Concrete calculations, clearly explained

Concrete volume starts with the finished dimensions of the space you need to fill. Slabs use length × width × depth, while footings, piers and post holes use shapes suited to their geometry.

Order quantities usually include a small waste allowance for uneven excavation, spillage and variations in subgrade. Always confirm delivery minimums and mix requirements with your supplier.
