Excavation is the process of moving earth, rock or other materials with tools, equipment or explosives. It contains a number of important applications including exploration, environmental restoration, mining and construction. Among these, construction is one of the most common applications for excavation. Excavation is used in construction to create building foundations, reservoirs and roads.
Excavation requires unique techniques, tools and machinery to get the job done right. The processes used will depend upon the structure that will result from the construction process.
