Product information

Product name

Dörken DELTA^®-MS dampproofing membrane

Product description

The product is a high-density, polyethylene, quasi-rigid plastic sheet membrane that is brown in colour and extruded in such a way to produce a dimpled surface on one side (dimples are 8-mm high) and a smooth surface on the other. The product is available in rolls 20 m (65 ft. 7 in.) long and 1.07 m (3 ft. 6 in.) to 3 m (9 ft. 10 in.) wide.

A range of accessories, fasteners, sealants and mould strips is available to assist in the correct application of the product.

Product profiles and anchors are illustrated below in Figure 1, Figure 2 and Figure 3.

Manufacturing plant

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

Product name	Manufacturing plant
Product name	Beamsville, ON, CA
Dörken DELTA^®-MS dampproofing membrane	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 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 Report, this Report shall 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.
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 drainage 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 30 days 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 Report does not exempt the project from requiring proper engineering design of the drainage system.
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 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 with trim, 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 product’s label and/or packaging must be clearly identified with the following:
- manufacturer’s name or logo; and
- the phrase “CCMC 12658-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.
