Compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as dampproofing for below grade concrete walls in accordance with the conditions and limitations stated in this evaluation, complies with the following code:

National Building Code of Canada 2020

ID Code provision Solution type
91302000000009.13.2. DampproofingAlternative

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.

Product information

Product name


Product description

The product is a high-density, low-heat formed, polyethylene sheet roll. The material has a dimpled surface on one side that provides an air gap between the concrete wall and the adjacent soil. The sheet thickness is approximately 0.7 mm. The product is available in rolled sheets form that is 1.22 m to 2.44 m (4 ft. to 8 ft.) wide and 20 m (65.5 ft.) long. When two sheets are joined side by side, they must be overlapped by 200 mm to 300 mm with the dimples meshing.

To ensure correct application, a range of accessories, such as fasteners, anchors, and moulding strips, are included with the product. Photos of the product are in Figure 1 and Figure 2 below.

  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.

  • Based on the evidence provided, the product has been classified as Type 2 (applications up to depths of 3.7 m).
  • The product must be installed in accordance with the manufacturer’s installation manual. In the event of conflict between the manufacturer’s instructions and this evaluation, this evaluation shall govern.
  • The product was evaluated for use against cast-in-place concrete and concrete block foundations only.
  • The product must cover the foundation wall from the top of the footing to the final grade.
  • Cast-in-place concrete and concrete block foundation walls shall have all holes and recesses sealed with mortar. The product must be installed on surfaces that are clean, dry, and free of the following: ice, snow, frost, dust, dirt, oil, grease, cracks, projections and depressions, loose particles, and debris.
  • The product must be used in locations where the foundation wall is well drained, in accordance with Subsection 9.14.2., Foundation Drainage, of Division B of the NBC 2015 and NBC 2020. The product is a dimpled membrane drainage system designed to act as a capillary breaking layer against the foundation wall to protect the wall from transient or intermittent water that may come in contact with the surface of the wall.
  • The product must be protected from exposure to ultraviolet (UV) sunlight within a maximum of 30 days of its installation.
  • The top of the membrane and all vertical joints and terminations must be mechanically fastened with trims, moulding strips, termination bars, or other accessories to prevent soil particles from entering behind the membrane. Accessories used to anchor the product are part of the evaluation.
  • The performance of fixtures used to anchor the product in the wall was evaluated for a single anchor. It is the responsibility of the manufacturer to define the pattern and spacing of anchors, considering the anchor strength as well as the site-specific issues such as the type of soil, how it will interact with the product, as well as the backfilling method used.
  • The product's label and/or packaging must be clearly identified with the manufacturer’s name or logo and “CCMC 14723-R.”
