Why Does Concrete Settle?
Concrete settles for numerous reasons, including poor drainage, bad site conditions, low-quality compaction, and unwanted tree roots. The most common reason we see is when the rainwater or water from gutters washes away dirt from under your sideways and driveways. It creates voids or pockets beneath the concrete surface, which causes it to settle.
Another factor that may allow the concrete to settle is clay-rich soil. The soil expands when it’s saturated with water. Then when the soil dries out, it shrinks. Due to such changes in moisture content, the soil becomes unstable. This instability in the soil makes the concrete move and sink.
