  • Results depend on the numbers you enter and on assumptions such as weight per cubic yard, which vary by product, moisture and region.
  • Building codes change and differ from place to place. Where a page names a code or a regulation, it names the edition we read and says that local rules govern.
  • The calculators do not design structures. They do not size beams, joists, footings or reinforcement, and they do not replace advice from a qualified professional.
  • If you rely on a result, you do so at your own risk. See the terms of use.
