Notes:
(1) Used for waterproofing tunnels, cellars and foundations.
(2) All materials cause high levels of environmental damage. The use should therefore generally be reduced, and water penetration should be hindered using
other methods such as placing the bathroom on the ground floor and avoiding balconies on roofs of houses.
