This video has everything of a real DIY project - needing twice as much as you anticipated, taking twice as long, the "wrong" thing moved first, and using a vehicle in a way it was not intended. :) Glad you showed everything and not just some "ideal" project.

I was quite disappointed to open my kit and not find a red shirt/blue jean private mentor included. Another classic case of Expectation vs. Reality. I attempted this on a simple 2 inch 20 foot sidewalk raise. I ended up with approximately 1.5 cubic foot on my clothes and on the equipment. 2.5 to 3 cubic feet expanded onto the surface. I accomplished raising one edge about 1/4 inch. What a mess. Thank goodness for Acetone. If you guys ever travel to San Antonio please stop by and show me how easy it should've been.

Thank you for showing the entire process, really helpful. I would suggest wearing safety glasses anytime using the spray gun, it's so important to protect your eyes.

Some questions came to mind in the process that wssnt clearly explained: 1) why more than one nozzle? Was a new one used for each hole? Or just after returning after extended drying time? 2) how to determine how much tape wrapped on nozzle to prep it?? Is that to seal the size of hole while applying/filling w sealer. ? 3) how to know when to stop dispensing each hole? At each application layer? 4) how do you avoid lifting too much? Doesn't it keep expanding after you stop filling? 5) prepping the nozzle , to clean/vacate it between applications of foam. Couldnt see what you did. Did you Empty hose of the foam, remove tip and then cap with a new clean tip? 6) what was the plug removed between holes? Was it the nozzle hardening quickly or a plug from the hole? 7) why spray foam into box before filling the hole? Was the line filled with air? 8) what if there is an unknown big gap under the 12x12' slab further down the driveway? Maybe that is where the extra foam was going? 9) what does "hear air coming out of crack" indicate? 10) did the 1/4 inch raise on garage side come back down later after putting the car on it? Or did pivoting primary slab level it after infusing more foam in holes? 11) would be nice to see cutting off final excess overflow foam from the cracks and final prep sealing of the joints where tar sealer was removed. () great project video. I watched it twice! But still am not certain about the questions above. -RichK

I did this for 10 years slabjack. I raised entire garage floors up to 9-14 inches,sidewalks,drives, great way to make a living atl ga

I knew concrete lifts could be done without a huge air compressor rig. Secure set foam for the win.

This guy is an excellent instructor by telling, showing, observing, and praising/retraining as he goes along.

Good video. I strongly recommend safety glasses or even better a clear face shield when working with any expanding foam product. It squirts out under pressure unpredictably. A disposable Tyvek suit over exposed skin will prevent messy and really difficult cleanup.

I like that Leslie jumped right in and wasn't afraid to do and try something new. She had a good instructor too! 👍 I appreciate you taking the time to document showing someone on camera what it's like to learn how to do this process because a experienced professional doesn't always anticipate the things that a newbie needs to understand for a successful outcome. Good work all the way around by both of you! 👍👍😃

Thank you so much for this honest video, showing what really happens with most projects....all the unexpected things that come up and how you handled them. Really great, informative video!

A word of advice to anyone watching this video.... never assume it will go the same as "most jobs". There will be variables but don't let it scare you. It might be wise for the maker of this material to have a list of worse case scenarios to keep in mind and how to be aware of them and how to improvise based on your situation. Overall it seems incredible that it lifted it. I wonder how well the foam holds up in time being saturated in dirt year round.

Great video! I found the strategy of redrilling holes and layering the high density foam - from below - in conjunction with use of the ramps with the vehicle to weigh down the hinge point, most innovative. Thank you. Very smart.

This is me on every project and then people start to wonder if I know what I’m doing once I start using cars as weights and Amazon boxes for test blasts. Great video

This is a perfect no nonsense straight to the point video. I love it!

Super interesting and educational. One word of advice. Wear eye protection! Leslie nearly got an eyeful of foam. Yikes!

By the time this is all over, Leslie will be an expert!!

Would’ve probably been best to put some bolts through it, Jack it up to raise, then put foam to secure it at the proper height. There are ways you can put bolts through it, and chain them to 2x4s and use a hydraulic lack to raise it

Loved the video. Made me see that I can approach my concrete issues myself ...though my voids are very large at one end of driveway

Great detailed video guys! As a home owner and self DIY'er really appreciate how you worked with Leslie for her to do most of the work while learning the process as it went along. Thanks so much for the detailed explanations and documenting the process fully from start to end, not as a montage.

Terrific and honest project, honest pitch and great product. I would buy it! Thank you!

Awesome demonstration! This is on my pipeline for this spring. My concrete hasn't settled more than a 1/2", but I am thinking I'll do it as a preventative project to offset settling and ant work. Thank you!

I love how well you explain what is being done.

Love this guys attitude and work!!

I was waiting for him to say, "See you next week on 'This Old House', with Bob Villa"

Kudos to Leslie❤❤❤

This video was uplifting

Good job!!! Nothing like a woman or anyone trying or learning to do something that most people would hire a pro to do! You two taught me a little something and I got some work to do it seems....lol. Enjoyed the video!

