A Mat Foundation is a large, solid concrete base that supports buildings or structures. Think of it like a giant concrete pad that spreads out under the entire building, similar to a thick raft floating on soil. Engineers choose this type of foundation when regular individual footings won't work well, usually for heavy buildings or when the ground conditions aren't ideal. It's particularly common in high-rise buildings, shopping malls, and structures built on soft soil. Other names for this include "raft foundation" or "floating foundation," and you'll often see these terms used interchangeably in job descriptions.
