Foundations in Expansive Soils

Course Description:

This course presents guidance and information for the geo-technical 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 course 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.

Learning Objectives:

Upon successful completion of this course, participants will be able to:

• Learn causes of foundation heave from changes in soil moisture
• Learn how to recognize the existence of swelling soils on potential sites as early as possible.
• Understand the two major phases of field exploration.
• Learn the problems associated with vertical movement and lateral movement of foundation soil.
