Mat Foundation Vs Spread Footing

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.

Mat foundation vs spread footing.

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. Raft mat foundation is used in those places where we have less bearing capacity of the soil. It is circular square or rectangular slab of uniform thickness.

Sometimes it is stepped to spread the load over a larger. In such a case it is more economical to provide a strip footing than to provide a number of spread. Mat or raft foundation. Mat or 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 footing is under the foundation wall. 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. A number of footings repose on a foundation.

Mat foundations are sometimes preferred for soils that have low load bearing capacities but that will have to support high column or wall loads. Foundations are the basement walls. Under some conditions spread footings would have 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.

All footings are foundations. This footing is used to. 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. Foundation is the support that bears all kinds of loadings.

Although mat foundations are more difficult and more costly to design than individual spread footings they can be used effectively. Mat foundation raft foundation it is a combined footing that may cover the entire area under a structure supporting several columns and walls. Foundation is in direct contact with the soil and transmits it to the ground. A strip footing is provided for a load bearing wall.

Furthermore mat footings are helping to reduce the varying settlements caused by construction on non homogenous soils or uneven load distribution on the footing.
