Mat Foundation Vs Spread Footing

Foundations are the basement walls.

Mat foundation vs spread footing.

Raft mat foundation is used in those places where we have less bearing capacity of the soil. Mat or raft foundation. A number of footings repose on a foundation. 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.

Footing transmits loads directly to the soil. A footing is under the foundation wall. Footings can be of the following types. Spread or isolated or pad footing strap footing combined footing strip or continuous footing mat or raft footing what is spread footing or isolated or pad footing.

All footings are foundations. The isolated footing is commonly used in reinforced cement concrete columns because it very is simple and most economical as compared to the other footings. Foundation is in direct contact with the soil and transmits it to the ground. Mat foundation raft foundation it is a combined footing that may cover the entire area under a structure supporting several columns and walls.

Mat foundations are sometimes preferred for soils that have low load bearing capacities but that will have to support high column or wall loads. Foundation is the support that bears all kinds of loadings. A mat foundation also may be used to resist hydrostatic pressures or to bridge over small soft spots in the soil provided the mat is adequately reinforced. Furthermore mat footings are helping to reduce the varying settlements caused by construction on non homogenous soils or uneven load distribution on the footing.

A strip footing is provided for a load bearing wall. Under some conditions spread footings would have to. Although mat foundations are more difficult and more costly to design than individual spread footings they can be used effectively. This footing is used to.

It is circular square or rectangular slab of uniform thickness. Mat or raft 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. 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.

In such a case it is more economical to provide a strip footing than to provide a number of spread.
