Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a material for dampproofing 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
09-13-02-00-00-0-009.13.2. DampproofingAlternative

Ontario Building Code

Ruling No. 09-38-236 (12658-R) authorizing the use of this product in Ontario, subject to the terms and conditions contained in the Ruling, was made by the Minister of Municipal Affairs and Housing on 2009-12-30 pursuant to s.29 of the Building Code Act, 1992 (see Ruling for terms and conditions). This Ruling is subject to periodic revisions and updates.

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.

  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.”

Administrative information


This evaluation is issued by the Canadian Construction Materials Centre (CCMC), a part of the Construction Research Centre at the National Research Council of Canada (NRC). The evaluation must be read in the context of the entire CCMC Registry of Product Assessments and the legislated applicable building code in effect.

The CCMC was established in 1988 on behalf of the applicable regulator (i.e., the provinces and territories) to ensure—through assessment—conformity of alternative and acceptable solutions to regional building codes as determined by the local authority having jurisdiction (AHJ) as part of the issuance of a building permit.

It is the responsibility of the local AHJs, design professionals, and specifiers to confirm that the evaluation is current and has not been withdrawn or superseded by a later issue. Please refer to the website or contact:
