AQUAZERO slabs are resistant to water and to several atmospheric and chemical agents, but they are not impermeable. Before installing the AQUAZERO slabs, the outer walls must be treated with a waterproof breathable fabric, AQUAZERO BARRIER, to make sure the wall will be impermeable and to protect the insulating materials it contains, as well as the relative metal framework.
The AQUAZERO BARRIER impermeable breathable fabric must be installed horizontally, starting from the bottom, and overlapping the junctions by at least 100 mm, and then fixed with adhesive tape.
