THIS PICTURE SHOWS FOUNDATION AT THE BOTTOM
SOMETHINGS I FOUND ON THE NETFoundations, sometimes called footings or the substructure, are designed to support the walls and the roof and to provide a solid base on which to build the house. The type of foundation chosen will depend on two distinct variables: the total building loadStrip foundations are the most common type used because they offer good strength for their cost. They are created by excavating a trench deep enough to avoid damage to the foundation caused by changes in the topsoilThere are three types of strip foundation - traditional shallow strip, as described above, wide strip, used when the load of the structure is high relative to the weight bearing capacity of the subsoil and deep strip (also known as trenchfill foundations). Wide strip foundations are laid in exactly the same way as standard strip foundations except that the trench is much wider and reinforcement is frequently used to economise on concrete.
