PolyLift is a relatively new process for concrete leveling that is growing in popularity due to how quickly the slab can be used after the process is completed.
Uneven concrete is an eye sore and, all too often, a hazard. Concrete slabs are supported by the soil below, meaning that it shifts and sinks as the soil erodes and washes away. A solution to uneven concrete is filling in the empty space left from soil erosion with a substance that will lift the slab back into place. Because polyurethane is waterproof, it will not erode or wash away. It is also light but resilient, and cures in about 15 minutes after injection.
Much like mudjacking, the PolyLift process starts with strategically placed holes being drilled through the concrete slab. The foam is injected to fill the void caused by soil erosion, lifting the slab back into place. The drilled holes are filled and the concrete slab can be walked on or used only minutes after the process is completed.
Leveling Concrete Slabs
When a concrete slab is no longer level, it is usually due to soil erosion that is caused by groundwater and weak soil types that erode or compact. The purpose of concrete leveling (link to ‘concrete leveling’ page) is to bring the slab back to level, without having to replace the entire slab. The benefit of concrete leveling is that you are working with the existing slab, meaning that you do not end up with two-toned concrete and do not have to pay for an entirely new slab.
