Mat Slab Vs Slab On Grade

Mat foundations are intended to support heavy column loads and are intended to throw the loads lower into the soil profile but at lower stress levels because of the large area.

While a raft mat foundation is a type of concrete slab on grade it is used to support loads like a conventional concrete footing would in that it distributes the load to the soil below only over a much larger area. Slab on grade is supposed to carry its own weight and the live load. The main difference will probably be in the reinforcement.

Slabs which are directly laid on the earth to support walls and other structural elements are called as slab on grade or grade slabs. Mat footing on the other hand is supposed to take the. However architects engineers and construction workers may have a more refined interpretation. In laymen s terms yes.

Think of it like a very big spread footing. For the soil supported mat the soil is assumed to have a linear response which is defined with the subgrade modulus and is characterized by a set of springs which can vary in stiffness at points under the mat. There are two different types supported slab on grade and monolithic slab on grade. The mat or structural slab is modeled with linear finite elements.

Wire mesh is cast into the concrete to reduce chances of cracking. Many people use the terms slab on grade amp. Slab on grade foundation is described as a single layer of concrete poured generally all at once onto a bed of crushed gravel which serves to improve drainage.
