Concrete Raising and Leveling

Concrete leveling is a standard method used to raise, level, or stabilize existing concrete slabs without excavation or invasive processes or the added cost of pouring new concrete. Concrete slabs often crack as a result of voids, soil erosion or impaction.

Small holes (⅝’) are drilled into the slab of sunken concrete in strategic locations then a high-pressure polyurethane injection is pumped under the existing cracked or sunken slab which lifts the concrete in place, leveling out the surface. When hardened the polyurethane mixture solidifies to the hardness of concrete. This process works well on cracked garage floors, concrete driveways, patios and pool decks, sidewalks, and interior floors.

The development of cracks within concrete is common and often caused as the concrete drys and shrinks as it ages. PGI will determine if the natural shrinkage process caused the cracks or if there is a more serious underlying cause.

Depending on the severity of the cracks, PGI will utilize several methods of repair, polyurethane foam injection; pressure grouting or mudjacking, or the installation of helical piers with slab brackets.
