Circle-shaped patios create alluring landscaping surfaces in yards and gardens. Circular patios add visual appeal while also providing a definite seating area outdoors. The round shape of such a patio rarely sits beside a home; rather you are likely to find it in the middle of a lawn or garden to break up otherwise wide open space. Brick serves as a material for building round patios, as you can place the bricks in rows to carry on the circular theme. Once you have installed the patio, you may choose to use the space for either a single bench or to support a patio table and chairs.
Choose a location for your patio. Check with local building authorities and power companies to ensure that you do not build your patio over your septic tank, underground pipes or any subterranean wires. You may also need to get a building or digging permit before you start your patio project.
Drive a stake into the centre location of your patio. Tie a sting to the stake and extend the string to the desired radius of the patio. Use a small strip of duct tape to tape the end of the string to a can of white spray paint. Pull the can of spray paint around the stake, spraying a white line to mark the edges of the patio.
Remove the stake and excavate the area inside the circle using either a shovel or a spade. Dig down to a depth of 6 inches to construct a firm foundation for your patio.
Check for uniform depth using the level, removing high areas and filling low areas of soil as necessary. To promote better drainage and extend the life of your patio, consider sloping the patio away from centre -- making the centre of the patio slightly higher than the edges.
Compact the soil iusing a manual soil compactor to create a solid base for the patio. To do this, pound the broad and flat end of the compactor against the ground repeatedly until you can no longer make impressions in the ground with your feet.
Apply a 2-inch layer of crushed stone to the area, level it as desired and compact it with the soil tamper. Once compacted, apply a second 2-inch layer and compact this final stone layer as well.
Apply a 2-inch layer of masonry sand to the patio site, over the layers of crushed stone. Compact this layer of sand using the soil compactor and by misting the sand with a garden hose.
Start setting the bricks into place in the patio site, over the sand layer. You have several options concerning the placement of each brick when installing a round brick patio. Most people choose to make the bricks follow a circle pattern, so place bricks around the outside of the excavated area, in a circle shape. Complete placing one entire row before installing any others. Leave gaps between the bricks as necessary to create the circles of each row.
Continue placing rows inside of rows until you have to switch to a smaller size brick or place a single brick in the middle. You may have large gaps between the bricks, but do not worry, you will fill them in during the next step.
Dump another load of masonry sand over the circular brick patio and use a broom to sweep the sand into the cracks between bricks. Apply more sand as necessary to make the sand between the bricks flush with the top surface of each brick.
Use a wheelbarrow to more easily cart soil and sod away from your work area.
