Compliance opinion

It is the opinion of the Canadian Construction Materials Centre that the evaluated product, when used as a material for dampproofing in accordance with the conditions and limitations stated in this evaluation, complies with the following code:

National Building Code of Canada 2015

ID Code provision Solution type
09-13-02-00-00-0-009.13.2. DampproofingAlternative

Ontario Building Code

Ruling No. 14-20-315 (13673-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 2014-10-27 (revised 2021-12-13) 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.

Product information

Product name

Hydrostar AG (Dampproofing)

Product description

The product is a black, high-density, polyethylene, quasi-rigid plastic sheet membrane extruded in a manner that results in a dimpled surface  on one side and a flat surface on the other. The dimpled surface is intended to provide an air gap between the wall and the adjacent soil. The product is produced from a mixture of virgin and recycled plastic materials. The product has dimples that are 7 mm high and is available in rolls that are 0.82 mm thick (the flat, i.e., non-dimpled area), 20 m long, and either 2.4 m, 2.1 m, 1.98 m, 1.8 m, 1.5 m or 1.2 m wide.

To ensure correct application, a range of accessories, such as fasteners, washers, plugs, and moulding strips, is included with the product.

  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 products have been classified as “Type 2” for use in vertical applications 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 evaluation.
  • The products must be installed in accordance with the manufacturer’s instructions. In the event of conflict between the manufacturer’s instructions and this Report, this Report shall govern.
  • The products were evaluated for use against cast-in-place and concrete block foundations only and must cover the foundation wall from the top of the footing to the final grade.
  • The products must be used in locations where the foundation wall is well-drained in accordance with Subsection 9.14.2., Foundation Drainage, of Division B of the NBC 2015.
  • The products are dimpled membrane drainage systems 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 wall’s surface.
  • The products must be protected from exposure to ultraviolet (UV) light (sunlight) within a maximum of 30 days of installation.
  • Long-term performance of the dampproofing system depends 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 considerations. Compliance with this Report does not exempt the project from requiring proper engineering design of the drainage system.
  • The performance of fixtures used to anchor the products 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 products, 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’s label and/or packaging must be clearly identified with the following:
    • manufacturer’s name or logo; and
    • the phrase “CCMC 13673-R.”
