Mat Type Foundation

The depth of the soil at which safe bearing strata exists.

Mat type foundation.

Two common foundations that are for very different uses are mat foundations and pile foundations. Additionally to the raft is made to improve the flexural stiffness of the foundation. Soil type building load and environment to name a few. Raft or mat foundation the use of mat foundation is for columns and walls foundations where the loads from the structure on columns and walls are very high.

There are many reasons why mat foundation is chosen by builders across the globe. The depth of the raft foundation is manly increased at column positions to carry the high bending moments and shear forces. We would like to show you a description here but the site won t allow us. This type of foundation is suitable for loose soil.

Since this soil is not able to support the building on its own a mat foundation is built. How to construct a raft or mat foundation a raft foundation is constructed by first excavating the ground to a uniform flat level. Raft or mat foundations are the types of foundation which are spread across the entire area of the building to support heavy structural loads from columns and walls. The categorization of the mat foundations is made based on the modifications made to the flat plate.

Factors on which footing types depends are bearing capacity of the soil. In the cellular mat foundation the structures of boxes are formed and walls of every box act as beams. The type of superstructure is going to construct. Types of foundations or footings.

It is called a raft because the building is like a vessel that floats in a sea of soil. It is also termed as a box mat foundation. The condition of the soil. Types of mat foundation.

One reason is if the soil on which the building is constructed does not have a bearing capacity. The type of foundation required depends on many variables. 8 types of the foundation footing are used in. In a raft the entire basement floor slab acts as the foundation.

The load applied from structure to the foundation. Raft foundations also called mat foundations are most often used when basements are to be constructed. Therefore an engineer designing a building with a basement will tend to choose a raft foundation over other types of foundations. 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.

The weight of the building is spread evenly over the entire footprint of the building.
