How much stone base material and sand setting bed material I need?
One half ton of modified stone or sand will cover about 100 square feet at 1 thick. Using a 10′ x 10′ (100 square feet) patio as an example, you would need 1/2 ton of sand for the setting bed (1 thick) and 3 tons of modified stone for the base (6 thick). You’ll need about 5% more sand for the joints between the pavers. The thickness of the base material depends on the application and subgrade soil conditions (use a thicker base for poorly drained soils). As a rule of thumb, youll need 4 to 8 of base material for walkways and patios, and 8 to 12 for driveways and parking areas.
