Build a Raised Patio with Brick Pavers Build a Raised Patio with Brick Pavers
A raised patio is often used if you want the patio floor to be at the same level as the house floor from which it is accessed.
Step 1 - Mark the Floor Area for the Patio
Clearly mark the floor area of the patio. Use lines tied between stakes hammered into the ground. Ensure that you mark the floor area precisely.
Step 2 - Dig the Footings
The patio will require a retaining wall. Dig a trench to the required depth for the footings and compact the bottom. Follow the lines to ensure the trench is straight and the corners square.
Step 3 - Level the Trench Bottom
Use a long straight piece of wood and a level to make sure the bottom of the trench is level.
Step 4 - Damp proofing
Line the trench with a waterproof membrane and carry it over onto the patio area.
Put between 4 to 6 inches of concrete into the trench on top of the membrane and level it. Pour enough self leveling cement onto the concrete after it dries to create a perfectly horizontal surface. Allow it to dry thoroughly.
Step 5 - Build the Retaining Wall
The retaining wall can be built directly onto the concrete base. Use guide lines to ensure that every course is level and the lines are straight. A single-brick thickness is enough for a low wall but higher walls will require greater thickness.
Step 6 - Prepare Patio Area
When the wall is at the required height, let it dry for a day or so. Fold the waterproof membrane back over the wall. Dig out the patio area surface to make a firm base for the patio. Compact the surface as much as possible. Bring the waterproof membrane back over the patio area.
Step 7 - Fill Surface Lines
Cover the surface with about 3 inches of well-mixed fine gravel and sand. Level this off, using a straight piece of wood and a level. The surface should be firm and well-compacted so that when you walk on it you do not leave foot prints.
Step 8 - Lay the Pavers
Starting in one corner, put a layer of sand about 1 inch deep on top of the base. Smooth and level the sand. Position the first patio paver against the retaining wall and slide it carefully snuggly into the corner. Tap the paver down, using a rubber mallet. Use a level to make sure the paver is horizontal. Using this paver as a guide and working in 1 small area at a time, lay the rest of the pavers.
Step 9 - Fill Paver Spaces
Pour a pile of sand onto the pavers and sweep it around until all the gaps are filled then remove the excess.
Your patio is now ready but you can add finishing touches by building a retaining wall or a balustrade around the patio.
