Concrete Footing Definition

Every structure has a foundation, and under most foundations are footings to distribute structural loads from the building to the ground. If the load of the building is not distributed properly, settling is likely to incur. Calculating the size of the footing is a critical element in the building process and must be done early to ensure the integrity of the construction.

The concrete footing calculator allows you to enter the following dimensions of your footing:

  • Depth
  • Width
  • Length

Concrete is calculated in cubic yards. After submitting your dimensions, the overall concrete needed for your project will be calculated ensuring the exact cubic yards for your footings.
