1. Pavers are Sinking: Sinking pavers are a sign that there is a drainage problem underneath. To fix this, remove your pavers, properly reset the ground and foundation, and re-lay your paver stones.
2. Pavers with Poor Drainage: Excess water pooling on top of sunken pavers indicates poor drainage. If this is not corrected, during the warmer months, the pooling water can freeze underneath your pavers, and completely upset the foundation. It’s best to remedy this as soon as possible with the same steps as the sinking pavers above.
