It is the opinion of the Canadian Construction Materials Centre that the evaluated products, when used as a foundation wall drainage material in accordance with the conditions and limitations stated in this evaluation, comply with the following code:
Ontario Building Code 2017
|ID||Code provision||Solution type|
|09-14-02-01-02-b-00||220.127.116.11.(2)(b) Foundation Wall Drainage||Acceptable|
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.
- Isostud GEO T
- Powerdrain Plus
The product is a high-density polyethylene (HDPE), semi-rigid, thermally formed sheet that is smooth on one side and dimpled on the other to provide an air gap between the membrane and the wall surface. The product also has an attached polypropylene geotextile mat on the dimpled side. The overall thickness is 8.66 mm with a sheet thickness of 0.025 mm and a hollow core thickness of 8.02 mm. The product is available in rolled sheets 2.44 m (8 ft.) wide by 15.24 m (50 ft.) long.
To ensure correct application, a range of accessories (such as anchors and moulding strips) is included with the product. Photos of the product and anchor accessory are below.
This evaluation is valid only for products produced at the following plant:

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 has been classified as Type 2, Class A based on the evidence provided.
- The product must be installed in accordance with the manufacturer’s instructions.
- The product was evaluated for use against cast-in-place and concrete block foundations only.
- The product is a dimpled membrane drainage product designed to act as a protective layer or a capillary breaking layer against the foundation wall to protect the wall against transient or intermittent water that may come in contact with the surface of the wall.
- The product has been evaluated for use in vertical applications at depths of 3.7 m below grade. 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, it 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 Subsection 9.14.3., Drainage Tile and Pipe, or to 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) radiation from 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 (e.g., 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 micro-organisms in the soil (i.e., iron ochre), as well as compatibility of the filter with the soil, among other issues. There should be a proper engineering design for the drainage system.
- The performance of fixtures used to anchor the product in the wall was evaluated for a single anchor. It is the manufacturer’s responsibility 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 and sealed to prevent soil particles from entering behind the membrane. Accessories used to anchor the product are part of the evaluation.
- The product must be labelled with the manufacturer’s name or logo and the phrase “CCMC 14053-R.”
This evaluation is based on demonstrated conformance with the following criteria:
