Frequently asked questions

How many pavers do I need for a patio?
Divide the patio area (ft²) by the area of one paver (ft²), then add 10% for waste. For example, a 192 ft² patio using 12×6 inch pavers needs about 423 pieces.
What size base do I need under pavers?
Lay a 4–6 inch compacted gravel base, then a 1-inch sand screed layer. This provides drainage and a level surface for paver installation.
