     IMPERVIUS™, the conference for professionals in Bitumen Waterproofing Membranes highlights on trends and technologies

    EDANA closed the first 2019 IMPERVIUS™ conference with a request from the participants to organise it again.

    The 2019 IMPERVIUS™, the first Bitumen Waterproofing Membranes Conference, organised in Baveno, Italy on 5-6 June, attracted 93 key players from 61 different companies and 24 countries. Presentations focused on raw material development, processes, development in the MENA region, regulation and environmental opportunities.

    There was a general sentiment of deep satisfaction among participants regarding the content of the conference and the networking. The conference opened with a keynote speech on the “Future-Proofing construction in the age of change” given by Frank Hatzack, senior advisor at the Copenhagen Institute for Futures Studies.

    For EDANA and its members in this sector this conference is the natural extension of a 20 years-long history of unique cooperation in non-competitive areas such as sustainability and market prospectives. This is also a unique example of dialogue between proponents of all technologies for the bitumen waterproofing membranes, including but not exclusively nonwovens ones, in line with EDANA’s Outreach policy” said Pierre Wiertz, General Manager of EDANA.
