Product information

Product name

RESISTO Drainage Board

Product description

The product is a high-density 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 product’s sheet pattern features 6.11-mm-high double-cone dimples, which are spaced at approximately 30 mm on centre (o.c.), joined by channels (see Figure 1), and features two different attachment types (see Figure 2 and Figure 3). The product is available in rolls of 15.2 m and 20 m long, 0.86 mm thick, and up to 2.44 m wide.

Product evaluated by the CCMC Indicates that the product from this manufacturing facility has been evaluated by the CCMC

  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 for use in vertical applications in depths up to 3.7 m below grade. Application depths greater than 3.7 m are considered to be outside the scope of this evaluation.
  • The product must be installed in accordance with the manufacturer’s instructions. In the event of conflict between the manufacturer’s instructions and this evaluation, this evaluation will govern.
  • The product was evaluated for use against cast-in-place and concrete block foundations only and must cover the foundation wall from the top of the footing to the final grade.
  • Unit masonry walls and concrete walls must have all holes and recesses sealed with mortar. The product must be installed on surfaces that are clean and dry, and free of 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.
  • The product is a dimpled membrane dampproofing system designed to act as a protective layer or a capillary breaking layer against the foundation wall, to protect the wall against transient or intermittent water that may come in contact with the wall’s surface.
  • The product must be protected from exposure to ultraviolet (UV) light (sunlight) within a maximum of six months of installation.
  • Long-term performance of the dampproofing system depends on local conditions, such as the soil type, hydrogeology of the site, mineralogy and presence of microorganisms in the soil (i.e., iron ochre), as well as compatibility of the filter with the soil, among other issues. Compliance with this evaluation does not exempt the project from requiring proper engineering design of the drainage system.
  • The performance of fixtures used to anchor the product to the wall was evaluated for a single anchor. It is the responsibility of the manufacturer to define the pattern and spacing of anchors, taking into consideration the anchor strength as well as site-specific issues, such as the type of soil, how it will interact with the product, as well as the backfilling method used.
  • The top of the membrane and all vertical joints and terminations must be mechanically fastened and sealed to prevent soil particles from entering behind the membrane. Accessories used to anchor the product are part of the evaluation.
  • The product’s label and/or packaging must be clearly identified with the following:
    • the manufacturer’s name or logo; and
    • the phrase "CCMC 14472-R."

Code compliance as an acceptable solution

Code Compliance via Acceptable Solutions

If a building design (e.g. material, component, assembly or system) can be shown to meet all provisions of the applicable acceptable solutions in Division B (e.g. it complies with the applicable provisions of a referenced standard), it is deemed to have satisfied the objectives and functional statements linked to those provisions and thus to have complied with that part of the Code.

National Building Code of Canada, Sentence A-1.2.1.1.(1)(a)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Acceptable Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

  • complying with the applicable acceptable solutions in Division B, or
  • using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.

Code compliance as an alternative solution

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions
