The WIDOPAN AVS-mat is a composite decoupling, drainage and sealing element used on balconies, terraces, walkways as well as on parking levels and traffic areas. The AVS-mat is used directly as a processable toping for liquid waterproofing on fresh concrete (walkable), resp. on existing damp concrete as well as on old tiles or ceramic surfaces or any other floor systems.
Through its integrated channels between the fleece lamination on the front and the back, the AVS mat diverts arising vapour pressure. This assures that the abuilding gets dry which saves energy. Furthermore, this prevents any formation of bubbles. The drainage of evaporating moisture is ensured by the open wall connection. Z-profiles then form the rainproof upward closure.
