How do I detennine how much modified stone base material and sand Ill need?
As a rule of thumb, use a minimum of 3″-5″ of base material for walkways, 6″-8″ for patios, and 8″-12″ for driveways. The sand setting bed should be 1″ thick. One ton of modified stone or sand will cover 100 square feet at 2″ 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 some additional sand (about 5%) or two bags of EP Henry PolySand for the joints between the pavers.
