Expanding Foam To Lift Concrete Slabs

So how do you raise a concrete slab with foam.

Expanding foam to lift concrete slabs.

Heavy duty polyurethane foam for slab lifting soil stabilization among the leading high density polyurethane foam products available ap lift 475 offers a powerful solution that is traffic ready in 15 minutes. Use 5 8 inch masonry bi t to drill a hole through the concrete and spray the foam into it. Polylevel combines the already proven technique of concrete lifting with a specially engineered two part expanding foam that makes it possible to permanently restore the concrete surface with little downtime and disruption. The first step is to drill holes in the problem concrete.

With our wet northwest winters the soil under concrete slabs can become saturated and soft or wash out completely. The risk becomes higher when the soil below the slab is poorly compacted. Once the holes have been set the geolift is injected in between the concrete and the dirt. Moving in the other direction is an expanding foam called polylevel.

The following video shows how dramatically effective this is. This two component high strength high density hydro insensitive structural polyurethane foam supports 14 000 lbs per square foot. Place chalk marks in a row on the slab extending from the low point to the beginning point of the slag spacing. Locate the dips get the right equipment and foam.

Foamjection offers numerous advantages for homeowners and business owners who need concrete repaired quickly and efficiently.

Drill a hole. Once this occurs the only way to regain control over the slab is to cut through the layer of foam and attempt another lift again.

Foam lifting is a modern approach a more modern approach to concrete leveling is through the use of expanding polyurethane foam that provides a wider range of benefits than traditional mud jacking grout techniques.
