Mat Floating Foundation

Raft mat foundation is used in those places where we have less bearing capacity of the soil.

Mat floating foundation.

A raft or mat foundation consists of a large concrete slab or a slab and beam system resting on soil or rock and supporting all the loads through a number of columns or walls. Raft or mat foundations 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. The reinforcing system in the mat can be quite substantial with heavy reinforcing bar mats in the bottom top or both locations within the mat depth. At those places we use mat foundations to distributes the whole loads of the structure to the soil when the area of the footing was increase than the soil load bearing capacity will also increase because this foundation reduces the stress on the soil at the same place.

Depending on the total load applied to the mat and underlying foundation system the thickness of mat foundations can vary from 1 ft 0 3 m to more than 20 ft 7 m. After that a structure is built on it. A floating foundation is the foundation of a building that does not use footings. The foundation actually does float on the earth and moves as temperatures compact and expand the soil.

In case of floating foundation the weight of structure built on the soil is nearly equal to the total weight of the soil including water in. It is a poured cement slab that has two deep edges that go just below the frost line in northern climates.

A floating foundation is a type of foundation constructed by excavating the soil in such a way that the weight of structure built on the soil is nearly equal to the total weight of the soil excavated from the ground including the weight water in the soil before the construction of structure. Comprising a deck box 3 4 chord square truss structure mono column and a mat foundation the mcp is able to operate in oil fields with soft seabeds that pose challenges for conventional jack up rigs. Mat foundation also known as a raft foundation or floating foundation is a way of giving extra support to a building there are many reasons why mat foundation is chosen by builders across the globe.
