VOLTEX® Waterproofing Membranes

Leading Waterproofing Worldwide

The VOLTEX® waterproofing membrane line is the proven technology for exceptional waterproofing and contaminant protection with easy installation.

 

It’s the first-choice water barrier across the globe.

Voltex Underslab

World-class waterproofing performance

 

Lighter and more impervious than traditional waterproofing products, VOLTEX combines sodium bentonite layered within a durable geomembrane to provide waterproofing protection for any cast-in-place, below-grade concrete construction, such as:

  • Structural Slabs
  • Property Line Walls
  • Backfilled Walls
  • Cut-and-Cover Tunnels
  • Earth-covered Structures

VOLTEX also outperforms other solutions for precast concrete construction and under contaminated conditions. In both hydrostatic and nonhydrostatic conditions, VOLTEX is dependable, expanding as it absorbs water to seal any small concrete cracks caused by ground settlement or concrete shrinkage, the bentonite core using the water’s own pressure to block gaps.

 

Easy installation saves you money

Featuring exceptional flexibility for maximum conformability when fitting to a structure, VOLTEX can be installed directly to green concrete and placed as soon as forms are removed—no need to wait for the concrete to cure. Requiring no primers or adhesives, simply position VOLTEX and fasten it in place. VOLTEX can be installed even in extreme temperatures, so installation is quick and easy—and easy on your budget.

 

Durable and contaminant resistant

Extremely durable, VOLTEX is self-seaming and self-sealing—there’s no worries about the inevitable small tears and punctures that always occur on construction sites—and is available with a variety of enhancements (see below) to protect against contaminants including saline, nitrates, phosphates, chlorides, sulfates, lime, and organic solvents.

 

Available in four variations

VOLTEX

Standard Bentonite

 

VOLTEX is a proven waterproofing membrane ideal for vertical and horizontal foundation surfaces. VOLTEX incorporates the high-swelling and self-sealing properties of sodium bentonite to form a monolithic, low permeable membrane to protect the structure from water ingress. VOLTEX contains zero VOCs and can be installed on green concrete in almost any weather condition.

VOLTEX DS

Standard Bentonite with HDPE Composite

 

VOLTEX DS combines the proven waterproofing technology of VOLTEX with an integrally bonded polyethylene liner. VOLTEX DS is designed for projects that require additional chemical resistance and low-water vapor permeability.

VOLTEX CR

Chemically Resistant Bentonite

 

VOLTEX CR includes all of the advanced waterproofing capabilities of VOLTEX plus a polymer-treated sodium bentonite for exceptional protection in low to moderate saline or contaminated groundwater conditions, including elevated levels of nitrates, phosphates, chlorides, sulfates, lime, and organic solvents.
