Why Does Concrete Settle?
Concrete may settle for multiple reasons like poor drainage, low-quality compaction, damaged site conditions, tree roots, and more. The most common reason is when water from gutters or rainwater removes dirt from concrete surfaces like sidewalks or driveways. It creates voids or pockets into the concrete, which causes it to settle.
Concrete may also settle if there is clay-rich soil. When the soil is saturated with water, it expands. Then, when the soil dries, it contracts. Thus, the soil remains unstable, which causes concrete to move and sink.
