For those that appreciate architecture and design, a semicircular brick patio may add just the right touch of personality to a backyard. Brick patios are popular for space off of a deck, or simply on their own. Look at these steps for installing your own semicircular brick patio, which is easier than you might think.
Measure the area for the brick patio. Create a layout for your semicircular brick patio design using gardening spray paint or chalk to mark the area as appropriate. You may need a compass to assist in marking a perfect semicircle.
Place edging along the circumference of the semicircular line. Till the soil and flatten the soil with a flat surface board to create a level area for the bricks. You may want to consider purchasing sand or a lining to help with even placement of the bricks during the installation phase.
Purchase bricks meant for semicircular patterns for simplicity. This will limit the amount of cutting necessary at the center of the patio.
Lay each brick down, beginning from the outside of the circle, placing bricks close together. Continue this for several layers, regularly pushing the bricks together to maintain the shape. Place the cut bricks in the center of the patio design.
Pour additional sand over the patio to fill the tiny cracks between the bricks. Sweep away excess sand and spray off the patio with a garden hose. Secure the outside layer of bricks by the surrounding soil.
