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 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||184.108.40.206.(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.
Tower Decking FB
The product is a polyvinyl chloride (PVC) membrane with a non-woven polyester fleece backing. The membrane thickness is 1.5 mm. The surface of the product is embossed to provide a textured finish. The membrane is available in rolls that are 1 829 mm wide and that vary from 23 m to 140 m in length. The product can be cut to required lengths and is available in a variety of colours.
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 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 the following adhesives:
- Bostik Pliobond™ 7008 (on concrete or plywood substrates)
- Tuff Industries Roll-On Latex (on concrete or plywood substrates)
- Tuff Industries Towel-On Latex (on concrete or plywood substrates)
- Tuff Industries Econodek™ (on concrete or plywood substrates)
- 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.
- The product is limited for use where the roof or deck surface has a minimum slope of 1:48.
- 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 qualified applicators only and in strict conformance with the current installation instructions (Rev. 1 - 230419).
- The product or its packaging must be identified with the manufacturer’s name or logo and the phrase "CCMC 13645-R."
This evaluation is based on demonstrated conformance with the following criteria:
