Frequently Asked Questions
How do I calculate how many pavers I need?
Divide the total project area in square feet by the area of a single paver in square feet. A standard 4x8 inch paver covers 0.222 square feet, so a 100 square foot patio needs about 450 pavers. Add 10% for cuts and waste.
How much sand do I need under pavers?
You need two layers of sand: a 1-inch leveling layer of bedding sand on top and a 4-6 inch compacted gravel base underneath. For the sand layer, plan about 1 ton per 120 square feet at 1-inch depth. Polymeric sand is used to fill joints after laying.
How deep should the gravel base be for pavers?
A 4-inch compacted gravel base is standard for patios and walkways. Driveways need 6-8 inches of compacted gravel to support vehicle weight. The base should extend 6 inches beyond the paver edge on all sides.
What waste percentage should I plan for pavers?
Plan for 5-10% waste for rectangular layouts and 10-15% for curved or angled designs that require more cutting. Complex patterns like herringbone may produce slightly more waste than running bond. Buy all pavers from the same lot to ensure color consistency.
