Can pavers be installed over concrete?

Yes, pavers can be installed over concrete. Installing pavers over concrete offers several benefits. It’s a faster and more cost-effective option compared to removing the existing concrete. Additionally, it allows you to create a new surface without significantly altering the existing grade of your yard.

Here are a few things to know about installing pavers over concrete:

Prepare the surface

The concrete needs to be clean, dry, and free of any debris, dirt, oil, etc. It’s best to use a pressure washer to clean it thoroughly.

Leveling layer

You’ll need to add a leveling layer on top of the concrete to create a uniform surface for the pavers. This is usually a compacted layer of coarse sand or pea gravel about 1-2 inches thick.

Bedding sand

Once the leveling layer is installed and compacted smooth, add a 1/2-1 inch layer of fine sand or polymeric sand. This creates a mortarless bond between the pavers and leveling layer.

Lay pavers

Starting from a straight edge, lay out and install the pavers according to your desired pattern. Use spacers between pavers.

Compact and finish

Compact the newly laid pavers with a plate compactor or vibratory roller. Then sweep in extra bedding sand to fill cracks.

Seal

For paved areas that will get foot or auto traffic, apply a high-quality, breathable paver sealer to protect the installation.

However, there are also some considerations. The added height of the pavers may affect drainage and access to doors or other structures. Additionally, the weight of the pavers could put additional stress on the existing concrete, so ensuring its structural integrity is crucial.
