How We Do It

When the components of polyurethane are mixed, a reaction causes the material to expand.  This expanded foam fills any voids beneath the slab and raises concrete.

Polyurethane foam never loses density, is lightweight, and is permanent.

Our polyurethane foam method consists of the following steps, conducted in a dust-free, clean environment with no disturbance to nearby areas including landscaping and lawns.


Step 1.  Drilling ⅝” injection hole(s) (the size of a dime) strategically through the slab into the subgrade.


Step 2.  Connecting the injection gun to a tapered delivery port that is installed into the hole(s).


Step 3.  Injecting polyurethane foam into the holes which fills the space under the concrete slab, using the concrete slab itself to drive the foam into the crevices to lift the concrete.


Step 4.  Repeat injecting foam until all areas of sunken concrete lifts to desired level.


Step 5.  Upon leveling, injection holes are filled with a non-shrink grout, eliminating cracking and shrinkage.


Vacuum hose is attached to our drill, making clean up quick and easy.

 we are committed to working in a clean, dust-free environment
