Professional Engineer Eddie Templeton of the firm of Burns Cooley & Dennis spoke to the Rotary Club of North Jackson at its March 14, 2017 meeting. The subject of his presentation was Expansive Clays, in particular Yazoo Clay. He discussed how Yazoo Clay is present in most of Mississippi , it is particularly expansive by up to 135% when is gets wet, that it expands with a force of up to 16,000 pounds per square foot (PSF). He also discussed how to accommodate its presence in designing structures and their landscaping, by providing a buffer zone between the clay and the bottom of a foundation, by directing water away from a foundation and by planting trees so that they do not dessicate the soil near the foundation. Mr. Templeton is shown during his presentation in the accompanying photo. We thank him for his very interesting and informative presentation.
