Revetted

Revetted is a term used as an adjective or past participle to describe a surface that has been covered or faced with a protective lining, known as a revetment. A revetment is a structural facing applied to a slope, bank, wall, or other vertical or inclined surface to resist erosion, retain soil, or add stability. The word derives from revêtir, French for to clothe or cover.

In civil engineering and construction, revetted surfaces are common on sea and river defenses, embankments, and retaining walls. Stone, masonry, concrete panels, or timber lagging may be laid against the face to absorb energy, prevent rockfalls, and reduce moisture intrusion. In hillside stabilization, revetments help protect slopes from weathering and landslides and are often used alongside drainage and soil nails. In rail and road works, revetments are used to protect cuttings and prevent slope movement.

In military architecture, revetted walls or parapets provide protection for defenders by enclosing or reinforcing exposed surfaces. Trench constructions sometimes employ a revetted side to shield occupants from enemy fire and collapse.

Materials and forms vary: rock or stone revetments, concrete facing (precast panels or poured), and timber or gabion revetments. The adjective revetted can describe any surface that has undergone this facing process, such as a revetted hillside or a revetted wall.
