Raft Or Mat Foundation Uses

Raft or mat foundation is used when the soil layer is unstable.

Raft or mat foundation uses.

One reason is if the soil on which the building is constructed does not have a bearing capacity. 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. Raft foundation is also known as mat foundation. Mat foundation also known as a raft foundation or floating foundation is a way of giving extra support to a building.

It is used to reduce differential settlement of buildings. For building foundation design it is one of the most important aspects is to choose the right foundation. There are many reasons why mat foundation is chosen by builders across the globe. Definition of raft foundation along with working principle when to choose raft types of raft foundation materials of raft foundation raft construction steps etc are discussed below.

A raft foundation is often used when the soil is weak as it distributes the weight of the building over the entire area of the building and not over smaller zones like individual footings or at individual points like pile foundations this reduces the stress on the soil. The concept of stress is very basic to civil engineering. When to use raft or mat foundation in construction. Mat foundation is also used for low bearing capacity soil in order to spread the load of a building and hence construct a stable foundation.

Here is the list of some of the major aspects when to use or choose a mat foundation. Raft mat foundation is used in those places where we have less bearing capacity of the soil. When the soil has a low bearing capacity.
