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

ID	Code provision	Solution type
09-14-02-01-02-b-00	9.14.2.1.(2)(b) Foundation Wall Drainage	Acceptable

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.

The above opinion(s) is/are 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

Geo-Wrap

Product 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 dampproofing system of the product includes a range of accessories such as fasteners, washers and moulding strips to ensure correct application.

See Figure 1, Figure 2 and Figure 3 for installation details.

Product evaluated by the CCMC Indicates that the product from this manufacturing facility has been evaluated by the CCMC

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 A.
The product must be installed in accordance with the manufacturer’s instructions. In the event of conflict between the manufacturer’s instructions and this CCMC evaluation, the CCMC evaluation shall govern.
The product was evaluated for use against cast-in-place and concrete block foundations, and must cover the foundation wall from the top of the footing to the final grade.
Unit masonry walls and concrete walls shall have all holes and recesses sealed with mortar. The product must be installed on surfaces that are clean and dry and free of ice, snow, frost, dust, dirt, oil, grease, cracks, projections and depressions, loose particles and debris.
The Class A product is a drainboard manufactured by laminating a geotextile to a dimpled membrane to deliver the transient water, including heavy rainfall, to the footing drain.
The product has been evaluated for use in vertical applications in depths up to 3.7 m below grade for Type 2 products. 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 to guide water past the cold joint to a drainage pipe located outside of the footing at the bottom of the wall. 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 either Subsection 9.14.3., Drainage Tile and Pipe, or 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 with a positive slope leading surface water away from the building.
The product must be protected from exposure to ultraviolet (UV) light (sunlight) within a maximum of 30 days of its installation.
Class A products, with a geotextile facing the soil, must be backfilled before runoff water hits the geotextile (i.e. during a heavy rainfall) to prevent clogging of the filter by fine particles of the soil carried by the running water.
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. The compatibility of the geotextile with the backfilled soil must be investigated on a project-by-project basis if the backfilled soils is a non-cohesive silt (ML) or clay (CL) according to the Unified Soil Classification System (USCS), a uniform fine sand, or any gap-graded soil. Compliance with this Report does not free the project from requiring proper engineering design of the drainage system.
The performance of fixtures used to anchor the product in the wall was evaluated for a single anchor. It is the responsibility of the manufacturer to define the pattern and spacing of anchors, considering the anchor strength as well as site-specific issues such as the type of soil, how it will interact with the product, as well as the backfilling method used.
The top of the membrane and all vertical joints and terminations must be mechanically fastened with trims, moulding strips, termination bars or other accessories to prevent soil particles from entering behind the membrane. Overlaps or joints which are occasionally exposed to a head of water must be sealed to avoid water entry and associated dragging of soil particles between the membrane and the foundation wall. Accessories used to anchor the product are part of the evaluation.
The product label and/or packaging must be clearly identified with the following:
- manufacturer’s name or logo; and
- the phrase “CCMC 13579-R.”

Code Compliance via Alternative Solutions

Where a design differs from the acceptable solutions in Division B, then it should be treated as an "alternative solution." A proponent of an alternative solution must demonstrate that the alternative solution addresses the same issues as the applicable acceptable solutions in Division B and their attributed objectives and functional statements. However, because the objectives and functional statements are entirely qualitative, demonstrating compliance with them in isolation is not possible. Therefore, Clause 1.2.1.1.(1)(b) identifies the principle that Division B establishes the quantitative performance targets that alternative solutions must meet. In many cases, these targets are not defined very precisely by the acceptable solutions [...] Nevertheless, Clause 1.2.1.1.(1)(b) makes it clear that an effort must be made to demonstrate that an alternative solution will perform as well as a design that would satisfy the applicable acceptable solutions in Division B—not “well enough” but “as well as.”

National Building Code of Canada, Sentence A-1.2.1.1.(1)(b)

The CCMC has determined that compliance with this provision of the Code has been demonstrated as an Alternative Solution. The evaluation report provides a summary of the basis of CCMC's compliance opinion.

CCMC's code compliance opinions

All CCMC evaluation reports are opinions of code compliance established in accordance with the National Building Code of Canada, Subsection 1.2.1. "Compliance with this Code," which requires compliance to be achieved by:

complying with the applicable acceptable solutions in Division B, or
using an alternative solution that will achieve at least the minimum level of performance required by Division B in the areas defined by the objective and functional statements attributed to the applicable acceptable solutions.

The CCMC assesses compliance with Canadian building, energy and safety codes, and is trusted by over 6,000 regulators across Canada.
