Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Main slab volume = length × width × thickness. Thickened-edge volume uses the perimeter band area × extra depth. Allowance is added before bag rounding.
FAQ
Concrete Driveway Calculator questions
Does the edge calculation double-count the corners?+
No. It subtracts the inner rectangle from the overall rectangle to obtain one continuous perimeter band.
How thick should a driveway be?+
Thickness depends on soil, base, reinforcement, vehicle loads and local practice. Use an approved project specification.
Are control joints optional?+
Joint layout is an important crack-control detail. The displayed quantity is only a spacing guide, not a complete joint design.
