Voltex is a highly effective waterproofing composite of high strength geotextile and 4.88 kg of sodium bentonite per square metre. The high swelling, low permeable sodium bentonite is encapsulated between a non-woven and woven geotextile.

A patented needle-punch process interlocks the geotextiles together forming an extremely strong composite that maintains the equal coverage of bentonite, as well as, protects it from inclement weather and construction related damage. Once backfilled, Voltex hydrates and forms a monolithic waterproofing membrane. Voltex contains zero VOC, can be installed in almost any weather condition to green concrete, and most importantly, has proven effective on both new and remedial waterproofing projects.


Voltex is designed for below-ground vertical and horizontal structural foundation surfaces. Typical applications include backfilled concrete walls, earth covered roofs, structural slabs, tunnels and property line construction.
