How to Fix Sunken Patio Pavers

Sunken patio pavers can be an eyesore and a hazard. They can create tripping hazards and make your patio look uneven and unsightly. If you have sunken pavers, you don't have to replace them. You can fix them yourself with a little effort and the right tools.

What Causes Patio Pavers to Sink?

There are several reasons why patio pavers may sink. Some of the most common causes include:

Poor soil compaction: When the soil under your patio pavers is not properly compacted, it can settle over time, causing the pavers to sink.
Inadequate drainage: If your patio does not have proper drainage, water can pool under the pavers and cause them to sink.
Tree roots: Tree roots can grow under your patio pavers and lift them up, causing them to sink.
Frost heave: In cold climates, frost can heave the soil under your patio pavers, causing them to sink.

Tools and Materials You Will Need:

Paver lifting tool
Rubber mallet
Level
Sand or gravel
Compactor

Step-by-Step Instructions:

1. Remove the sunken pavers: Use a paver lifting tool to carefully remove the sunken pavers. Be sure to lift them straight up to avoid damaging the surrounding pavers.

2. Level the ground: Once the sunken pavers are removed, use a level to check the ground beneath them. If the ground is uneven, add or remove soil as needed to level it.

3. Compact the ground: Once the ground is level, use a compactor to compact it. This will help to prevent the pavers from sinking again.

4. Add sand or gravel: Spread a layer of sand or gravel over the compacted ground. The sand or gravel will help to distribute the weight of the pavers and prevent them from sinking.

5. Replace the pavers: Carefully replace the pavers on the sand or gravel. Use a rubber mallet to tap them into place. Be sure to level the pavers as you replace them.

6. Compact the pavers: Once the pavers are in place, use a compactor to compact them. This will help to keep them in place and prevent them from sinking.

Tips:

If the sunken pavers are cracked or broken, you will need to replace them.
If you have a large number of sunken pavers, you may want to rent a power compactor.
To prevent your patio pavers from sinking in the future, be sure to compact the soil properly before installing them and install a proper drainage system.
