How to Reset Sunken Pavers

Pavers are built to move with the ground, but over time, shifts in soil and poor drainage often leave behind low spots that pool water and create tripping hazards. When a walkway or patio begins to dip, the solution isn't to pile more sand on top, but to reset the foundation itself so the pavers sit flush with the surrounding surface. A job done well results in a seamless, level transition that resists further shifting. By addressing the sub-base, you are resetting the integrity of the entire structure rather than just applying a temporary bandage to the symptoms.

1. Remove and label pavers. Remove the sunken pavers using a pry bar or a flat-head screwdriver. Set them aside on a flat surface in the order they were removed so you can easily replace them.
2. Dig down to solid ground. Remove the old bedding sand and inspect the gravel base beneath. If the gravel is also sunken, remove enough to expose the compacted sub-soil.
3. Pack the gravel base. Add a small amount of new crushed stone base to the hole. Use a hand tamper to compress the gravel firmly until it is solid.
4. Screed the sand smooth. Pour one inch of leveling sand over the compacted gravel. Use a straight edge or a scrap piece of wood to screed the sand until it is smooth and level with the surrounding area.
5. Reset pavers flush. Place the pavers back into their original spots, pressing them firmly into the sand. Use a rubber mallet to gently tap them down until they are perfectly flush with the neighboring stones.
6. Lock in the joints. Sweep polymeric sand into the gaps between the pavers. Use a leaf blower to remove excess sand from the surface, then mist the area lightly with water to activate the binding agents.
