Mat Foundation Vs Spread Footing

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.

Mat foundation vs spread footing.

Mat foundation raft foundation it is a combined footing that may cover the entire area under a structure supporting several columns and walls. 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. All footings are foundations.

Mat or raft foundation. Foundation is in direct contact with the soil and transmits it to the ground. A number of footings repose on a foundation. Footing transmits loads directly to the soil.

A strip footing is also provided for a row of columns which are so closely spaced that their spread footings overlap or nearly touch each other. Mat or raft foundation. A footing is under the foundation wall. 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.

This footing is used to. 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. Under some conditions spread footings would have to. It is circular square or rectangular slab of uniform thickness.

Foundations are the basement walls. 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. In such a case it is more economical to provide a strip footing than to provide a number of spread. Mat footings are used when the building load is so high that spread or strip footings could not bear the weight or their employment would be inefficient.

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 mat foundation is used in those places where we have less bearing capacity of the soil. 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. Sometimes it is stepped to spread the load over a larger.

Although mat foundations are more difficult and more costly to design than individual spread footings they can be used effectively.
