Multiply length (ft) x width (ft) x depth (ft) for cubic feet. Divide by 27 for cubic yards.
Frequently Asked Questions
How deep should footings be?
In cold climates, footings must sit below the frost line (300 mm in mild zones up to 1200 mm in severe frost areas). In frost-free regions, 300-450 mm (12-18 in) is typical. Standard width is twice the wall width. Always check local building codes.
