COLPHENE® 2090AR is a self-adhesive flexible SBS elastomeric bitumen waterproofing membrane with a glass fleece reinforcement.


 COLPHENE® 2090AR on the underside is protected by a silicone release film and the membrane is self-protected by slate chippings on the topside.


  • Flame free and ease of application: COLPHENE® 2090 AR meets the standards of a professional waterproofing system as well as a auto-adhesive application.
  • Reliability and durability: the SBS elastomeric bitumen used in the manufacturing process of the COLPHENE® membranes guarantees a high level of reliability and an excellent resistance to aging therefore a durable protection of the building.
  • Excellent adherence: the COLPHENE® membranes highly grips to most supports: metal, concrete, wood, fibre-cement, zinc, aluminium. The adhesion is reinforced by the use of ELASTOCOL® 600 primer which is essential for porous supports.
  • Anti-root reinforcement on topside to prevent piercing.
  • Very good mechanical resistance: the COLPHENE® membranes offer high resistance to tearing and puncture.


COLPHENE® 2090AR is used as a second layer for roof waterproofing. All the applications are described in the French Standards DTU, Technical Guidelines or Technical Approvals. For more details refer to specific technical information.

COLPHENE® 2090 AR must be applied directly onto treated surfaces:
- Brush and dry surface.
- If needed, cover the surface with a coat of ELASTOCOL 600 or ELASTOCOL 350 primer using a brush or a roller.
- Once dry, put roll into place and set it to the appropriate size.
- Apply primer on the surface.
- Pull on sheet and lay it out while flattening the surface so as to avoid air getting trapped.
- Ideal laying temperature: + 10 °C.
- Edge covering: Before the overlapping procedure the chippings must be covered with a coat of COLPHENE® glue using a spatula. COLPHENE® glue is delivered in the COLPHENE® 2090 AR chuck.
