What is ordinary strip foundation?

Answer 1

Load Distribution: The primary function of a strip foundation is to distribute the load from the building's walls evenly to the underlying soil. This prevents excessive settlement or soil bearing capacity issues.

Width and Depth: The width and depth of a strip foundation depend on factors such as the building's load, the type of soil, and local building codes. The width is typically greater than the width of the wall it supports. The depth is determined by the frost depth (to prevent frost heave) and the soil's bearing capacity.

Reinforcement: In some cases, steel reinforcement bars (rebar) may be added to the concrete strip to enhance its tensile strength and overall stability.

Footing Dimensions: The footing, or the bottom part of the strip foundation, is wider and serves as the load-spreading element. It is usually wider than the wall it supports to provide stability.

Construction Process: Strip foundations are typically cast directly on the ground or on a shallow trench. The trench is excavated to the required depth and dimensions, and then concrete is poured into the trench to create the foundation.

Use in Residential and Light Commercial Buildings: Strip foundations are commonly used in residential buildings, small commercial structures, and other low- to medium-rise buildings. They are suitable for structures with relatively light loads.

Cost-Effective: Strip foundations are cost-effective and relatively simple to construct, making them a popular choice for a wide range of building types.

Answer 2

This type of foundation is centrally placed under the walls and is generally composed of plain concrete to a mix of 1:3:6 by volume (cement, fine aggregate and coarse aggregate). Internal walls may be supported by separate strip foundation or by thickening the concrete over-site.
