Lifting of Sunken or Uneven Concrete
Concrete lifting has many advantages over tear-out and replacement: the surrounding landscape is left undisturbed, the procedure usually takes only a few hours, and objects do not necessarily have to be removed from the surface of the concrete. The cost of concrete lifting is significantly lower than replacement, often at 1/3 to 1/4 the cost.
CSL offers two material choices for commercial concrete lifting: grout injection or polyurethane foam injection. Each carries a 5 year warranty against any sinking or settling 1 inch or more.
With grout injection, a 2 inch hole is drilled through the concrete in several places, and a specialized grout mixture is injected, which lifts and levels the area. The corrected area can be used again several hours after the procedure.
With polyurethane foam injection, a small 3/8 inch hole is drilled through the concrete in several places, and a lightweight and very durable polyurethane foam is injected, which lifts and levels the area. The corrected area can be used again 30 minutes after the procedure.
Void Filling and Soil Stabilization
Areas where soil has settled leaving voids under concrete structures can lead to many future problems. Polyurethane or grout injection can be used for void filling as well as for stabilizing loose or unstable soil. Compaction grouting or permeation grouting techniques are used, depending on the situation.
