Concrete leveling in Evanston is done by lifting and leveling concrete slabs, patios, driveways, or sidewalks. This process is called polyjacking, in which expanding polyurethane foam is used. It’s a non-toxic concrete leveling method that is faster and more robust than other solutions like mudjacking.
Why Does Concrete Settle?
Concrete can settle for several reasons, such as insufficient compaction, poor drainage, unsuitable site conditions, and tree roots. The most prevalent cause of concrete sinking is rain and gutter water clearing out debris from beneath your driveway or sidewalk. Your concrete can move because of voids or pockets that develop beneath it.
The presence of clay-rich soil, which alters in size in response to moisture levels, is another factor. When this soil gets moist, it expands, and when it dries out, it contracts. The soil becomes unstable due to the change in moisture content, which causes the concrete to shift and sink.
Concrete Leveling Using Polyjacking
Soil that is equally solid and durable as the concrete itself must support it to improve durability. If that does not happen, it might be unable to carry the weight. The slab cannot be replaced if the problem is unstable soil.
