Concrete leveling helps to raise and level concrete slabs, sidewalks, patios, and driveways. This process involves polyjacking, a method in which polyurethane foam is used. It is a non-toxic, quick, and long-lasting process when compared to other concrete leveling solutions.
Why Does Concrete Settle?
Concrete can settle due to plenty of reasons such as lack of proper drainage, poor compaction, tree roots, as well as bad site conditions. The primary cause for concrete settlement is rainwater or gutter water washing out debris from underneath driveways and sidewalks. The voids or pockets created consequently can lead concrete to settle.
Another major cause of concrete settlement is the contraction and expansion of clay-rich soil due to changing moisture content. Consequently, the ground becomes unstable, causing the concrete to shift and sink even more.
Concrete Leveling Using Polyjacking
The soil beneath the concrete surfaces should be strong enough to hold its weight. Otherwise, it will be unable to support the weight of the concrete, making it impossible to replace the slab.
