Patio pavers sinking or uneven — Chicago, Illinois
Patio pavers that have sunk, shifted, or become uneven are usually caused by a poorly compacted or eroded base layer underneath. When the gravel-and-sand base settles unevenly — from water washing away sand through the joints, poor drainage directing water under the patio, tree roots pushing from below, or simply insufficient compaction during original installation — individual pavers drop, creating trip hazards and pooling water. The fix depends on the extent: for a few sunken pavers, a landscaper or mason lifts the affected pavers, adds and compacts fresh base material, re-levels the sand bed, and resets the pavers ($200–$800 for a small area). For widespread sinking, the entire patio may need to be lifted and the base re-graded and compacted ($2–$5 per square foot). Adding polymeric sand to the joints after repair prevents future washout. Addressing the drainage issue that caused the erosion is critical — otherwise the pavers will sink again.
