Install interlocking pavers by excavating the area to be paved, preparing the base before installing the edge restraints and screening the bedding sand. Cut and lay the pavers, and set the pavers with masonry sand.
Prepare the area for the pavers by excavating the surface to a depth of at least 7 to 9 inches. Slope the area away from the home, and add a processed gravel base to provide a firm foundation for the pavers. Use at least 5 inches of crushed stone or aggregate, wetting it lightly to compact it. Install edge restraints to keep the pavers from shifting, making sure all the corners are exactly 90 degrees.
Add a layer of sand over the crushed stone. Screen the sand so it is level, and pack the sand around the edge railing to hold it in place. Fill in any low spots with extra sand.
Beginning in a 90-degree corner, lay the pavers in the pattern you selected. Leave a 1/8-inch space between the pavers, and cut the pavers as needed to fit the design. Sweep masonry sand over the pavers, tamping excess sand into the joints to set the surface. Use a plate compactor to tamp the pavers down, and resweep the pavers with masonry sand over the next few days until it is compacted into the joints.
