Comment calculer Pavers
Pavers: Paver area (sq ft) = (width × length) ÷ 144. Pavers = area ÷ paver area × 1.05 (5% waste pour cuts).
Base gravel: Cubic yards = area × (base depth ÷ 12) ÷ 27. Compacted base reduces volume ~15%.
Sable bedding: Cubic yards = area × (sand depth ÷ 12) ÷ 27. Use coarse sand, not play sand.
