"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.

What is difference between combined footing and raft foundation?

A Combined footing is a long footing supporting two or more columns in one row. While a Mat or Raft foundation is a large footing, usually supporting several columns in two or more rows.


Difference between deep and shallow foundation?

Shallow foundation: A type of foundation that is used when the earth directly beneath a structure has sufficient bearing capacity to sustain the loads from the structure Deep foundation: A type of foundation that is used when the soil near the ground surface is weak. 1. Light, flexible structure: older residential construction, residential construction which include a basement, and in many commercial structures, 2. Nice soil condition: hard, uniform soil. 3. Cheaper than deep foundation 4. Easier construction 5. Typically types: spreading footing foundation, slab-on-grade foundation, pad foundation, strip foundation, and raft foundation. Spreading footing foundation: controlled by several factors: lateral and vertical capacity, penetration through near surface layers likely to change volume due to frost heave or shrink-swell. Mat-slab foundation: the distribution of loads in a mat slab helps reduce differential settlement due to the non-uniform building loads 1. Heavy, rigid structure: other uncommon building, such as large bridge, tower, and the Empire State Building. 2. Poor soil condition: liquefaction, soft clay and sands. 3. Typically more expansive 4. More complex to construct and more time than shallow foundation. 5. Typically types: battered piles, bearing piles, caissons, and friction piles. Friction piles: Friction piles obtain a greater part of their carrying capacity by skin friction or adhesion. This tends to occur when piles do not reach an impenetrable stratum but are driven for some distance into a penetrable soil. Their carrying capacity is derived partly from end bearing and partly from skin friction between the embedded surface of the soil and the surrounding soil. End bearing piles: End bearing piles are those which terminate in hard, relatively impenetrable material such as rock or very dense sand and gravel. They derive most of their carrying capacity from the resistance of the stratum at the toe of the pile.

Difference between raft and mat foundation?

The raft will help to avoid any settlement that would occur to strip the foundation. The mat is just placed there to avoid slipping.

What are the benefits of using a foundation drainage mat for preventing water damage and improving the longevity of a building's foundation?

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.


What are the types of mat foundation?

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.


What is the purpose of a foundation drain mat and how does it help in preventing water damage to buildings?

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.
