Guides

The calculators work out how much material your job needs. These guides answer the questions that come either side of that: what the stuff weighs, how to read a supplier's quote when it is priced by the ton, what it should cost, and how deep it has to go to actually work. Every figure comes from the same density table the calculators use.

Looking for the numbers rather than the explanation? The how we calculate page has every formula and density with its source, and bags per cubic yard has the full bag-count reference. Otherwise, head straight to all calculators.
