UFC 3-220-07 Foundations in Expansive Soils, Replaced by UFC 3-220-01

This manual presents guidance and information for the geotechnical investigation necessary for the selection and design of foundations for heavy and light military-type buildings constructed in expansive clay soil areas. The information in this manual is generally applicable to many types of structures such as residences, warehouses, and multistory buildings. Emphasis is given to the maintenance of an environment that encourages constant moisture conditions in the
foundation soils during and following construction. Special attention must always be given to specific requirements of the structure such as limitations on allowable differential movement.
