The Voltex membrane, an award-winning combination of the superior properties of bentonite coupled with the flexibility of polypropylene geotextiles, is rugged in construction and highly resistant to site damage. Voltex is unique in offering ‘automatic’ mechanical bonding to concrete, the elimination of water tracking, all-weather installation, and application to all types of rough and uneven property line surfaces, including diaphragm walls, contiguous and secant piling and steel sheet piling. Owing to its ease and speed of installation, Voltex offers significant savings when compared to traditional waterproofing systems.
