Mat foundations 10 1 introduction a mat foundation is a large concrete slab used to interface one column or more than one col umn in several lines with the base soil.

The bearing capacity increased by combining all individual footings in to one mat since bearing capacity is proportional to width and depth of foundations. Hydrostatic uplift resistance is needed etc. 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. Mat foundation often considered to be used when dealing with the following conditions.

The spread footings cover over 50 of the foundation area because of large column loads. Mat or raft foundation is a large concrete slab supporting several columns in two or more rows. 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. Although mat foundations are more difficult and more costly to design than individual spread footings they can be used effectively.

Syeda khushnuma wasim 1316011 3. Mat foundations are sometimes preferred for soils that have low load bearing capacities but that will have to support high column or wall loads. Sohanur rahman prince 1316006 2. Presentation on mat foundation 1.

Presentedby name md. Abu bakar siddik sabrina mehenaz tanvir alam khan md. The soil is soft with a low bearing capacity. It is used where the supporting soil has low bearing capacity.

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.
