Poly Pumping is an injection of polyurethane pumped under a concrete slab. Grout Pumping is ejecting a concrete grout material under a concrete slab.

Both polyurethane and concrete grout pumped under a concrete slab serve the same purpose. Each has their own pros and cons.

Poly/grout Pumping is a technique used to lift lite structures and fill the void under a concrete slab.

Some of the lite structures are:

Small room additions

Patios

Driveways

Sidewalks

Roads

Floating slabs

Poly/grout pumping is also widely used in commercial applications that include:

Repairing roads

Drainage Void Filling

Trip Hazard Repair

Precision Concrete Leveling

Grout Pumping uses a 2-inch hole drilled in the slab to pump the grout under the slab. Grout Pumping takes longer for the material to dry and is not very accurate.

Meanwhile, poly pumping only uses a 3/8-inch hole. The material dries very fast and is very accurate. Poly pumping is approximately twice the price as Grout Pumping. Contact Crown Leveling, Inc. to see which one works best for you.

Poly/Grout Pumping is used for both residential and commercial applications. Although Poly/Grout Pumping is a technique used a lot more in commercial properties where there are trip hazards. Poly/Grout Pumping can level and smooth out uneven joints of the concrete.
