Foundation Construction
We handle the construction of foundations, which provide the structural support for the building. This may involve pouring concrete footings, laying foundation walls, and installing necessary drainage systems.
What is a Foundation in Construction
Foundation is the lowest part of the building or the civil structure that is in direct contact with the soil which transfers loads from the structure to the soil safely.Generally, the foundation can be classified into two, namely shallow foundation and deep foundation
Shallow foundation
A shallow foundation transfers the load to a stratum present in a shallow depth.
Deep foundation
A tall building like a skyscraper or a building constructed on very weak soil requires deep foundation. If the constructed building has the plan to extend vertically in future, then a deep foundation must be suggested.
The foundation for each structure is designed such that:
- The underlying soil below the foundation structure does not undergo shear failure
- The settlement caused during the first service load or have to be within the limit
- Allowable bearing pressure can be defined as the pressure the soil can withstand without failure.
Purpose of Foundation
Foundations are provided for all load carrying structure for following purposes:
- Foundation are the main reason behind the stability of any structure. The stronger is the foundation, more stable is the structure.
- The proper design and construction of foundations provide a proper surface for the development of the substructure in a proper level and over a firm bed.
- Specially designed foundation helps in avoiding the lateral movements of the supporting material.
- A proper foundation distributes load on to the surface of the bed uniformly. This uniform transfer helps in avoiding unequal settlement of the building. Differential settlement is an undesirable building effect.
- The foundation serves the purpose of completely distributing the load from the structure over a large base area and then to the soil underneath. This load transferred to the soil should be within the allowable bearing capacity of the soil.
Functions of Foundation in Construction
Based on the purposes of foundation in construction, the main functions of the foundation can be enlisted as below:
- Provide overall lateral stability for the structure
- Foundation serve the function of providing a level surface for the construction of substructure
- Load Distribution is carried out evenly
- The load intensity is reduced to be within the safe bearing capacity of the soil
- The soil movement effect is resisted and prevented
- Scouring and the undermining issues are solved by the construction of foundation
