Bel, that sounds very much the same as revetment (which also comes from the French of course):


• noun 1 a retaining wall or facing of masonry, supporting or protecting a rampart, wall, etc. 2 a barricade of earth or sandbags providing protection from blast or to prevent aircraft from overrunning when landing.

— ORIGIN French revêtement, from Latin revestire ‘reclothe’.

I guess there are subtleties here!
