Excavations – $19.95



This course will teach students about different soil and rock types, as well as soil density and moisture content, all of which affect the potential for a cave-in. Definitions of an excavation and a trench are covered, and the depths at which preventive measures are required are stated. Different types of shoring equipment and trench boxes are discussed and shown graphically, as well as sloping and benching strategies, including slope angles and benching heights and widths.
