Cetco Voltex DS-CR Membrane – 1.1m x 5m
High-performance bentonite-geotextile waterproofing membrane with polyethylene liner, ideal for contaminated groundwater and demanding below-ground applications.
Cetco Voltex® DS-CR Membrane is an advanced bentonite-geotextile waterproofing system designed for maximum durability and contaminant resistance in demanding below-ground applications. Measuring 1.1 x 5m per roll, this high-strength composite integrates two geotextiles, 5.0 kg/m² contaminant-resistant sodium bentonite, and an integrally bonded polyethylene liner.
Manufactured using a proprietary needlepunch process, the geotextiles are interlocked to secure even bentonite coverage, protect against damage, and maintain performance in adverse site conditions. Upon backfilling, the membrane hydrates to form a dense, monolithic waterproof barrier that self-seals small cracks caused by settlement, shrinkage, or seismic movement.
Key Advantages:
- Superior Contaminant Resistance: Withstands nitrates, phosphates, chlorides, sulfates, lime, and organic solvents
- Monolithic Waterproof Barrier: Bentonite swells up to 15x its dry volume to block water ingress
- Strong Mechanical Bond: Geotextile fibres encapsulate into cast-in-place concrete for secure adhesion
- All-Weather Installation: Zero VOC, installs to green concrete in wet, cold, or damp conditions
- Proven Worldwide: Suitable for new builds and remedial waterproofing under continuous or intermittent hydrostatic pressure
Applications:
- Backfilled concrete walls & structural slabs
- Earth-covered roofs & tunnels
- Property line construction (soldier pile & lagging, sheet piling, secant/contiguous piling, shotcrete, stabilised earth walls)
- Locations with contaminated groundwater (subject to CETCO Water Compatibility Testing)
