What causes concrete to sink?
Short answer: Concrete sinks when the soil beneath it compresses, washes out, or shifts. Common causes include poor original compaction, irrigation and downspout runoff, plumbing leaks, expansive clay soils, and root activity.
In San Diego, irrigation runoff and occasional heavy rain are the most frequent triggers. Water that runs along the slab edge can carry fine soil out from underneath the concrete over time, leaving voids.
Once a void forms, the slab eventually settles into it under its own weight or traffic load.
Lifting alone does not solve the cause. Drainage and irrigation issues should be corrected so the same settlement does not happen again.
