Why Big-Box Store Calculators Cost You Money
Most online calculators use oversimplified textbook geometry (L × W × H) that leaves you 5 bags short on pour day—or stuck hauling 800 lbs of extra gravel back to the store.
True Volume Displacement
Our French Drain and Post Hole calculators automatically subtract the physical volume taken up by 4" corrugated pipe (4.3" OD) and submerged nominal lumber (3.5" × 3.5" for a 4×4 post).
Exact US Retail SKU Yields
We convert raw cubic feet directly into standard American supply house packaging: 80 lb (0.60 cu ft), 60 lb (0.45 cu ft), and 50 lb Fast-Setting bags, plus Ready-Mix truck break-even alerts.
Compaction & Waste Factors
Crushed #57 and #411 paver base compresses by 12–15% under a plate compactor, and epoxy resin loses volume to mixing cup walls. Every tool includes one-click jobsite waste toggles.
