Raft foundations are suitable for medium rise story buildings ranges from four to twelve stories.
Safe 12 mat foundation.
Raft mat foundation is used in those places where we have less bearing capacity of the soil.

It can be considered on higher buildings depending.
These partial safety factors are specified in the design code of your country.
For example the bearing capacity of a raft foundation having a width of 6 m and founded to a depth of 3 m in a sand deposit having relative density corresponding to spt n value of 10 is about 700 kn m 2 which is extremely high.
From framing layout to detail drawing production safe integrates every aspect of the engineering design process in one easy and intuitive environment.
Safe is the ultimate tool for designing concrete floor and foundation systems.
A mat foundation spreads out under the footprint of the building and declines the contact pressure compared to conventional strip or trench footing.
Cohesionless soil in cohesionless soil a mat foundation does not fail in shear.
It is a suitable solution for low bearing capacity soil spread footing cover about 70 of the structure high structure loads soft pockets or cavities of in the soil to unknown extent raft and.

Safe watch and learn video tutorials cover a wide range of topics from basic product overviews to advanced subjects such as post tensioned slab design.
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.
