Construction of Wall Footing

Reading time: 1 minute

Wall footings are pad or spread and strip footings which are used to support structural or nonstructural walls to transmit and distribute the loads to the soil in such a manner that the load-bearing capacity of the soil is not surpassed. In addition to avoiding excessive settlement and rotation and maintain sufficient safety against sliding and overturning.  

Wall footing runs along the direction of the wall. The size of the footing and the thickness of the foundation wall are specified on the basis of the type of soil at the site. The width of the wall footing is generally 2-3 times the width of the wall.

The wall footing can be constructed from stone, brick, plain concrete, or reinforced concrete. Economical wall footing can be constructed provided that the imposed load needed to be transmitted are of small magnitude and the underlying soil layer is of dense sand and gravels. Therefore, wall footing is best suited for small buildings.

3. Reinforced Concrete Wall Footing

If the load on the wall is heavy or the soil is of low bearing capacity, reinforced concrete strip footing can be provided.

The thickness of the strip can be reduced towards the edge to effect economy.
