Cetco Voltex DS Bentonite Geotextile Membrane with Polyethylene – 1.1m x 5m

Bentonite geotextile waterproofing membrane with integrated polyethylene liner. VOLTEX DS® is a highly effective waterproofing composite of high strength geotextiles,4.8 kg/sqm of sodium bentonite per square metre, and a integrally bonded polyethylene liner. The high swelling, low permeable sodium bentonite is encapsulated between the two geotextiles. A proprietary 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 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 fibres are encapsulated into the surface of cast-in-place concrete.

Applications: 

VOLTEX DS® is designed for below-ground structural foundation surfaces. Typical cast-in-place concrete applications include backfilled concrete walls, earth-covered roofs, structural slabs, tunnels, and property line construction. Property line construction applications include soldier pile and lagging, steel sheet piling, secant/contiguous piling, shotcrete and stabilized earth retention walls. Applications may include structures under continuous or intermittent hydrostatic pressure.

Limitations: 

VOLTEX DS® should only be installed after substrate preparation has been properly completed and is suitable to receive the waterproofing system. Concrete work should be cast-in-place with conventional forms that produce a smooth surface.

VOLTEX DS® is designed for below-ground waterproofing applications where the product is properly confined. VOLTEX DS® should not be installed in standing water or over ice. If ground water contains strong acids, alkalis, or is of a conductivity of 2500 ?mhos/cm or greater, water samples should be submitted to the manufacturer for compatibility testing. ULTRASEAL XP may be required if contaminated ground water or saltwater conditions exist.

VOLTEX DS® is designed for use under reinforced concrete slabs 100 mm thick or greater on a compacted earth/gravel substrate. VOLTEX DS® requires a minimum 150 mm thick reinforced concrete slab if installed over a concrete blinding. VOLTEX DS® is not designed for split-slab plaza deck construction.

VOLTEX DS® is not intended to seal expansion joints; contact CETCO for expansion joint applications. Do not use VOLTEX DS® on masonry block foundation walls. Consult CETCO for special installation guidelines that apply to shotcrete and precast concrete construction.

Size and Packaging: 

VOLTEX DS® is available in 1.1 m x 5 m rolls. Typical roll weight is approximately 37 kg. VOLTEX DS® is packaged 35 rolls per pallet (176 sqm).
