Isolated footings are constructed invidually & Mat foundation is making of mat and connecting all footings with this mat
yes
design procedure
They r the same. There is no difference.
The raft will help to avoid any settlement that would occur to strip the foundation. The mat is just placed there to avoid slipping.
You may want to use matte foundation if your face gets oily, greasy or shiny easily.
A foundation drainage mat helps prevent water damage by directing water away from the foundation, reducing the risk of leaks and cracks. This can improve the longevity of the building's foundation by preventing water-related issues that can weaken the structure over time.
The type of mat foundations include flat plate mat, plate thickened under columns, and two-way beam and slab. The other types are plate with pedestal, rigid frame mat, and piled raft.
"The mat (or raft) foundation can be considered a large footing extending over a great area, frequently an entire building. All vertical structural loadings from columns and alls are supported on the common foundation. Typically, the mat is utilized for conditions where a preliminary design indicates that individual columns or footings would be undesirably close together or try to overlap. The mat is frequently utilitzed as a method to reduce or distribute building loads in order to reduce differential settlement between adjacent areas. To function properly, the mat structure will be more rigid and thicker than individual spread footing." A mat foundation is typically used when there are poor and weak soil conditions. (McCarthy, 2007)
A foundation drain mat is a protective layer installed around the foundation of a building to help prevent water damage. It helps by directing water away from the foundation, reducing the risk of water seepage and potential structural damage. The drain mat acts as a barrier, allowing water to drain away from the building instead of pooling around the foundation, thus helping to maintain the integrity of the structure and prevent water-related issues.

A Piling mat is the base or road way which the piling rig will travel on. the design of the piling mat is required to resist the forces from the piling rig during travelling and piling. A piling matt should be constructed of suitable inert material (i.e. not tennis balls).
