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

Platon®Foundation Wrap

Product description

The product is a carbon-compounded, high-density polyethylene membrane with a dimpled surface on one side to provide an air gap between the concrete wall and the adjacent soil.

The product features double cone dimples, which are 6 mm high, spaced at about 30 mm on centre (o.c.) and joined by channels. The product is available in rolls that are 0.6 mm thick, 20 m long, and up to 3.05 m wide.

To ensure correct application, the manufacturer offers a complete dampproofing system with compatible and durable fasteners, sealants and accessories where needed. The configuration of the system is shown in Figure 1, Figure 2Figure 3 and Figure 4.

  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 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 product must be installed in accordance with the manufacturer’s instructions. In the event of conflict between the manufacturer’s instructions and this evaluation, this evaluation shall govern.
  • The product was 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 product 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 product is a dimpled membrane dampproofing system 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 product must be protected from exposure to ultraviolet (UV) light (sunlight) within a maximum of six months 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 issues. Compliance with this evaluation does not exempt 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 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 12266-R.”
