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.
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 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.👍🏻
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.
@@TheProCut17 SealBoss 1640 Hi Strength Instant Water Stop and SlabLifter Foam - 1/2 Case (6) Starter Kit 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.
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.
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.
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'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.".
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.
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.
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.
@@bombardment92actually a much different type of foam. The foam he used may be working for that small project, but would never hold up under heavy traffic like a road over a bridge. He did say it settled slightly, and I believe that was likely due to the type of foam he used. There are two kinds, single stage (like what he used, and 2 part which is what the professional PolyJackers use.
