Voltex DS

Voltex-DS is a highly effective waterproofing membrane designed for below-ground applications.
Voltex-DS is a composite of two high-strength geotextiles, 4.88kg of sodium bentonite per square metre, and a LDPE Liner integrally bonded to the non-woven geotextile. The high swelling, low permeability sodium bentonite is encapsulated between the two geotextiles. A patented needlepunching process interlocks the geotextiles together forming an extremely strong composite that ensures uniformity of the bentonite layer, in addition to protecting the product from inclement weather and construction site related damage.


Voltex-DS is designed for below-ground vertical and horizontal structural foundation surfaces. Typical applications include backfilled concrete walls, earthcovered 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. 

Voltex-DS is particularly appropriate for use in conditions where excessive precipitation and / or contamination exist.

Voltex-DS provides Radon protection as defined in BRE Report 212, and is an excellent barrier against Methane and CO2.
