Voltex DS Bentonite Geotextile Waterproofing

Voltex DS is a highly effective waterproofing composite of high strength geotextiles, 1.10 pounds of sodium bentonite per square foot, and a integrally bonded polyethylene liner. The high swelling, low permeable sodium bentonite is encapsulated between the two geotextiles. A proprietary needlepunch 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 DS hydrates and forms a monolithic waterproofing membrane. Voltex DS 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 worldwide.

Voltex DS works by forming a low permeability membrane upon contact with water. When wetted, unconfined bentonite can swell up to 15 times its dry volume. When confined under pressure the swell is controlled, forming a dense, impervious waterproofing membrane. The swelling action of Voltex DS can self-seal small concrete racks caused by ground settlement, concrete shrinkage, or seismic action.

Voltex DS forms a strong mechanical bond to concrete when the geotextile fibers are encapsulated into the surface of cast-in-place concrete.
