It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a waterproof membrane covering for decks and balconies that will be subject to light pedestrian traffic in accordance with the conditions and limitations stated in this evaluation, complies with the following code:
National Building Code of Canada 2015
|ID||Code provision||Solution type|
|09-26-01-02-00-0-00||22.214.171.124.(1) Roofs shall be protected with roofing, i ...||Acceptable|
|09-26-02-00-00-0-00||9.26.2. Roofing Materials||Alternative|
The above opinion(s) is/are based on the evaluation by the CCMC of technical evidence provided by the evaluation holder, and is bound by the stated conditions and limitations. For the benefit of the user, a summary of the technical information that forms the basis of this evaluation has been included.
The product is a polyvinyl chloride membrane with a nominal thickness of 1.5 mm and a heat-set polyester fabric attached to the back. The surface of the product is embossed to provide a textured finish. The membrane is manufactured in rolls that are 1 829 mm wide and 22 m long.
The product is available in a variety of colours.
A typical roof/deck application is shown in the figure below.
This evaluation is valid only for products produced at the following plant:

Conditions and limitations
The CCMC’s compliance opinion is bound by this product being used in accordance with the conditions and limitations set out below.
- The product must be used in conjunction with plywood or concrete substrates. The membrane must be fully adhered to the substrate using the HB Fuller SC-0122 adhesive, and applied as outlined in the installation manual, dated January 2008.
- The product can be considered as an alternative solution to materials referenced in Section 9.26. of Division B of the NBC 2015.
- The product is limited for use in areas that are subject to traffic loads generated by residential occupancies only (light pedestrian traffic).
- The product is limited for use where the roof or deck surface has a minimum slope of 1:48.
- The product must not be exposed to chemical attack or spillage. In situations where extended contact with chemicals or pollutants may occur, the suitability of the product must be determined.
- Any physical or chemical damage to the membrane must be repaired in accordance with the manufacturer’s instructions.
- The product must not be installed with butt seam joints.
- Joints must be shingle-lapped in order to shed water.
- The product must be installed by manufacturer-trained installers and in strict conformance with the current installation manual.
- The product or its packaging must be identified with the following information:
- manufacturer’s name or logo; and
- the phrase “CCMC 13534-R.”
This evaluation is based on demonstrated conformance with the following criteria:
