What Is A Berm?

A berm is a raised bank or terrace used in containment or spillways. A berm is used in the containment of environmental hazards such as oil or industrial water waste. Construction of a berm is usually of earth or artificially manufactured materials and is often intended as a safety feature to confine hazards or to prevent soil erosion. The term “berm” may apply to numerous applications but generally applies to any or all raised or ridged embankments intended to prevent spill over. Sometimes, a berm may be used in terracing applications, but is generally used for spillways and hazard prevention in environmentally sensitive situations.
