How to Level Sunken Patio Pavers

Patios are constant works in progress, especially when the earth beneath them shifts. A sunken paver isn't just an eyesore; it's a tripping hazard that collects water and eventually compromises the integrity of the entire surrounding field. When you notice a dip, addressing it immediately prevents the sand base from washing away further, which would turn a single-stone repair into a full-scale rebuild. Restoring a level patio is about patience and precision with your foundation. Success looks like a patch that is perfectly flush with the existing grid, with no rocking when you step on it and joints that match the surrounding pattern. Done well, you won't be able to tell which stones were lifted and which stayed in place.

1. Free the Stuck Stones. Use a flat-head screwdriver or a thin metal pry bar to wiggle the first paver out of the grid. Once the first stone is free, use your hands to lift adjacent stones to create enough workspace.
2. Expose the Problem. Scoop out the existing sand or stone dust from the depression. Inspect the area for roots or compacted soil that may have caused the initial sinking.
3. Pack the Base Solid. Fill the void with fresh paver base or coarse sand, slightly overfilling the hole by about an inch to account for settling. Compact this material firmly using a hand tamper or a heavy block of wood.
4. Strike It Dead Level. Screed the surface of the new base using a straight board to ensure it is perfectly flat and level with the bottom of the adjacent, undisturbed pavers. Double-check the depth to ensure the reset pavers will sit flush.
5. Tap Into Place. Place the pavers back into the hole, starting from one corner and working outward. Ensure each stone is set tightly against its neighbor to maintain the integrity of the joint pattern.
6. Lock the Joints. Pour polymeric joint sand over the area and sweep it into the gaps using a stiff-bristled broom. Ensure all joints are completely filled to lock the stones in place.
