How to Edge a Brick Patio
A brick patio can be edged after the installation of the patio itself or even before the installation. There are many ways to edge a patio and this can be done to give it accent. The patio can be edged with paver bricks before or after installation or with any other edging material after installation (e.g. gravel edging, timber, etc.).
Step 1- Determine What Type of Edging Material to Use
The best way to edge a brick patio is to edge it with bricks as well. However, the bricks should be paver bricks. For better drainage options, edging with pea gravel is a good choice. Timber can also be used as an edging material to provide an alternative look for the patio.
Step 2 – Edging with Bricks
Dig a trench around the perimeter of the patio area about 6 inches deep. Fill the trench with sand to allow the bricks to be at least 1 to 2 inches above ground. If the patio is already installed, make sure that the brick edging is level with the other bricks. Use a rubber mallet to drive the paver bricks into the sand. Lay the edging on the perimeter end to end until the entire edging frame is complete. Fill the joints with the concrete mix. Sprinkle the edging with water and let it set.
Step 3 – Edging with Pea Gravel
Pea gravel is an excellent edging material. Plan out how the gravel is to be set around the perimeter of the patio. The edging can be rectangular in shape or its outer edge can have any other geometric design pleasing to the eye. When the design is set, remove at least 4 to 6 inches of the topsoil around the perimeter of the patio. Pour the gravel into the trench. Level the gravel with a wooden board or any other stiff board.
Step 4 – Edging with Timber
Timber looks very nice after installation but this type of edging may not last the longest because it can rot after a couple of years. However, it is a pretty alternative for people who love to try the idea. First of all, dig a trench around the patio deep enough to allow the top surface of the timber to be level with the height of the patio. The trench must be allowed to slope away from the patio to ensure proper drainage.
Measure the required length of timber to completely cover the perimeter. Purchase the timber and have it cut to the correct dimensions. Make sure that the timber pieces are square and straight to avoid having installation problems.
Drill ½-inch diameter holes at least 2 inches deep every 3 feet on the middle portion of the underside of the timbers for the rebar supports. Insert the rebar supports into the timber. Position the timber above the trench and allow the rebar supports to pierce into the ground holding the timber edging in place.