Thank you. Real life, stuff happens. Sure ready to try this on my drive! Hope will save having to hire Pro Lift Co. and satisfaction of DIY. Finally some products on market for DIYers!

I just gotta $11,000 bid to do this to my sagging garage and driveway. Plus they fill in the cracks too and put something into the expansion joints. Just gunna do it myself now.

truly a good representation of a DIY project. Good explanations...

Good trigger and safety management 😋

Great presentation! I like this method and have a number of projects in mind. That existing crack between your slab sections very likely provides some interlock, which might cause your first injection area slab piece to actually lift the next piece. When there is differential elevation across a crack, I believe I would try to release the sections by cutting/chasing the crack with an angle grinder and a diamond blade - maybe a small drill also.

deserves more 👍🏼 thumbs up. good teacher. good offsider. good camerawork.

There you go, you answered any concerns I had regarding the longevity of foam. I only wish I saw this video sooner. I had a similar problem at a location and not knowing of your product went the harder way of jackhammering the slab and removing and doing a new driveway.... If I only knew!!!!

I just put 6 of these into a very sunk hawaii house foundation. It ate it all. 1 gun safety malfunctioned and i got blasted. The cans actually go well over ten minutes. I like the concept. wear protection. face shield even. I dont think the instructor emphasized the tight seal you need enough, and how to manage the ten minutes of foam you get. its really more like 12 minutes. This could use a lot more real detail. Good product.

Good job....thanks for sharing your Secure Set project and procedural tutorial

Wow …I learn a lot from this video… Thank you 🙏

Load locks to the top of garage header may be a good solution for holding top of slab from moving.

I would be concerned that I had drilled into a poorly located pipe and was now filling my bathroom with expanding foam! Great video showing how not every job goes according to plan and you need to adapt.

Very interesting. Glad you included things that can go wrong. Would like to see the homeowner using proper PPE. A dust mask and eye protection should always be worn. Drilling concrete creates silica dust which is potentially harmful. Otherwise, very informative.

Audience, Great DIY video for a home owner like myself🤜🏼🤛🏼🙌🏼.

Thanks for sharing. Great work.

I watched this entire video, thanks for sharing. I have a breezeway connected to another brownstone however the 3 large slabs of concrete leading into the breezeway have settled and pitch in the wrong direction towards my home, causing rain water to pool during extreme thunderstorms. In turn the pooled water seeps down into my foundation causing my basement to flood. I’m hoping that this product will work well enough to raise the concrete slabs within my breezeway giving me the desired slope to have water roll away from my home.

great video, a real learning curve when things don't work to begin with.

Great job 👍

Amazing repair

This guy is good teacher;)

Nice job guys👍….…Remember, WATER intrusion usually the main reason why our foundations are sinking especially when the foundation sitting on a nearly flat surface which reduce the water flow quickly away from the foundation…Therefore, foundation erosion starting to happen which weakening the concrete. I think I’ve found the problem on this driveway during the video shooting!! The downspout looks like directed and built within the brick wall and coming down just a foot away from the garage floor. I’m pretty sure if that downspout still there, this driveway will continue to sink! If not, then other surrounding foundations will be copied and eventually back to square one.

Great video

Hey, great video. I have a small area on my driveway that needs repaired. It’s, maybe 1/4 inch off… anyway, I called a professional…I just wanted them to use a filler to fix the crack. The pro educated me and explained settling, voids and foam lifting. Anyway, he proposed three options… the first option addressed the 2’ x 3’ area that needs caulked and apparently lifted 1/4 inch cost $2,500. Of course, for option 2, he wanted to “protect” my entire driveway (3 1/2 car size) that included a foam injection to create a barrier under the entire driveway for $7,500… and option 3 included options 1 & 2 with caulking the expansion joints and painting the driveway to make it look new for a cool $15,500!! Anyway, so glad I saw you video and introduced to your product… I will definitely give it a try!!! Thank you for your post!!

Once you have the slab where you want it, how do you finish off the project? Do you cap the holes with mortar? How do you clean off all the overfill?

Thank you very much . I have same problem in my driveway.

EXCELLENT ! Thank you. ( eye protection... ? )

Just what I need Thank you

You could run 4-6 anchors with metal straps along the garage floor to hold the “hinge” edge level.

For "weights" how about some 2x4 bracing from the top of the garage door? Takes 30 seconds to put three in with a bottom plate to hold down the concrete edge.

I bet it would help to get a piece of angle iron and anchor it into the concrete bridging the gap from driveway into the garage that way the slab ur trying to raise will go right where u want it to and not raise up higher than expected. So the angle iron would get anchored from the primary concrete into the garage concrete and anchor another angle iron same way at other end.

Very informative...thank you

By cutting a expansion cut were the crack was it might of been the solution for lifting the concrete maybe?

eye protection, get that stuff in your eye is a game changer. otherwise excellent!

I think using a boroscope would be handy for estimating how much foam to purchase and guiding it during the injection process. (Obviously, you'd need to keep the sticky material away from the lens.) eBay has them listed for about $25 that connects to a smartphone or tablet for viewing.

This video makes it look so simple, I hope it's this simple in real life! Want to come do my house next? ;)

The side of my stoop outside my front door and small patio area are sinking toward the exterior wall of our house. Would this system still work?

