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.
NexusPro Sealant
Frontier Foundation & Crawl Space Repair's NexusPro sealant is a permanent solution to cracked seams. After the void is filled, the expanding properties of the polyurethane foam allows for an accurate lift and leveling of the slab. Finally, the small holes are grouted and sealed, and the slab is completely restored.
