COLPHENE BSW Tanking Membrane

Equus Industries

EQUUS SOPREMA COLPHENE BSW Tanking system is a fully reinforced membrane system designed for underground, below slab horizontal, and vertical external blind side waterproofing applications. With its unique design, it can be used in high density areas near buildings that limit access and excavation.

COLPHENE BSW membranes are high-performance waterproofing membranes composed of reinforced, SBS modified bitumen. The upper surface is coated with crystals that specifically adhere to the concrete slab when freshly poured against the membrane. This adhesion with the concrete creates a watertight bond preventing water infiltration to the concrete.

Key Benefits:

  • Adheres to reinforced concrete floor slab with specifically designed crystal surface and resists soil settlement and dimensional movements
  • Light-weight membrane for wall waterproofing
  • High hydrostatic pressure resistance
  • Does not rely on pressure or curing
  • Quick horizontal installation time
  • Heat welded, watertight laps with DUO SELVEDGE
  • 50 year underground durability
  • 20 year material warranty
  • BRANZ Approved system.
  • Complies with the New Zealand Building Code.
  • Warranties available when used in conjunction with the correct specification and applied by an Equus Certified Applicator.

Scope of use

COLPHENE BSW is designed as a robust tanking solution and to protect areas against a high risk of hydrostatic water pressure but COLPHENE BSW is suitable for a range of underground waterproofing situations. Solutions can be provides for buildings of all sizes and requirements including pre-applied loose laid under-slab, pre-applied to vertical walls, or post applied to vertical walls with options for torch-on or self-adhesion.

Superior Adhesion

COLPHENE BSW adheres to cast-in-place concrete, benefiting from the heat of the exothermic reaction that occurs during the curing process of the concrete. The superior adhesion is caused by the chemical and mechanical bond between the waterproofing membrane and structural concrete, which not only prevents water infiltration inside the building but also prevents lateral water migration between the membrane and concrete.

Safer Installation

The COLPHENE BSW H and COLPHENE BSW V membranes have a unique installation advantage. They are finished with SOPREMA’s DUO SELVEDGE lap technology. The first section of the of the DUO SELVEDGE lap is self-adhesive, which is pressed closed initially. This protects components under the membrane from the flame of a gas torch. The remaining section of the lap area can then be safely torched. This allows for a fully heat welded lap while protecting the underneath materials such as thermal insulation.

NZBC H1 Energy Efficiency

Complete underground solutions are available that include thermal insulation. Adding insulation within the underground waterproofing system meets the required R-values to comply with the recent changes to NZBC H1 Energy Efficiency requirements, and allows more design flexibility for other areas of the project.
