Methodology

Transparent calculation

BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.

Compacted volume = length × width × depth. Loose order volume applies the entered allowance, then density converts volume to weight. Truckloads and fabric rolls round up.

FAQ

Gravel Parking Pad Calculator questions

Why add a loose-material allowance?+

Delivered aggregate contains voids and compacts after placement, so loose order volume commonly exceeds finished volume.

Does every parking pad need fabric?+

No. Fabric use depends on subgrade, drainage, aggregate layers and design goals.

Is one gravel layer enough?+

Not always. Many pads use different base and surface aggregates, which should be estimated separately.
