Volclay Voltex® and Volclay Voltex® DS
Bentonite Geotextile Waterproofing
|
The World's Leading Bentonite-Geotextile Waterproofing System
Voltex is a highly effective waterproofing composite comprised of two high strength geotextiles and 5.2 kg of sodium bentonite per square metre; the most bentonite in any commercially available waterproofing product. The two geotextiles are interlocked by a proprietary needlepunching process which encapsulates and holds the granular bentonite in place and assures a consistent material application. The needlepunching knitted membrane also prevents exposed Voltex from over-hydrating on site.
Voltex is ideal for waterproofing under slabs and property line applications. Under slabs, Voltex can be installed directly over a properly prepared substrate without the need of a concrete mud slab. Its durable composite construction resists damage from tradesman installing reinforcing steel over it and inclement weather.For property line applications, Voltex is simply installed directly to the retention wall and then the concrete is poured directly against it using a single sided form. Other applications include backfilled concrete foundation walls and cut-and-cover tunnels.
Installation of Voltex is fast and easy. Simply place into position and secure with washer head mechanical fasteners. Voltex can be installed to green concrete without primers or adhesives, in virtually any weather, including freezing temperatures and damp conditions. When concrete is poured against Voltex, a tenacious mechanical bond yielding an average adhesion value of 15 pounds per linear inch (15 pli) is created by the wet concrete solidifying around the geotextile fibres.
Voltex is certified by NSF International to conform with the requirements of NSF Standard 61 – Drinking Water System Components – Health effects. Voltex is certified as an external protective barrier material for potable water concrete tanks with a 3,780L capacity or greater.
For contaminated water or salt-water conditions, Voltex is available with a contaminant resistant Volclay sodium bentonite – Voltex CR.
With the durability of the needlepunched composite and the ability to self-heal, Voltex offers major construction advantages over adhered sheet membrane and fluid applied waterproofing.

VOLCLAY VOLTEX® DS
Bentonite-Geotextile waterproofing with Integrated Polyethylene Liner.
Combines the proven waterproofing capabilities of Voltex with a high-strength HDPE Liner. The fibres of the non-woven fabric are bonded to the HDPE liner using a procedure that locks the composite together. Voltex DS is designed for projects that require additional chemical resistance, extremely low water vapour and gas permeability.
For contaminated water or salt water conditions, Volclay Voltex® DS is available with a contaminant resistant Volclay sodium bentonite - Volclay Voltex® DS SWR
