Expanding Foam To Lift Concrete Slabs

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.

Expanding foam to lift concrete slabs.

In this scenario you will have created a bridge of foam lifting multiple slabs. Foamjection offers numerous advantages for homeowners and business owners who need concrete repaired quickly and efficiently. The risk becomes higher when the soil below the slab is poorly compacted. Drill a hole.

If material reacts too slowly it can travel under and beyond the slab you are trying to lift and then expand. The stuff is designed to intentionally move whatever s adjacent to the gap it s being sprayed into. Foamjection combines concrete lifting with a specially engineered expanding foam making it possible to permanently restore the concrete surface with little downtime and disruption. Locate the dips get the right equipment and foam.

Moving in the other direction is an expanding foam called polylevel. Time and money is lost. Use 5 8 inch masonry bi t to drill a hole through the concrete and spray the foam into it. Locate the point at which the slab begins to sink into the soil by placing a carpenter s level onto the surface.

The following video shows how dramatically effective this is. The foam will fill up the parts of the concrete that are uneven and will raise it to the proper height. 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. Once the holes have been set the geolift is injected in between the concrete and the dirt.

How to raise concrete with foam step 1. This two component high strength high density hydro insensitive structural polyurethane foam supports 14 000 lbs per square foot. With our wet northwest winters the soil under concrete slabs can become saturated and soft or wash out completely. The first step is to drill holes in the problem concrete.

Place chalk marks in a row on the slab extending from the low point to the beginning point of the slag spacing. So how do you raise a concrete slab with foam. Holes should be no less than six inches away from the edge of the concrete. The foam will expand and harden filling the void in the ground and leveling the driveway.

The foam lifting technique is a fine tuned system that is unique to every job that is tackled.
