Footings

A column footing is usually a block of concrete poured in the bottom of a hole so that the weight placed on the column can be distributed through a larger area. This helps prevent columns from sinking into the ground over time.
Footings can be of the following types.

  • Spread or isolated or pad footing.
  • Strap footing.
  • Combined footing.
  • Strip or continuous footing.
  • Mat or raft footing.

A structure needs a foundation that supports it. The term footing is used in conjunction with shallow foundations commonly. A footing is a foundation unit constructed in brick work, masonry or concrete under the base of a wall or a column for the purpose of distributing the load over a large area.

Footings
Footings are an important part of foundation construction. They are typically made of concrete with rebar reinforcement that has been poured into an excavated trench. The purpose of footings is to support the foundation and prevent settling. Footings are especially important in areas with troublesome soils.
