Having a brick patio creates a nice seating area for friends and family. However, if it is old, it can be unlevel. This potentially unsafe situation should be addressed. In most cases, the issue is due to the approximately one inch of sand that lies under the bricks. Redistributing the sand should level the patio, providing an enjoyable socializing area for many years.
You will need:
Step 1: Select a material staging area that is convenient to the patio but not in the way of this work area.
Step 2: Begin removing the bricks, starting at an edge or corner. If you have trouble, insert the screwdriver in a space between two bricks and tap it with the rubber mallet to widen the gap and remove the brick. Work from one end to the other until all of the bricks have been removed, storing each one in the staging area.
Step 3: Add some sand to the problem areas of the patio but do not add all the sand at one time. Additional sand may be required during the later leveling stage.
Step 4: Take the two steel pipes and put them in the sand at a slight downward angle toward the edge of the patio, for drainage purposes. Begin leveling the sand with the 2×4, using the pipes as guides. Add sand as needed. The trowel can be used to level areas that the 2×4 cannot reach.
Step 5: Place the bricks, starting from one corner and working out to another. Place each brick up against another to ensure a secure fit.
Step 6: Spread some of the leftover sand over the bricks. With the broom, sweep this sand over all cracks between bricks. Repeat this step following the next heavy rainstorm to make sure the area is level.
