Technical data sheets: Membranes -Voltex, Voltex DS Other Materials - Bentoseal, Bentogrout, Granules, RX-Waterstop Product manual - Membrane, Waterstop DESCRIPTION Voltex® is a highly effective waterproofing composite of high strength geotextile and 4.88kg 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 worldwide. Voltex 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 Volclay can self-seal small concrete cracks caused by ground settlement, concrete shrinkage, or seismic action; problems over which there is normally no control. Voltex forms a strong mechanical bond to concrete when the geotextile fibres are encapsulated into the surface of poured-in-place concrete. APPLICATION 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. Property line construction applications include secant and contiguous piling, skin wall, metal sheet piling, shotcrete and stabilized earth retention walls. Applications may include structures under continuous or intermittent hydrostatic pressure. Where contaminated ground-water or saltwater conditions exist, use Voltex CR with contaminant resistant sodium bentonite. Voltex CR resists higher levels of the following contaminants: nitrates, phosphates, chlorides, sulfates, lime and organic solvents. ADVANTAGES
