Piles are also used to resist bending as well as horizontal forces. It is possible to hammer such piles only with the use of a special pneumatic hammer, which is very expensive to use in private housing construction. The types of deep foundations in general use are as follows: A Pile foundation is defined as a type of deep foundation that comprises a long, slender column used to transfer the load coming from the superstructure to the lower-lying ground thereby providing overall support to the structure. This can lead to a loss of bearing capacity. Concrete piles are the type of pile foundation that essentially consists of concrete as the chief element. Can break while driving. In case the columns in a row are nearer or if the SBC of soil is low, the continuous footing will be more applicable. Fence posts
Diagram of the strip brick foundation device. Reinforcing bars add tensile property to the foundation making the whole structure capable of withstanding tension and compression affect.
