What Is This Filler That Is Used For Concrete Cracks?


I've noticed when I see large cracks in concrete, it's filled with a sort of rubbery, caulk type filler. Doesn't seem to be just concrete patch.

Curious what it's called?

Doesn't seem like normal concrete crack filler. This stuff is spongy. Almost like the stuff that used to be around the concrete in older pools in between joints.

usually polyurethane or 100& silicone 'sealants',,, 1st diamond saw crack then install either self-leveling OR non-sag,,, you do NOT want 3sided adhesion - ONLY both sides of the crack,,, put tape OR closed cell backer rod in the bottom to prevent btm adhesion,,, sikaflex is 1 brand of polyurethane

I'm not sure, but I think City Decks was doing a repair and he was using something like this only his job was much cleaner.

Sikaflex levels out like that? I thought it was thicker and stickier.
