How to Build a Patio Using Concrete Blocks

Building a patio using concrete blocks is a great way to add style and functionality to your outdoor space. Concrete blocks are durable, easy to work with, and relatively inexpensive. With a little planning and effort, you can build a beautiful and long-lasting patio that you and your family will enjoy for years to come.

Materials You'll Need

Concrete blocks
Sand
Gravel
Landscape fabric
Edging
Level
String line
Tamper
Masonry adhesive
Mortar
Joints
Sealant

Step 1: Prepare the Base

The first step is to prepare the base for your patio. This involves clearing the area of any grass or debris, then excavating the soil to a depth of about 6 inches. Once the area is excavated, you'll need to level the ground and compact it with a tamper.

Step 2: Lay the Gravel and Sand

Once the base is prepared, you'll need to lay down a layer of gravel and sand. The gravel will help to drain water away from the patio, while the sand will provide a level surface for the concrete blocks.

Step 3: Install the Landscape Fabric

To prevent weeds from growing up through the patio, you'll need to install landscape fabric over the gravel and sand. The landscape fabric should be cut to size and overlapped by at least 6 inches at the seams.

Step 4: Lay the Concrete Blocks

Now it's time to start laying the concrete blocks. Begin by laying out a string line around the perimeter of the patio. This will help you to keep the blocks straight and level. Apply a bead of masonry adhesive to the bottom of each block before placing it in position.

Step 5: Level the Blocks

Once the blocks are in place, you'll need to level them. Use a level to check the blocks and make any necessary adjustments. You can use a rubber mallet to tap the blocks into place.

Step 6: Install the Mortar

Once the blocks are level, you'll need to fill the joints between them with mortar. The mortar will help to hold the blocks in place and prevent weeds from growing up through the joints.

Step 7: Install the Joints

Once the mortar has cured, you can install the joints. The joints will help to protect the mortar from the elements and give the patio a finished look.

Step 8: Seal the Patio

To protect the patio from the elements, you'll need to seal it. You can use a clear sealant or a tinted sealant. The sealant will help to keep the patio looking its best for years to come.
