Difference Between a Foundation and Footing

The difference between foundation and footings are

Foundation
  • A foundation is the lower portion of a building structure that transfers the building load into the earth.
  • A strong foundation is required in order for a building to stand the test of time and survive for decades or even centuries.
  • Foundations are commonly separated into two categories:
    • Shallow foundations
    • Deep foundations
  • Building foundation is made by first digging a trench into the ground. Dig deep enough to reach the subsoil.
  • Concrete is then poured into the trench, supported and strengthened further with steel rods. When the concrete dries the steel holds it all together.
  • This is a reinforced concrete and once it is in place, the structure can be built on top.
  • Footing includes slab, rebar which are fabricated of brickwork, masonry or concrete.
  • Footing reinforces support to an individual column.
Footing
  • A footing is a foundation that is constructed under the base of a wall or a column.
  • Purpose of the footing is to distribute the weight of the building over a large area. The term footing is generally used in conjunction with shallow foundations not deep foundations.
  • Footing is placed directly below the lowest part of the structure it supports.
  • Foundation types include piles, caissons, footings, piers the lateral supports and anchors.
  • Foundation is an extensive support because it gives support to a group of footings as an entire building.
