Steps to Raising Concrete

Step 1

Our professionals will strategically drill 5/8" injection holes around the areas the concrete has sunk and requires lifting.   

Step 2

Once everything is prepped and the hose and materials are in place, the polyurethane foam is injected through the predrilled holes which fills the space underneath the concrete slab, using the concrete slab itself to drive the foam into the crevices, thereby lifting the concrete back to its original, correct level. 

Step 3

Upon completion of leveling the concrete, the injection holes are filled discretely with new cement allowing you to use your surface immediately.


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