for the Applicant


  1. The Applicant

Van Akker Homes (London) Ltd. is the holder of a permit under the Building Code Act, 1992 to construct a single family dwelling (i.e. house) at 495 Palmtree Avenue, London, Ontario.

  1. Description of Constrution

The applicant has constructed a single family dwelling (i.e. house) with a basement foundation. HITEK 20 Cordrain material is used as a drainage layer on below grade foundation walls.

  1. Dispute

The dispute between the Applicant and Respondent concerns sufficiency of compliance with Clause of the Building Code. At issue is the use of HITEK 20 Cordrain as a drainage layer on below grade foundation walls in accordance with Section 9.14.

  1. Provision of the Building Code

Sentence Foundation Wall Drainage

(2.1) The drainage layer required in Sentence (2) shall be provided by

  1. not less than 19 mm mineral fibre insulation with a density of not less than 57 kg/m3;
  2. not less than 100 mm of free drainage granular material; or,
  3. a system which can be shown to provide equivalent performance to that provided by the materials described in Clauses (a) or (b).

  1. Applicant's Position

The applicant stated that HITEK 20 Cordrain has been properly evaluated and in fact accepted as meeting Clause and other Building Code provisions intended to keep basements dry.

  1. Chief Building Officials Position

The respondent stated that there was insufficient information to determine if the product provided equivalent performance to the materials specified in Clause & (b). The material should be evaluated by the Canadian Construction Materials Centre.

  1. Commission Ruling:

In favour of the Applicant. It is the decision of the Building Code Commission that the use of HITEK 20 Cordrain as a drainage layer on below grade foundation walls shows sufficiency of compliance with the Building Code.

  1. Conditin:

The foundation walls shall be dampproofed or waterproofed in accordance with Section 9.13 of the Building Code.

  1. Reasons:

The "Demonstration of Full Height Basement Insulation Construction Methods" report prepared for the Ontario Home Builders' Association by Buchan, Lawton, Parent Limited tested a similar product and found it provided equivalent performance as 19 mm mineral fibre insulation and 100 mm of free drainage granular material.

Dated at Toronto, this 30th day, in the month of September, in the year 1994, for application number 1994-37.
