Tips for Accurate Measurements

Frequently Asked Questions
How many pavers do I need per square foot?
It depends on paver size. 4"×8" pavers need about 4.5 per sq ft. 6"×6" need 4 per sq ft. 12"×12" need 1 per sq ft.
How much sand do I need under pavers?
Use 1 inch of sand as a leveling bed over compacted gravel. Too much sand (over 1.5") causes pavers to shift.
Do I need a gravel base?
Yes, install 4-6 inches of compacted gravel base for proper drainage and stability. This prevents settling and frost heave.
How much waste should I factor in?
10% waste is standard for straight patterns. Add 15-20% for diagonal or complex patterns with many cuts.
