The PolyLevel System is a state-of-the-art approach to repairing sinking concrete slabs. It combines the concept of mudjacking with the most advanced technology. Instead of using a mix of mud and cement to raise the slab, PolyLevel utilizes high-density polyurethane specially engineered for this purpose./Supportworks
The advantages of using PolyLevel over conventional mudjacking are many. PolyLevel is lighter than mud-cement mixes (4lbs per cubic foot opposed to 120lbs) so it will not overburden the loadbearing soil beneath the concrete and lead to further settlement.
The expanding nature of the material allows it to penetrate crevices in the soil, completely filling the cavity and safely raising the slab to the desired level.
PolyLevel can be installed in just one day, through smaller, dime-sized holes drilled in the concrete and just 15 minutes after installation you can walk or drive over the slab!There is no need for extended periods of curing, as is the case with cement and mud compounds.
