A strip foundation is a type of shallow foundation used to support load-bearing walls. It consists of a continuous strip of concrete that distributes the weight of the structure evenly across the ground. This foundation is typically used in residential buildings and is suitable for stable soil conditions. The construction of a strip foundation involves excavating a trench where the foundation will be placed. The trench is then filled with concrete, creating a solid base for the walls. This method is cost-effective and efficient, making it a popular choice in the construction industry, especially for smaller buildings.
