How to Repair Uneven Patio Pavers

Patios naturally settle over time as the ground beneath them shifts and compresses. When a paver dips, it creates an unsightly hazard that collects water and trips anyone walking across it. Fixing it isn't just about aesthetics; it prevents further erosion of the base layer underneath. Successful repair requires patience during the leveling process. You are essentially rebuilding a miniature foundation for each affected stone. If you do this right, the patch will be indistinguishable from the rest of the patio and will hold firm for years against the weight of foot traffic.

1. Lift and Remove Sunken Pavers. Remove the sunken pavers using a trowel or flat-head screwdriver to pry them up. If the stones are locked tight with sand, start by clearing the joint material from around the edges.
2. Dig Out Unstable Bedding. Scoop out the old sand or stone dust underneath the low spot. Remove enough material to account for the thickness of your new base layer.
3. Add Compactable Base Material. Fill the void with coarse, angular paver base or leveling sand. Mound the material slightly higher than the surrounding area to account for settling.
4. Tamp Down Foundation Solid. Use a hand tamper or a heavy piece of wood to pack the bedding down firmly. The surface should be flat and dense enough to support weight without sinking further.
5. Tap Pavers Flush Perfectly. Place the pavers back into their original spots. Tap them down firmly into the sand using a rubber mallet until they sit flush with their neighbors.
6. Seal Joints with Polymeric Sand. Pour polymeric jointing sand over the reset area and sweep it into the gaps between stones. Mist the area lightly with water to activate the binding agent.
