    Active waterproofing of foundations, slabs and underground structures


    SELF-SEALING HYDROPHILIC BENTONITE WATERPROOFING MEMBRANE. Version with PE membrane: double waterproofing for work with high hydraulic head pressure.

     BBA  Direct-contact-with-the-ground  H2o

    VOLTEX® DS is a highly effective waterproofing composite of high strength geotextiles and 5 kg/m2 of sodium bentonite with integrated polyethylene liner. The high swelling, low permeable sodium bentonite is encapsulated between a non-woven and woven geotextile. A proprietary needlepunch process interlocks the geotextiles together forming an extremely strong composite that maintains the equal coverage of bentonite and protects it from extreme weather conditions and construction related damage. Once backfilled, VOLTEX® DS hydrates and forms a monolithic waterproofing membrane. VOLTEX® DS contains zero VOCs, can be installed in almost any weather condition to green concrete, and most importantly, has proven effective on both new and remedial waterproofing projects.
