What is site investigation? Soil is made by nature and often used for foundation in its natural state. Unlike steel or concrete the properties of soil cannot be controlled and must be used as they exist. As a result the engineers are compelled to control the loading conditions. In order to provide loading conditions that will not exceed the carrying capacity or allowable deformation, the extent and properties of soil must be determined prior to the design of the foundation. The information can only be obtained through a properly planned…

Types of Foundation | Shallow and Deep
What are the types of foundation? On the basis of load transmission to the ground, there are two types of foundation and they are: Shallow foundations and Deep foundations. As we know foundation connects/interfaces two different materials, their strength ratios are of the order of several hundreds. As a result, the load may be spread to the soil in a manner such that its limiting strength is not exceeded and the resulting deflections are tolerable. Description of various types of foundation is given below. SHALLOW FOUNDATION In shallow foundation, generally,…

What is foundation or Sub-Structure? In any structure the lowest part is called foundation or sub-structure. In general cases, structures comprise two parts: upper part and lower part. The part lying above the ground surface is upper part where as the part buried below the ground surface is lower part. Being the portion above the ground surface, the upper part is called super-structure while the lower part, the sub structure or foundation. The foundation acts as an interface between the super-structure and that part lying under the soil. Therefore the…
