A buried vault for telecommunication equipment is disclosed. It is adapted to connect with telecommunication conduits, especially optical fiber conduits enclosing optical fibers. The vault encloses laser light generating devices for providing signals and also encloses suitable signal switch gear for telecommunication circuitry. The wall is constructed of alternating plies of glass fibers matting and woven roving, each layer being applied and joined with a polymeric resin. It is then covered with a light weight layer, the preferred form being balsa wood and the outside surface is then sprayed with a skin, typically a polyester resin co-mingled with chopped reinforcing fibers of random lengths randomly distributed or glass fibers matting and woven roving plies.
