Step 1)

Injection holes are strategically drilled around the areas where the concrete is sunken and requires lifting.

Step 2)

Once everything is prepped and the hose and materials are in place, the polyurethane foam is injected through the holes. It expands to fill the space underneath the concrete slab, using the slab itself to drive the foam into the crevices, there by lifting the concrete back to its original position.

Step 3)

Once the concrete is stabilized and lifted to the proper protocol, the injection holes are filled with new cement, allowing you to use your surface immediately.


Polyurethane concrete raising uses a foam material that is injected under the slab. When the components of this material are mixed, a reaction causes the material to expand. This expanded foam fills any voids beneath the slab and raises the concrete. This material will never lose density, is permanent and weighs only about 2 lbs. per cubic foot.
