Broadly, foundations provide support and anchor the superstructure of a building, helping transfer the load directly to the earth prepared with suitable settlement characteristics and sufficient bearing capacity.

Foundations are categorised as deep and shallow foundations. A deep foundation is used where the bearing capacity of the soil is not sufficient to support the building’s structure. In contrast, a shallow foundation is used where the structure load is low compared to the bearing capacity of the soil or ground.

What is a Strip Foundation?

• A strip foundation, also called strip footing, is a kind of shallow foundation.
• It supports linear structures such as walls built on the foundation.
• Though it runs beneath all the bearing walls, the strip’s width is determined by the bearing load and pressure of the ground.
• The strip’s width should be long enough to lay on solid ground.
• Furthermore, the soil’s quality also plays a role in determining the depth of the foundation.

Where is Strip Foundation Suitable?

A concrete strip foundation is suitable where the soil has an excellent bearing capacity and quality. It is used in light structural buildings such as medium-rise domestic buildings.
