Proven, Industrial Strength Concrete Repair
Acme Concrete Raising & Repair’s Smart Lift System is a trusted and proven process for every type of settled concrete flatwork from large highway projects to residential sidewalks. Acme Concrete Raising and Repair is the first and longest running concrete raising contractor in the Chicagoland area focusing specifically on polyurethane injection technology.
Acme’s concrete polyurethane foam raising process provides maximum subgrade strength and costs less than traditional concrete repair or replacement. The Northwest Chicago suburbs are subject to extreme environmental changes — our concrete lifting foams will not shrink or expand due to moisture changes, and will not wash out like aggregate-based slurries used by mudjacking companies.

Holes about the size of a dime are drilled into the settled concrete slab. Special injection ports are then installed allowing a clean, controlled injection of the polyurethane lifting foam.

A polyurethane injection gun is securely attached to the ports. Controlled injections are performed resulting in a two-part polymer flowing through the space between the structure and its failed subbase. The polymer forms a structural foam that fills voids while raising and leveling the settled structure.

Once the concrete has been raised, the lifting material is fully cured in about 15-minutes, allowing immediate, unrestricted use of the area. The injection ports are then easily removed and the holes are filled with a high quality grout leaving them virtually unnoticeable.
