Since 1966 IMPER ITALIA produces bitumen-polymer waterproofing membranes (MBDP), and is “leader” both for the quality of production and for its presence on the national and international markets. This is also confirmed by certificates of technical suitability, issued by the ITC (CNR) and by the member institutes of the UEAtc (Union Européenne pour l’Agrément technique dans la construction) such as: CSTB (France), BBA (Great Britain), IAB ( Ireland), UEAtc (Belgium), as well as other certificates of international organizations such as EMI (Hungary), JIS (Japan), BRANZ (New Zealand), Factory Mutual System (USA), Bureau Veritas (France), SOCOTEC (France), Laboratoire Central Ponts et Chaussées (France).
