Soil erosion and settlement often cause concrete slabs in patios, sidewalks and driveways to sink into the ground. This type of settlement isn't just unsightly; it can also cause more damage and can be a safety hazard. Water tends to pool on sunken surfaces and unleveled floors cause a trip hazard.
Until now, the only solution available to repair sinking slabs was mudjacking, a process that involves drilling holes in the slab to inject a mixture of cement and mud underneath, to raise it back to level.
TerraFirma Concrete Leveling 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, our system utilizes high-density polyurethane specially engineered for this purpose.
The advantages of using our system over conventional mudjacking are many. The polyurethane system we use is lighter than mud-cement mixes (4lbs per cubic yard opposed to concrete's 120lbs). It will raise the slab without adding a lot of weight to it.
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.
TerraFirma Concrete Leveling is also environmentally-friendly and made with recycled materials. It can be installed in just one day, through smaller, penny-sized holes drilled in the concrete and just 5 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.
