1. Opinion

It is the opinion of the Canadian Construction Materials Centre (CCMC) that “Geo-Wrap”, when used as dampproofing for basement walls in accordance with the conditions and limitations stated in Section 3 of this Report, complies with the National Building Code 2010:

  • Clause 1.2.1.1.(1)(b), Division A, as an alternative solution that achieves at least the minimum level of performance required by Division B in the areas defined by the objectives and functional statements attributed to the following applicable acceptable solutions:
    • Sentence 9.13.2.2.(1) Material Standards (required dampproofing)

This opinion is based on CCMC's evaluation of the technical evidence in Section 4 provided by the Report Holder.

Ruling No. 13-05-296 (13579-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 2013-07-12 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.

2. Description

The product is a high-density polyethylene, quasi-rigid plastic sheet membrane that is extruded in such a way as to result in a smooth surface on one side and a dimpled surface on the other (dimples are 5 mm deep) to which a heat-bonded geo-textile is attached.

The product is available in rolled sheets that are 0.6 mm thick, 15 m long and 1.07 m to 3.0 m wide.

The product's dampproofing system includes a range of accessories such as fasteners, washers and moulding strips to ensure correct application.  See Figures 1 and 2 for installation details.

3. Conditions and Limitations

CCMC's compliance opinion in Section 1 is bound by the “Geo-Wrap” being used in accordance with the conditions and limitations set out below.

  • The product has been evaluated for use against cast-in-place and concrete block foundations only.
  • The product must be used in locations where the foundation wall is well drained in accordance with Subsection 9.14.2., Foundation Wall Drainage, of Division B of the NBC 2010.
  • The product must be installed in accordance with the manufacturer's instructions and be protected from exposure to ultraviolet radiation from the sun within 30 days of its installation.
  • The product has been evaluated for use 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 Report.
  • The product must cover the foundation wall from the top of the footing to the final grade.
  • The top of the membrane and all vertical joints and terminations must be mechanically fastened and sealed.
  • As the dampproofing membrane does not have to adhere to the surface and can permanently bridge any normal joint, tie hole, fault or shrinkage crack, the wall surface does not have to be parged, cleaned, patched or sealed before hanging the membrane.
  • The product label and/or packaging must be clearly identified with the following:
    • manufacturer’s name or logo; and
    • the phrase “CCMC 13579-R”.
