What Is Mat Foundation | Mat Slab Foundation | Advantage and Disadvantage of Mat Slab Foundation | Types of Mat Foundation | Where Mat Foundation Is Used
Mat slab, sometimes referred to as matt slab, is a part of the shallow foundation.
Mat slab is a hard surface on which all the column or beam are constructed.
Where they have heavily loaded columns or building the mat slab is used.
Mat slab is a common base for many columns.
To ensure a relatively uniform load transfer in high rise building mat slab foundation is used.
Near the ground surface, mat slabs are used.
Mat slab reduced the stress of the soil on the particular zone under the slab to do distribute equally the load that's coming from the superstructure.
To construct a mat slab at first, the ground should be excavated at a uniform flat level.
After that, a waterproof sheet is laid over the excavated ground then a thin layer of plane cement concrete is poured to obtain a perfectly flat surface for the mat slab.
The term matt foundation or mat building expressed that has a type of building in which has a layout, daylighting, and ventilation solved for a plan that’s repeated when needed.
When the soil conditions under the foundation have not adequate strength to bear the load of the superstructure then the matt footing or mat footing is provided.
It provides a perfect grip on the structure of the soil and prevents the tendency of overturning the building.
It is provided when a large number of the floor are exited.
The mat footing prevents the sudden settlement of the structure.
There are two types of mat footing - one is to a square shape and another is a rectangular shape.
The square mat footing is constructed to provide stability to the building.
When a column is too close to the building or structure where mat footing is required.
When two columns are so close to each other or they overlap each other where mat footing is necessary to provide.
The mat footing is constructed where there the strip footing or spread footing is not enough to bear the load that's coming from the superstructure.
To distribute a uniform load from the superstructure to the subsoil mat footing is constructed.
It has good resistance for this the building can not slide during the flood.
The mat slab foundation can help transfer the load of the building to a verse area.
To make an economical structure like when the cost of depth foundation is more than from the shallow foundation then we constructed a mat slab foundation.
In this mat slab foundation, we can reduce the materials cost because when we construct the foundation at the same time the ground floor slab is poured for this reason the time and materials both are safe.
The mat slab is a shallow foundation for this the depth of the foundation is less so the excavation for the foundation is less.
The mat slab foundation can take more than load from the other type of foundation.
In another advantage is that the mat slab foundation can construct in poor soil.
