  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 can be used as a membrane that is fully adhered to a continuous solid substrate, such as a plywood or concrete deck and balconies that are subject to light pedestrian traffic.
  • The product must be used only in conjunction with plywood or concrete substrates. The membrane must be fully adhered to the substrate with adhesives WD-1000 (on concrete or plywood substrates) or WD-7633 (on plywood substrates only) and applied as per the installation manual.
  • The product is limited for use in areas that are subject to traffic loads generated by residential occupancies only.
  • 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.
  • The product is limited for use where the roof or deck surface has a minimum slope of 1:48.
  • Joints must be shingle-lapped in order to shed water.
  • The product must be installed by approved applicators only and in strict conformance with the manufacturer’s installation instructions.
  • The product or its packaging must be identified with the manufacturer’s name or logo and the phrase “CCMC 13606-R.”

Administrative information


This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:

This evaluation is only valid when the product is installed in strict compliance with the stated conditions and limitations of evaluation and the applicable local building code. In circumstances where no applicable local building permit is issued and that no confirmation of compliance ‘for use in the intended field application’ is undertaken, this evaluation is null and void in all respects. This evaluation is provided without representation, warranty, or guarantee of any kind, expressed, or implied, and the NRC provides no endorsement for any evaluated material, product, system or service described herein.
