Mat Floating Foundation

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.

Mat floating foundation.

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. 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. 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. A shallow foundation is a type of building foundation that transfers building loads to the earth very near to the surface rather than to a subsurface layer or a range of depths as does a deep foundation shallow foundations include spread footing foundations mat slab foundations slab on grade foundations pad foundations rubble trench foundations and earthbag foundations.

A foundation is laid on ground by excavating some amount of soil. References in periodicals archive. 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. After that a structure is built on it.

One reason is if the soil on which the building is constructed does not have a bearing capacity. 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. Raft mat foundation is used in those places where we have less bearing capacity of the soil.

A floating foundation is the foundation of a building that does not use footings. 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. The foundation actually does float on the earth and moves as temperatures compact and expand the soil.