Excellent !

Can you suggest a product to fill in the drilled holes in exposed aggregate concrete? Thanks for the great video!

I had poly raise out to look at my garage that has sunk 3 in on one side they didn't want to do it. So looks like I'll be doing this. I'm thinking on drilling holes near the crack in the center "hinge point" and put some foam there before digging on the foundation and putting bottle Jack's under and slowly jack the garage up and then spray foam under using the pvc pipe on the end like your other videos. Or do you think just drilling holes threw out the slab and raising it like this video would be better? Reason I was thinking on spraying foam on the hinge point first is because it seats a little lower then the other side of the slab so if I bring up the wall side the hinge point would be lower than the other half.

I had a friend in MN who bought a brand new house. The next summer a section of her drive had dropped an inch. The next year it had gone down 2 more inches. She called the builder and they patched the drive. The next year it had gone down 4 inches. They dug down to see what was going on. It turned out there was a gap in her sewer line. She took the contractor and the city to court (it should have been inspected, but obviously not). How old was this house?

Hi Just a question here... Would it be better if Leslie was off the slab to be lifted and working from the fixed / level side? Cheers John

would it be worth the time and effort to try and slide a visual inspecting camera in the hole to see the extent of the voids?

How do you know when to stop dispensing so you don’t over do it?

What measures would I need to take to do this same thing to a load bearing concrete slab holding up a pretty weighty second-floor attachment? Would this even be feasible?

Great video presentation! I like to raise my driveway slabs at the garage opening using this Secure Set product. I am wondering where I can buy a drill bit like what this video is showing. It drills the concrete like butter. I need specs such as diamond drill bit or carbide or what it is and a seller site. Thanks.

How long does the foam last? I have a slab that keeps sinking after I have jacked up the concrete and filled underneath with crushed stone and cement several times in the past 15 years or so. I think because I live near Lake Michigan on sandy soil (you hit sand after about 2 feet or so), I will near get rid of this problem ...

Nice clip good on ya both :) May I get details of the foam product name and who makes it please?

I would like to try this but I fear my garage driveway is too complex. Mine is sinking unevenly due to a huge tree that used to grow where my drive way and garage was later poured. I'm thinking it would take a ton of this stuff to raise it, but maybe not. The tree was cut down around 1955 to 1965. The concrete was poured about 1980.

What size bit were you using? (Looks like a 1/2" chuck, 1/2' bit.) Also, what is the length? Thank you.

Do you have a video of spraying foam into a wall to aid old bat insulation?

Could the lift have benefitted by having slant drilled the holes as opposed to having drilled them perpendicular?

Wonder if i can order and you guys to come and make a video . We are out in the State of Micbigan.

Is there a second part or Part 2 To show clean up and re install of the expansion material?

I have a detached two-car garage that has a big crack down the center and both sides have sunk about four or five inches. Would it be feasible to use this product to level my garage?

I wish that I had seen this video a few years ago. I had several 2” slabs that became uneven after a tree rootball decomposed and rendered my backyard unusable.

nice video, does anyone know what is difference between the secure set and great stuff foam ? secure set more tough and load bearing more weight ? thanks

what keeps the foam from compressing over time, with driving over it seems like it will compact.

Would making a couple drill holes on the other side of the concrete next to you and see if there is a void on that as well?

Is it has better pressure than can spray? And what is adventage of foamjacking than just use self level mortar? Lastly, sry for lots of questions but I thought the foam harden under slab at the first job. How it keep going even they trying after foam harden. Because I couldnt see under slab it is hard to understand because commercial foamjacking was lift slab at once

Can I buy this product in Perth Western Australia My concrete around my pool is dropping inwards I’m not sure what to do .Thanks

I think cleaning out the expansion joints would have been the first thing to do before using the product. Good product though.

My cement patio is sinking down to where it meets my house foundation. Is there a risk of the foam pushing in the cinderblock foundation?

If I use all of the spray foam in the container, can I refill it or do I have to buy it again?

Does it matter whether your body weight is on the slab during work?

How much does that foam cost? So many holes do u think the concrete will be prone to cracking ? I would have put a probe a camera down there first to make sure its wasn’t sewer lines not causing that soil dispersement before drilling deeper or filling in foam

Im trying to buy, but can't get to the website link? Takes me to a download link? Thanks

I need to get a couple boxes of this I’ve got so many voids in my driveway when I bounce a basketball you can just hear how hollow it is

How do you determine the spacing of the holes?

How can I buy this product?

I’m just curious, what the cost would have been to remove that 9ft section and pour new concrete. I looked up the cost for the concrete lift. $500 per box.

You go left right, let the rise on the left and the lesser flow to the right create a void on the right side. Then fill the right and it will lift the right and create a void on the left again, go back left and repeat. Filling up the left and trying to pump more into the left will not work because there is no space unless you lift it, so lifting right creates more space. It is a problem if you fill up the whole space and have tight foam everywhere, you do not have any voids left to lift and create voids in the original space.

How long does the process take? How do you know when to stop so it doesn't rise too far???

Where did you buy the two-part foam from Amazon do you have the details on it
