Mat Foundation Slab

Combined footings can be classified generally into four categories.

Mat foundation slab. 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. The mat foundation is also reinforced with many bars inside it which run perpendicular to each other. Raft foundation is also known as a mat foundation. And they are suitable for building on poor soil excluding peat and organics.

It is a mat of concrete that sits on or just below the ground. A mat foundation sometimes called a raft foundation looks like it sounds. It is considered as one type of shallow foundation and is useful in controlling the differential settlement. 1 rectangular combined footing 2 trapezoidal combined footing 3 strap footing mat foundations are generally used with soil that has a low bearing capacity.

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. The building then rests on this foundation leading to lesser contact with the land and hence more strength and stability. You may have heard it referred to as a slab foundation a common choice for steel buildings. Mat foundation is also known as the raft foundation.

Raft foundation is the essentially continuous slab which is resting on the hard soil which extends over the entire building footprint. It declines the contact pressure in comparison with conventional strip or trench footing. Mat foundation is constructed as a large slab which works as the base for the building. 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. It is used to support storage tanks industrial equipment silos chimneys and various tower structures. Mat foundations are appropriate for light pre engineered metal buildings with multi span rigid frames and flexible walls. The construction of mat foundation.

In other words a shallow foundation. This foundation supports the entire building loads and safely transfer it to the ground.
