VOLTEX® Waterproofing Membrane

Bentonite-Geotextile Waterproofing with Integrated Polyethylene Liner

With more than 50 years of proven performance, VOLTEX waterproofing membranes encapsulates the high-swelling and self-sealing properties of sodium bentonite between two geotextiles. A proprietary needlepunching process interlocks the two geotextiles together. Not only does this form an extremely strong composite that maintains equal coverage of bentonite, but it also protects it from inclement weather and construction-related damage.

    VOLTEX

    Standard Bentonite Geotextile Waterproofing

    Durable Construction

    • Offers major construction advantages over adhered sheet membrane and fluid-applied waterproofing
    • Combines durability of needle-punched composite with the ability to seal-heal
    • Durable composite resists damage from tradesmen installing reinforcing steel over it and inclement weather
    • Ideal for under slab and property line applications
    • Under slab - can be installed directly over a properly prepared substrate without the need of concrete mud slab
    • Property line - install directly to retention wall and pour concrete directly against it using single-sided form
    • Other applications: backfilled concrete foundation walls; cut-and-cover tunnels


    Protection from Water Ingress

    • Can self-seal small cracks while forming watertight laps at the seams
    • Provides a strong mechanical bond to poured concrete
    • Proven effective in structures under continuous or intermittent hydrostatic pressure up to 70m (23 ft)

    Fast and Easy Installation

    • Overlapping seams with mechanical fasteners eliminates installation variables in the field
    • Its durable composite construction eliminates the need for a mud slab

     

    Versatility

    • Can be installed in virtually any weather condition, including freezing temperatures and damp conditions
    • Can be installed on green concrete without primers or adhesives
    • Proven effective in both vertical and horizontal applications—i.e., backfilled and property-line walls

    VOLTEX CR

    Contaminant Resistant Bentonite Geotextile Waterproofing

    Durable Construction

    • High swelling, low permeable, containment resistant sodium bentonite is encapsulated between two geotextiles
    • Durable composite maintains equal coverage of bentonite and remains protected from inclement weather and construction-related damage
    • Ideal for low to moderate saline or contaminated groundwater conditions
    • Resists higher levels of nitrates, phosphates, chlorides, sulfates, lime, and organic solvents
    • Designed for below-grade structural foundation surfaces 
    • Typical cast-in-place concrete applications include: backfilled concrete walls; earth-covered roofs; structural slabs; tunnels; property line construction
    • Property line construction includes: soldier pile and lagging; metal sheet piling; shotcrete; stabilized earth retention walls

    Protection from Water Ingress

    • Can self-seal small cracks while forming watertight laps at the seams

    Accessories

    200x147_AquaDrain

    AQUADRAIN

    AQUADRAIN is a high-flow strip drainage composite designed for collection and transport of water to discharge pipes at the base of a below-grade foundation wall.

     

    Bentoseal

    BENTOSEAL
    A trowel-grade bentonite-based mastic that is used to detail at membrane terminations, around penetrations, over grouted concrete form-tie holes, and provide fillets to inside wall corners. Unlike most mastics, this premium mastic is capable of swelling and self-sealing upon hydration and is VOC compliant. BENTOSEAL can be covered with a waterproofing membrane immediately after application.

     

    200x147_Cetseal
    CETSEAL SEALANT/ADHESIVE
    A multi-purpose, single component polyether moisture cure sealant/adhesive. CETSEAL is a low VOC, 100% solids, non-shrinking product with excellent UV resistance. Available in 10.1 oz cartridges with 12 cartridges per case at 12 lbs (5.4 kg), or 20 oz foil packs with 12 per case at 20 lbs (9 kg).

     

    200x147_Envirosheet

    ENVIROSHEET
    A self-adhering composite sheet waterproofing membrane, ENVIROSHEET consists of 56-mils of rubberized asphalt and a 4-mil cross-laminated, polyethylene carrier film. The two components are laminated together to produce an extremely tough waterproofing barrier.

     

    200x147_HydrobarTubes

    HYDROBAR TUBES
    Consisting of VOLCLAY granular bentonite encapsulated in a water-soluble film tube, HYDROBAR TUBES are a convenient means of providing extra waterproofing protection at the critical wall to footing intersection joint. Each tube is 50 mm (2") dia. x 600 mm (2 ft) long. Available in 16 tubes per box for 9.75 m (32 linear feet).

     

    Swelltite_Seamtape-11-1

    SEAMTAPE
    A single-sided tape consisting of an aggressive rubber-based adhesive with a durable polyethylene backing. Seamtape is primarily used to seal the overlap seams for both backfilled foundation walls and horizontal deck applications. Seamtape protects the overlap seams against debris intrusion during backfill and damage from rain prior to backfilling. Available in 3” (75 mm) x 50-Ft (15.2 m) rolls; 8 rolls per case

    200x147_TB-boot

    TB-BOOT TIE-BACK COVERS
    A single piece, pre-formed thermoplastic cover that provides a simple and quick waterproofing installation detail. The thick thermoplastic construction provides the strength and durability to withstand the concrete placement. Available in three sizes: TB-6SN is 6” (150 mm) deep, TB-8 is 8” (200 mm) deep, and TB-10 is 10” (250 mm) deep.

    200x147_Waterstop-RX

    WATERSTOP-RX

    WATERSTOP-RX is a hydrophilic strip waterstop designed to stop water infiltration through cast-in-place concrete construction joints by expanding upon contact with water to form a positive seal against the concrete.

     

    Organoclay

    WATERSTOPPAGE
    WATERSTOPPAGE is chemically treated, granular sodium bentonite used as a detailing accessory product for CETCO Waterproofing Systems. When wetted, WATERSTOPPAGE forms into a dense, low permeable material that combines with the sodium bentonite in the waterproofing products to form a seamless waterproofing membrane.
