Product information

Product name

Hygrothane

Product description

The product is a cold, spray-applied, polyurea membrane system consisting of two liquid components mixed during application that when cured form a seamless, monolithic waterproofing membrane. The first component is a Special Pre-Polymer ISO and the second component is a Reactive Polyamine Crosslinker. The product is intended to be used as a waterproofing membrane. The product is intended to be installed on poured concrete or concrete block wall substrates of below-grade foundation wall systems.

The spray-applied membrane is applied by the manufacturer’s qualified installers to a thickness 1.27 mm (50 mil) in accordance with the manufacturer’s instructions.

  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 scope of this evaluation is for applications falling under the scope of Part 9, Housing and Small Buildings, of Division B of the NBC 2015. The foundation walls must meet the structural requirements of the NBC 2015.
  • The maximum hydrostatic pressure that the membrane can sustain is 48 kPa for 5 days.
  • The poured-in-place concrete wall must be cured to a maximum measured moisture content of 20% and the outside temperature shall not be below –5°C prior to the application of the product.
  • Unit masonry or poured-in-place concrete walls must meet the surface preparation requirements of Article 9.13.3.3., Preparation of Surface, of Division B of the NBC 2015.
  • The chemicals (Part A and B of the waterproofing system) must be stored on site in accordance with the manufacturer’s recommendations.
  • The thickness of the membrane installed throughout the foundation wall must meet the minimum thickness of the evaluated product.
  • While the waterproofing continuity of the membrane to other parts of the wall (e.g., slabs, footing) is beyond the scope of this evaluation, the installer must follow manufacturer-approved solutions to provide the waterproofing continuity.
  • This evaluation only covers the spray-applied installation of the membrane.
  • Patching materials used to fill voids in the substrate wall system must be compatible with the substrate and the membrane.
  • During application of the membrane, the manufacturer’s recommendations must be followed to ensure risks associated with exothermic reactions and subsequent fire risks are eliminated.
  • Following its application, the entire membrane must be protected from exposure to ultraviolet (UV) radiation within six weeks of its application and in accordance with the manufacturer’s additional recommendations.
  • The exposed above-grade portion of the membrane after soil settling must be protected from UV radiation with a compatible exterior top coat paint finish or flashing for in-service UV protection or additional backfill to protect the membrane that would be graded away from the foundation.
  • The use of the product is limited to installation over foundation walls facing normal soil conditions. When used in soils containing high levels of organic matter, chemicals or microbiological activity, the manufacturer must be consulted to determine suitability.
  • Prior to backfilling:
    • the membrane must be first inspected to detect any defects (e.g., holes, cracks, thin areas, bubbles) and be repaired in accordance with the manufacturer’s instructions, and
    • when applied at a minimum thickness of 55 mil, the membrane is impact-resistant and does not require the addition of a protection board as identified in Sentence 9.13.3.4.(3) of Division B of the NBC 2015.
  • The foundation wall must be backfilled in accordance with the requirements of Subsection 9.12.3., Backfill, of Division B of the NBC 2015.
  • The product must be applied by qualified installers in accordance with the manufacturer’s installation instructions using the recommended tools.
  • The product must be identified with the phrase "CCMC 14144-R."
