Code compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a drainage layer against the outside of the foundation wall to protect the wall from transient or intermittent water that may come in contact with the wall surface in accordance with the conditions and limitations stated in this evaluation, complies with the following code:

Ontario Building Code 2017

ID Code provision Solution type
09-14-02-01-02-b- Foundation Wall DrainageAlternative

Ruling No. 96-08-48 (12718-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 2011-09-20 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.

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.

  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.

  • The product is designed to direct water to the footing drainage system when installed against the foundation wall. Install the drainage surface directly against the dampproofing face of the foundation wall (Class B).
  • This drainage product is one part of the total foundation drainage system that consists of a combination of design and construction processes that use different products. For example, a well-functioning footing drain (weeping tile) is required to direct water away from the bottom of the foundation wall.
  • Fasten the product using approved, manufacturer-recommended nails with washers. Place fasteners 100 mm from the sides of the sheet at each corner. Apply adhesive according to the manufacturer’s instructions.
  • The placement and grading of backfill must conform to Subsection 9.12.3., Backfill, of Division B of the OBC 2012.
  • The product has been evaluated for use in depths up to 3.7 m below grade (Type 2).
  • There must be a 6 mm to 13 mm gap between the bottom edge of the insulation and the top surface of the footing to facilitate the emptying of water from the drainage layer to the drain tile.
  • Seal the top surface of the panels with an ultraviolet stabilized polyethylene sheet and an acoustical sealant. This will prevent soil from entering the drainage channels. The polyethylene sheet must be wide enough (minimum 15 mm) to drape over the front and back of the panels.
  • Ensure the top surface of the panels are within 75 mm of the finished grade.
  • The product packaging must be clearly identified with the phrase “CCMC 12718-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:
