Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a foundation wall drainage material in accordance with the conditions and limitations stated in this evaluation, complies with the following code:

Ontario Building Code 2017

Code provision Solution type
9.14.2.1.(2)(b) Foundation Wall DrainageAcceptable

The above opinion is 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:

DMX AG

Product description

The product is a high-density polyethylene (HDPE), semi-rigid, thermally formed sheet that is smooth on one side and dimpled on the other side to provide an air gap between the membrane and the wall surface. The sheet thickness is 0.6 mm. The product is available in rolled sheets 3.05 m (10 ft.) wide. When two sheets are joined side by side, they must be overlapped by 200 mm to 300 mm with the dimples meshing. When two sheets are joined top to bottom, they must be overlapped by 150 mm.

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 below.

Manufacturing plant

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

  • Brampton, Ontario, Canada

  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, Class B.
  • The product must be installed in accordance with the manufacturer’s instructions.
  • The product was evaluated for use against cast-in-place and concrete block foundations only.
  • The product is a dimpled membrane designed to act as a protective or capillary breaking layer against a foundation wall to protect it from transient or intermittent water that may come in contact with the surface of the wall.
  • The product has been evaluated for use in vertical applications in depths of 3.7 m below grade. Applications greater than 3.7 m are considered to be outside the scope of this evaluation.
  • The product is only one portion of the total foundation drainage system, which consists of a combination of design and construction processes that use different products. In particular, the product must be bent at the footing that is at the bottom of the wall to guide water past the cold joint to a drainage pipe located beyond the footing. This pipe will drain the water collected by the product toward an outflow (i.e., sewer). The product relies on a foundation wall drainage system that conforms to Subsection 9.14.3., Drainage Tile and Pipe, or to Subsection 9.14.4., Granular Drainage Layer, of Division B of the OBC 2017.
  • The placement and grading of backfill must conform to the requirements of Subsection 9.12.3., Backfill, of Division B of the OBC 2017. It is recommended that an impervious “topping off” layer of clay or silt material be placed on top of the backfill to create a positive slope that would lead surface water away from the building.
  • The product must be protected from exposure to ultraviolet (UV) radiation from the sun within a maximum of 30 days of its installation.
  • The long-term performance of a drainage system will depend 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. There should be a proper engineering design for the drainage system.
  • Pattern and spacing of anchors must be designed to consider the site-specific issues such as the type of soil and how it will react to the product, as well as the backfilling methods 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.
  • The product must be labelled with the manufacturer’s name or logo and the phrase “CCMC 13182-R.”

Administrative information

Disclaimer

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:
