Acotec-walls are non-load bearing partition walls either non-reinforced or with safety wiring, made of hollow-core tongue and groove panels of normal or light-weight aggregate concrete. Acotec-walls are quick to install and no highly skilled labor is needed: they can be built six times faster than traditional brick walls and twice as fast as block work. Excellent as partition walls in all kinds of buildings, Acotec-walls are light, economical, safe, moisture resistant, sound and fire proof as well as fully recyclable. In addition, the wall hollows work as natural conduits for electrical wires and other piping - another place to save in costs and manpower.
