There are several types of mat foundation:
1. Flat Plate Mat Foundation - This is a single layer reinforced concrete slab foundation which is commonly used for low-rise structures such as single-family homes.
2. Flat Slab Mat Foundation - This type of mat foundation is similar to flat plate mat foundation but includes thickened edges to support the walls.
3. Two-Way Beam and Slab Mat Foundation - This type of mat foundation has a grid of reinforced concrete beams that support a two-way reinforced concrete slab.
4. Ribbed Mat Foundation - This type of mat foundation consists of a series of closely spaced ribs that support the slab.
5. Cellular Mat Foundation - This type of mat foundation is made up of interconnected cells that contain soil or granular material to reduce differential settlement.
6. Piled Mat Foundation - This type of mat foundation is supported by a group of piles that are driven through the slab and into the soil.
