Mat slabs are particularly well suited to sites on moderate slopes or where you will be cutting the building pad into a hillside.
What is a mat slab.
You may have heard it referred to as a slab foundation a common choice for steel buildings.
Raft foundation is a thick concrete slab reinforced with steel which covers the entire contact area of the structure like a thick floor.
In other words a shallow foundation.
Raft foundation is mat foundation.
Meaning of mat slab.
The building then rests on this foundation leading to lesser contact with the land and hence more strength and stability.
To support this engineers designed a 4 foot thick reinforced mat slab.
And they are suitable for building on poor soil excluding peat and organics that is uniform in consistency.
Mat foundations are appropriate for light pre engineered metal buildings with multi span rigid frames and flexible walls.
A mat foundation is a thick reinforced concrete slab supporting arrangements of columns or walls in a row or rows and transmitting the loads to the soil.
Typically reinforced with a double layer of rebar throughout its pad a mat slab is capable of bearing loads at virtually any point and distributing heavy loads across an expanse of weak subsoil.
Sometimes area covered by raft may be greater than the contact area depending on the bearing capacity of the soil underneath.
Mat foundation is constructed as a large slab which works as the base for the building.
It is a mat of concrete that sits on or just below the ground.
Because of the complexity of the mat geometry and loadings corn products asked ambitech engineering corporation of downers grove ill to verify the design using pcamats and staad software.
Now what is raft foundation.
It is used to support storage tanks industrial equipment silos chimneys and various tower structures.
What does mat slab mean.
The total dead weight that will rest on this slab will be over 12 million pounds.
Mat slab foundations can be constructed near the ground surface or at the bottom of basements.
It is a continuous thick concrete slab on the soil that extends the entire footprint of the building and increases the soil bearing capacity power.
Mat foundation is also known as the raft foundation.
Mat slab foundations distribute heavy column and wall loads across the entire building area to lower the contact pressure compared to conventional spread footings.
