Mat Type Foundation

Mat foundation also known as a raft foundation or floating foundation is a way of giving extra support to a building.

Mat type foundation. Additionally to the raft is made to improve the flexural stiffness of the foundation. Soil type building load and environment to name a few. One reason is if the soil on which the building is constructed does not have a bearing capacity. How to construct a raft or mat foundation a raft foundation is constructed by first excavating the ground to a uniform flat level.

The categorization of the mat foundations is made based on the modifications made to the flat plate.

The weight of the building is spread evenly over the entire footprint of the building. Factors on which footing types depends are bearing capacity of the soil. Types of mat foundation. The type of superstructure is going to construct.

The load applied from structure to the 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.
