Weights used

The weights per cubic metre are typical figures and fill in automatically when you choose a material. Wet or compacted material weighs more, so change the figure if your supplier gives a different one. Bulk bag sizes also vary between suppliers.

These are estimates for planning and ordering. Materials, bag sizes and densities vary by product, so always check the figures on the packaging or with your supplier before you order. For structural work, follow the advice of a qualified builder or engineer.
