Technical Details

COLPHENE BSW V 3.0 is designed for various applications in substructure waterproofing:

  • Blind side waterproofing assemblies
  • Pre-applied below grade waterproofing systems
  • Protection against hydrostatic pressure
  • Resistance to lateral water migration
  • Applications requiring robust chemical resistance

Product FAQ

COLPHENE BSW V 3.0 is suitable for blind side waterproofing assemblies, pre-applied below grade waterproofing systems, protection against hydrostatic pressure, resistance to lateral water migration, and applications requiring robust chemical resistance.

COLPHENE BSW V 3.0 is installed by ensuring surface preparation for a clean, dry substrate. The membrane is rolled out and positioned, aligning the side-laps for heat-welding. Using a propane torch or hot air gun, the DUO SELVEDGE technology allows for secure bonding to the structural concrete, ensuring a watertight seal. Proper handling and safety measures should always be followed during installation.

Using COLPHENE BSW V 3.0 offers several key benefits: it provides exceptional bond strength to poured concrete, ensuring reliable waterproofing; its DUO SELVEDGE technology enhances installation safety and efficiency; it resists aggressive chemicals, radon, and methane, making it suitable for challenging environments; the membrane is robust against both static and kinetic forces with crack bridging ability; it maintains watertight integrity under high hydrostatic pressures and lateral water migration; and it is durable under UV exposure and high temperatures, ensuring long-lasting performance in substructure construction.

COLPHENE BSW V 3.0 meets standards including ASTM D5147, ASTM E154, ASTM D903, ASTM D570, ASTM E96, ISO/TS 11665-13, and ISO 15105-1, ensuring high performance and reliability in waterproofing applications.

The warranty for COLPHENE BSW V 3.0 varies by project. Please contact SMCC for specific details.

COLPHENE BSW V 3.0 features several key technical properties: it has a thickness of 3.0 mm and a tensile strength of 15/10 kN/m (MD/CMD). The product offers an elongation at break of 45%/60% and a tear strength of 600 N/400 N (MD/CMD). It exhibits low water absorption (<0.5%) after 24 hours and provides resistance to hydrostatic pressure greater than 110 m. Additionally, it demonstrates excellent adhesion to poured structural concrete (3400 N/m) and maintains flexibility at low temperatures, unaffected down to -30 °C. The surface includes specially engineered silicon dioxide crystals for enhanced performance.
