getting a drill capable of drilling through dense material. That style of hammer drill is barely better than useless for drilling through concrete. The bit used on the video is not meant for said drill and i would be willing to bet that the bit was the only reason that drill did so well. The drill in the link is a true hammer drill hence the name roto hammer. In the future it will be you well to not speak out of turn.

@Ebutuoy Skcus you are silly if you think that i am remotely triggered.

What about $$$$$

@@tedhernandez8319 It was about $12-15 per sqft about a year and a half ago. That's for a renewal where we would try to lift it back into position. We have a stabilization option as well that's a good bit less money but we don't attempt recovery, simply fill the void and stabilize the slab/soil.

Had a resident spray the foam in a crack on rent house ,,ended up separating it 4 inches lol that was a fun fix

@@StragglerTx wow. I'm looking for the perfect project to test this out. Will upload my results

Loctite makes an expanding close cell foam

Yeah, I'd like to see it a few years from now after foot traffic and cold weather cycle (if theyre in a cold zone) Having the voids could cause frost heaving.

I think you'll find it's actually closed cell, not open.

If they aren’t separated how would they be uneven?

If you can lift a slab, Level & recompact, then replace, in 15 minutes, you lie.

Like any of us want to be moving around over 100lbs of cement block.

@@72Dexter72Manley72 There's a new tool called a "lever" so you can use a scrap pipe and a brick for a "Fulcrum" and life one end of the block, level dirt and lower block back down. I put in parentheses the two new words you never heard of so you can research how this complicated tool works!

@@mrdanger4851 Lol, You're the same person who can level the ground and tamp the dirt down underneath that concrete block "" In 15 minutes "". Lol How about doing all that in 15 minutes. And stop looking like the ass you are. Lol 🤦🏽‍♂️🤦🏽‍♂️🤦🏽‍♂️🤷🏾‍♂️.

Lol

The foam lifts the pad by expanding, it really has nothing to do with the can pressure

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

Those cans are not cheap plus he used the expanding foam there is filler foam too that doesn’t expand later. But in the end they can’t take the weight of repeated traffic and might slide off the slab if the soil is clay

Thank you for watching and commenting!

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!

there are companies that do pretty much this same thing. they just drill bigger holes and use a different method for the foam.

And charge lot’s of money.

@@Stackali and they use a special foam lol, not the home depot crap

It’s a special foam , the sidewalk will be like it was before in a year with spray foam

@@Hammerjockeyrepair it’s not a special foam, it’s just closed cell foam which is what is in this can.

I can’t. This tickled my soul 😂😆😂😆😂 .

You might be able to climb back down the column like a bean stock. Just leave the giant's possessions alone. 🤪

😂😂😂

You need the space for the filler.

Concrete is kinda heavy.

You know they sell shovels. Those blocks are so small he could've lifted them up and just put dirt underneath. SMH.

@@roberto3262 From 0:02-0:08 We can clearly see that after the first short walkway block, the next two blocks are much longer. I'll drill and use the spray foam any day for that project.

@@72Dexter72Manley72 then what? In a year or two you've got a ton of spray foam that's underneath them when the settle in deeper. You're not going to get more foam underneath the foam that's in there. That's for sure. Then you have to dig out foam and dirt next time. Yikes! Also, there's no stopping that foam on e it starts expanding. What do you do if it doesn't lifet enough. Same problem. Or if it lifts too much? Lifts higher than the next one that you're trying to match? Same problem. It doesn't seems very fail safe to me I guess.

Yes. After a week it would. It isnt true closed cell foam. Epic waste of time and money. A pry bar and 20 mins will do it.. ...

@@richardlangil5798 but what would you fill it with? Gravel, sand, or a concrete slurry?

Pry it up. Level the ground. Lay it back down.

Did it for my walkway with larger stones than that. Yse leverage and swing the stones to the side

100% sure it’s back to where it was
