We have many methods to stabilize foundations against the effects of expansive soils. The process of existing foundation repair usually includes foundation stabilization. There are various methods to improve foundation supporting system they are modification of foundation support system itself, under pinning with deeper support, the construction of peripheral barriers that function to isolate soils under the structure or the installation of some sort of system that controls moisture content of soils or the molecular action of the clay when the moisture content is changed. This course material is based on Foundation Performance Association FPA-RC-01-0: Post foundation repair performance of Residential and other Low-Rise Buildings on expansive soils.

At the conclusion of this course, the learner will have a better understanding about the methods of stabilizing the foundations from the effects of expansive soils as well as the following:

• Knowledge of foundation system failures due to expansive soils
• Understands about various methods of foundation repair system
• Knowledge of various foundation maintenance systems
