How to Build a Durable and Stunning Concrete Block Patio

Transform your outdoor space by constructing a concrete block patio. Whether you desire a cozy lounge area or an expansive entertaining space, this practical guide will equip you with the essential steps to achieve a stunning and durable patio.

1. Planning and Site Preparation

Thoroughly plan your patio's size, shape, and location. Mark the perimeter with stakes and string. Remove any existing vegetation and level the ground. Create a 6-8 inch deep excavation and compact the soil using a plate compactor.

2. Laying the Base

Spread a 4-inch layer of compacted crushed stone evenly over the excavation. This base provides drainage and support. Over the crushed stone, install a layer of geo-textile fabric to prevent weeds and stabilize the base.

3. Setting the Concrete Blocks

Lay the first course of concrete blocks on the geotextile fabric. Use a level to ensure they are perfectly even. Dry-stack the blocks without mortar to determine the best layout and make necessary adjustments.

4. Installing the Edging

Edge the perimeter of the patio with concrete pavers or edging stones. This will prevent the blocks from shifting and define the patio's boundaries. Dig a trench around the perimeter and set the edging slightly below the level of the blocks.

5. Preparing the Mortar

Mix concrete mortar according to the manufacturer's instructions. The consistency should be similar to that of peanut butter. Use a mortar mixer to ensure thorough mixing.

6. Laying the Mortar and Blocks

Apply a layer of mortar to the first course of blocks. Set the second course in place, pressing down firmly to ensure good contact with the mortar. Ensure the blocks are level and aligned. Repeat this process until all courses are laid.

7. Finishing Touches

After the mortar has set, sweep sand into the joints between the blocks. Tap it in using a rubber mallet to fill and smooth the gaps. Allow the patio to cure for at least 7 days before applying a sealant to protect it from the elements.

Tips:

Use a large format level to ensure the patio is flat and even.
Incorporate subtle slopes for water drainage.
Consider adding decorative patterns or contrasting colors to the blocks.
Protect the patio from the sun with an umbrella or shade structure.
