In Highland Park, Illinois, concrete slabs, patios, driveways, or sidewalks are lifted and leveled using a technique called polyjacking. Polyjacking is done by using expanding and lightweight polyurethane foam. It is a quicker and more reliable, non-toxic alternative to mudjacking for leveling concrete.
Why Does Concrete Settle?
Several components such as inadequate compaction, poor drainage, inappropriate site conditions, and tree roots, can cause concrete to settle. Rain and gutter water eroding debris from your driveway or sidewalk is the most common cause of the concrete sinking. Because of cavities or pockets that form beneath it, your concrete can shift over time.
Another element is the existence of clay-rich soil, which changes in size in response to moisture levels. This soil expands when it is wet and shrinks when it is dry. The change in moisture content renders the ground unstable, which causes the concrete to move and sink.
Concrete Leveling Using Polyjacking
The soil must be strong and durable for slab replacement. If that does not happen, it might be unable to carry the weight of the concrete. The slab can only be replaced if the soil is stable.
