Dr. Witherspoon has been doing research in soil stabilization techniques for over 20 years and is credited with one patent that provides a method of injecting expansive clay to prevent upheaval. He knows firsthand the damage caused by expansive clays and utilizes several methods that mitigate movement problems caused by these deposits.
Dr. Witherspoon developed an injection method to stabilize the interiors of buildings and houses that mitigates damage to the floor and structure and creates an ion exchange with the clay platelets, resulting in reducing the clay's affinity for water and lowering future swell potential for the stratum injected.
