The Real Seal offers concrete leveling services in Oak Park, Illinois using polyjacking to raise and level sinking concrete slabs, patios, pathways, and driveways. Expanding polyurethane foam is used in this method. Compared to other alternatives like mudjacking, it is a non-toxic concrete leveling method.
Why Does Concrete Settle?
Many factors cause concrete to settle, including poor drainage, compaction, site conditions, and tree roots. The most common cause of concrete settling is when water from gutters and rain washes dirt out from under your sidewalk or driveway. This creates pockets or voids underneath your concrete causing it to settle.
Another factor that causes concrete settlement is clay-rich soil that expands and retracts according to its moisture content. This clay-rich soil expands when it is saturated with water and shrinks when it is dried out. This change in the moisture content creates unstable soil, which leads the concrete to move and sink.
Concrete Leveling Using Polyjacking
Concrete should be supported by soil that is as stable and strong as the concrete itself. Otherwise, it might not be able to support the weight. If the problem is weak soil, the slab cannot be replaced.
