Product information

Product name

DMX AG-2™

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.

Manufacturing plant

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

Product name	Manufacturing plant
Product name	Brampton, ON, CA
DMX AG-2™	Product evaluated by the CCMC

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 (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.”

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

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.
