Mat Foundation Slab

A mat foundation sometimes called a raft foundation looks like it sounds.

Mat foundation slab.

The construction of mat foundation. A raft foundation also called a mat foundation is essentially a continuous slab resting on the soil that extends over the entire footprint of the building thereby supporting the building and transferring its weight to the ground. When more than one line of columns is supported by a concrete slab it is called a mat foundation. The building then rests on this foundation leading to lesser contact with the land and hence more strength and stability.

Typically reinforced with a double layer of rebar throughout its pad a mat slab is capable of bearing loads at virtually any point and distributing heavy loads across an expanse of weak subsoil. Mat foundation is also known as the raft foundation. It declines the contact pressure in comparison with conventional strip or trench footing. The mat foundation is also reinforced with many bars inside it which run perpendicular to each other.

It is a continuous thick concrete slab on the soil that extends the entire footprint of the building and increases the soil bearing capacity power. This foundation supports the entire building loads and safely transfer it to the ground. Combined footings can be classified generally into four categories. It is used to support storage tanks industrial equipment silos chimneys and various tower structures.

It is a mat of concrete that sits on or just below the ground. A raft or mat foundation is a large continuous rectangular or circular concrete slab that carries the entire load of the superstructure and spreads it over the whole area beneath the building. It is considered as one type of shallow foundation and is useful in controlling the differential settlement. Raft foundation is the essentially continuous slab which is resting on the hard soil which extends over the entire building footprint.

Raft foundation is also known as a mat foundation. Mat slabs are particularly well suited to sites on moderate slopes or where you will be cutting the building pad into a hillside. 1 rectangular combined footing 2 trapezoidal combined footing 3 strap footing mat foundations are generally used with soil that has a low bearing capacity. You may have heard it referred to as a slab foundation a common choice for steel buildings.

Mat foundation is constructed as a large slab which works as the base for the building. A mat foundation is a thick reinforced concrete slab supporting arrangements of columns or walls in a row or rows and transmitting the loads to the soil.
