What Does Revetment Mean?
A revetment is a surfacing material placed on top of soft earth that is subject to flowing water to prevent erosion or to contain hazardous material spills around storage tanks or process vessels. A revetment is typically made of very hard materials for their superior wear resistance.
Corrosionpedia Explains Revetment
Revetments are commonly found on waterfronts to prevent soil erosion or reduce chemical runoff, thus protecting the water's ecosystem. Revetments are also used in channels that provide drainage. In cities prone to flooding, revetments can often be found in channels so that the floodwater does not erode them and render them useless.
In industrial production, revetments are commonly used to contain material spills from equipment such as vessels and storage tanks. The revetments might be constructed from special materials to resist hazardous or corrosive substances.
