- Basement Foundation.

What is the main purpose of building foundation?
Foundations provide support for structures, transferring their load to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics to support them.
What is the cheapest foundation for a house?
Concrete Slab Cost Concrete slabs are generally the cheapest type of foundation to install. Because they’re built slab-on-grade, they don’t require much excavating or ongoing maintenance, and they typically don’t promote moisture problems.
What are the 3 purposes of foundation?
Foundation Functions The three most important are to bear the load of the building, anchor it against natural forces such as earthquakes, and to isolate it from ground moisture. The relative importance of these functions changes with the type of land underneath the building and the building design.
What is the importance of a foundation?
Why do we need foundations?
In general terms, foundations ensure that the load of a building is spread evenly over the ground underneath the building. Finally, foundations anchor the building to prevent its moving sideways when, for example, it is built on sloping ground.
What are the functions of a foundation in a building?
Foundation is the lower portion of the building usually located below ground level, which transmits the loads of the super structure to the supporting soil. A foundation is therefore that part of the structure which is in direct contact with the ground to which loads are transmitted. 1. Reduction of load intensity
What should I use to build a foundation?
The construction of the foundation can be done with concrete, steel, stones, bricks etc. The material and the type of foundation selected for the desired structure depends on the design loads and the type of underlying soil.

What kind of foundations are used in basements?
Raft Foundations, also called Mat Foundations, are most often used when basements are to be constructed. In a raft, the entire basement floor slab acts as the foundation; the weight of the building is spread evenly over the entire footprint of the building. It is called a raft because the building is like a vessel that ‘floats’ in a sea of soil.

Generally it is below the ground level. If some part of foundation is above ground level, it is also covered with earth filling.
What is the function of a foundation of a building?
Functions of Foundation Reduction of load intensity. Foundation distributes the loads of the super structure, to a larger area so that the intensity of the load at its base (i.e. Even distribution of load. Foundations distribute the non-uniform load of the super structure evenly to the sub soil. Provision of level surface. Lateral stability. Safety against undermining.
What is the purpose of foundation in building construction?
Foundations are buried in the ground and hold buildings up. The purpose of a foundation is to hold up and hold together the structure above it . Contrary to our everyday experience the ground is not quite still and in many cases not totally solid.
What is the strongest foundation?
