Cracks
Water infiltration will weaken the soil under the concrete slabs causing them to shift and crack. ALL cracks need to be sealed!
PolyLevel
PolyLevel utilizes high-density, expanding polyurethane foam to raise slabs back to a desired level. This is done by boring small (penny sized) holes in the slab, and using specially designed equipment to inject a structural grade polymer into the void.
Cracks
As soon as cracks start forming it is time to get them professionally sealed. They will only get worse over time.
NexusPro
Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble or dry. It fits into homeowners' busy lifestyles, too - drying time is a fraction of that needed for other urethane-based caulking products.
