Which type of foundation is used for the construction of building on black cotton soil ?

Mat foundation :- Black cotton soil is clay or loose type of soil and is considerably swells and shrinks by variation in moisture content. The variation in the volume of the soil is to the extent of 20 to 30% of the original volume.
