Demolition of concrete, dirt, or asphalt. Minimum excavation depth of -7.5" for vehicular traffic and a minimum of -5.5" for pedestrians.
Grade sub-base to ensure to ensure proper drainage requirements. Install drain lines where applicable.
Import class 2 road base and compact to 95% of the Maximum Standard Proctor Density (ASTM D698). Minimum of 4" for vehicular traffic and 2" for pedestrian. Install geotextiles if necessary.
Sand is installed over the base to a consistent thickness between ¾ inch (20 mm) and 1½ inch (40 mm) according to ICPI guidelines (ASTM C33).
Install paving stones in the chosen type, size, color, and pattern.
Install edge restraints around the perimeter of the pavers. They are essential for eliminating horizontal creeping of the pavers and loss of bedding sand. They hold the pavers in place for the life of the pavement.
Pavers are then compacted without joint sand to create initial interlock. After this is complete, dry joint sand is spread and swept and then the pavers are compacted again until the joints are completely full.
While pavers are extremely durable, sealing is optional. Sealing can enhance the colors, help prevent staining, and reduce loss of joint sand.
