Building a patio allows you to have another way to enjoy your backyard on a nice day. The solid surface of the patio provides a firm, dry surface where you can place your grill and patio furniture and a place for you and others to stand when the ground is muddy or wet. One material you can use when building the patio is brick. Brick is durable and fairly easy to install and has a traditional style that many people find appealing.
Mark the perimeter of the patio by driving wooden stakes into the ground or spraying the grass with spray paint.
Excavate the ground inside the perimeter outline. Dig the hole for the patio deep enough to accommodate 6 inches of gravel, 1 inch of sand and the height of the bricks. In this example, we'll say the bricks are 3 inches high, so the hole needs to be 10 inches deep. When digging the hole, slope it away from the house at a slight angle for drainage.
Lay landscaping fabric over the soil in the hole to prevent weeds from growing through the bricks.
Add a layer of gravel over the landscaping fabric that is 3 inches deep. Rake the gravel smooth, and spray it lightly with a hose to reduce dust. Tamp the gravel down to compact it.
Add a second 3-inch-deep layer of gravel over the first layer. Rake the gravel smooth, and spray it lightly with a hose to reduce dust. Tamp the gravel down to compact it.
Add a 1-inch layer of sand on top of the gravel. Screed the surface of the sand by dragging a 2-by-4 board across the top with a side-to-side motion. Fill any low spots exposed by the screeding with sand, and screed the surface again.
Install the edge restraints. This is a product that is installed along the edge of the hole that prevents the bricks from shifting. Installation methods vary by manufacturer, but generally you place the restraints against the sides of the hole and drive metal stakes provided with the restraints through holes in the restraints and into the ground.
Begin laying the bricks on top of the sand. Stagger the bricks when laying them to make the patio stronger. Use a wet saw to cut bricks when necessary. Set the bricks until the patio is complete.
Spread fine-grit sand over the bricks. Sweep the sand into the gaps between the bricks.
Run over the bricks with a mechanical compactor. Sweep the remaining sand into the gaps between the bricks.
Remove any leaves, twigs and other debris from the patio.
Apply a sand-binding sealant to the bricks, following the instructions on the packaging.
