Raft Or Mat Foundation

Raft or mat foundations a raft foundation also called a mat foundation is essentially a continuous slab resting on the soil that extends over the entire footprint of the building thereby supporting the building and transferring its weight to the ground.

Raft or mat foundation.

Flat plate type raft. It is also called as mat foundation which are widely used foundation system. A raft or mat foundation is a large continuous rectangular or circular concrete slab that carries the entire load of the superstructure and spreads it over the whole area beneath the building. Raft mat foundation is used in those places where we have less bearing capacity of the soil.

Mat foundations are sometimes preferred for soils that have low load bearing capacities but that is going to need to support high wall or column loads. Raft foundation is mat foundation now what is raft foundation. At those places we use mat foundations to distributes the whole loads of the structure to the soil when the area of the footing was increase than the soil load bearing capacity will also increase because this foundation reduces the stress on the soil at the same place. A mat foundation spreads out under.

Raft foundation is a thick concrete slab reinforced with steel which covers the entire contact area of the structure like a thick floor. Raft foundation is also known as mat foundation. When the raft foundation is supported on piles it is called a piled raft. Raft foundation is a type of shallow foundation.

Raft foundation is a thick reinforced concrete slab which spreads over a large area of soil and provides support for several columns and load bearing walls. Raft foundation is the essentially continuous slab which is resting on the hard soil which extends over the entire building footprint. Don t confuse about raft and mat foundation.

The mat foundation which is sometimes known as a raft foundation is a combined footing that could cover the whole area under a structure supporting several walls and columns. Raft foundations sometimes referred to as raft footings or mat foundations are formed by reinforced concrete slabs of uniform thickness typically 150 mm to 300 mm that cover a wide area often the entire footprint of a building. Raft foundation is also known as a mat foundation. It declines the contact pressure in comparison with conventional strip or trench footing.
