Mat Slab Foundations Definition

The construction of mat foundation.

Mat slab foundations definition.

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. Raft foundation is also known as a mat foundation. It is common to use mat foundation or deep basements to transfer the column loads to the underlying soil as well as provide floor slab for the basement. 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.

It is considered as one type of shallow foundation and is useful in controlling the differential settlement. A slab foundation is a large thick slab of concrete that is typically 4 6 thick in the center and poured directly on the ground all at one time. A shallow foundation is a type of building foundation that transfers building loads to the earth very near to the surface rather than to a subsurface layer or a range of depths as does a deep foundation shallow foundations include spread footing foundations mat slab foundations slab on grade foundations pad foundations rubble trench foundations and earthbag foundations. Raft foundation is the essentially continuous slab which is resting on the hard soil which extends over the entire building footprint.

It declines the contact pressure in comparison with conventional strip or trench footing. Raft mat foundation is used in those places where we have less bearing capacity of the soil. A mat foundation spreads out under. Mat foundation is constructed as a large slab which works as the base for the building.

Many foundations utilize post tension cables while others are reinforced with. A mat foundation is used when the subsoil is weak and column loads are so heavy that the conventional spread footings cover more than 50 of the building area. Usually mat foundation is spread over the entire area of the structure it is supporting. Raft foundation is actually a thick concrete slab resting on a large area of soil reinforced with steel supporting columns or walls and transfer loads from the structure to the soil.

The building then rests on this foundation leading to lesser contact with the land and hence more strength and stability.
