Mechanically stabilized earth or MSE is soil constructed with artificial reinforcing. It can be used for retaining walls, bridge abutments, dams, seawalls, and dikes. Although the basic principles of MSE have been used throughout history, MSE was developed in its current form in the 1960s. The reinforcing elements used can vary but include steel and geosynthetics. MSE is the term usually used in the USA to distinguish it from the name “Reinforced Earth”, a trade name of the Reinforced Earth Company, but elsewhere Reinforced Soil is the generally accepted term.
