Code compliance opinion

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

Code provision Solution type Roofs shall be protected with roofing, i ...Acceptable
9.26.2. Roofing MaterialsAlternative

The above opinion is 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.

  Product information

Product name

DekSmart™ Ultra

Product description

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.

Manufacturing plants

This evaluation is valid only for products produced at the following plants:

  • Winchester, Virginia, United States

  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.”

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:

The NRC has evaluated the material, product, system or service described herein only for those characteristics stated herein. The information and opinions in this evaluation are directed to those who have the appropriate degree of experience to use and apply its contents (i.e., AHJs, design professionals and specifiers). 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. The NRC accepts no responsibility whatsoever arising in any way from any and all use and reliance on the information contained in this evaluation with respect to its compliance to the referenced code(s) and standard(s). The NRC is not undertaking to render professional or other services on behalf of any person or entity nor to perform any duty owed by any person or entity to another person or entity.
