  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.”
