Product information

Product name

TREMdri™ 540

Product description

The product is a self-adhered modified bituminous membrane intended to be used for waterproofing below-grade ICF foundation walls. The membrane consists of a styrene-butadiene-styrene (SBS) modified bitumen to which a tri-laminated woven polyethylene film is laminated. A silicone release film is applied on the other side of the membrane to facilitate installation. The membrane has vertical overlap markings to help installers achieve the required overlap at the seams. The membrane is available in two grades, which are made of different modified bituminous blends: the regular grade for the summer (S/E) and the cold-weather grade for the winter (W/H).

The membrane is installed after applying the manufacturer’s recommended primer over the foundation wall (ICF substrate).

The summer and winter grade membranes are manufactured in rolls that measure 22.9 m long × 0.91 m wide. The membrane is 1.0 mm thick for both grades.

  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.

  • Use of the product has been evaluated for applications falling under the scope of Part 9, Housing and Small Buildings, of the NBC 2015. The ICF foundation walls must meet the structural requirements of the NBC 2015.
  • While the waterproofing continuity of the membrane to other parts of the wall (slabs, footing, etc.) is beyond the scope of this evaluation, the installer must follow engineer-approved solutions to provide the waterproofing continuity (i.e., an overall waterproofing system that will perform under the building site conditions).
  • The maximum hydrostatic pressure that the membrane and seams can sustain is 60 kPa.
  • The membrane rolls must be stored vertically on site at less than the maximum temperature recommended by the manufacturer and must be protected from exposure to ultraviolet (UV) radiation in accordance with the manufacturer’s instructions.
  • Prior to the application of the membrane, the following conditions and limitations related to the ICF must be followed:
    • The product evaluation is limited to installation over ICFs that comply with the applicable requirements of the NBC 2015, or that are evaluated by the CCMC.
    • The ICFs must be made of Type 2 (or greater) moulded expanded polystyrene (EPS) having a completely flat surface, or a flat surface including channels not wider than 4.8 mm and not deeper than 1 mm covering a maximum of 10% of the surface area.
    • The ICFs used to build the foundation wall corners must be of one piece (a prefabricated corner) in order to avoid vertical joints along the foundation wall corners. If prefabricated corners cannot be used, the vertical joints must be finished in accordance with the manufacturer’s recommendations with material compatible with the ICF and the membrane.
    • The vertical and horizontal joints between the ICFs must not be larger than 3 mm. The connectors embedded in the ICFs must not be visible on the exterior surface of the EPS.
    • The poured-in-place concrete must reach its 7-day strength prior to application of the membrane.
    • The membrane manufacturer must recommend appropriate material that is compatible with the membrane and the ICF to fill surface irregularities and cracks in the ICFs, gaps between the ICFs, and gaps between the ICFs and the footing.
    • The ICFs must have a smooth surface to prevent air pockets from forming between the ICF and the membrane.
    • The ICF surface must be cleaned, dried and primed with TREMprime ICF™ Primer prior to the installation of the membrane in accordance with the manufacturer’s installation instructions. ICF walls must meet the surface preparation requirements of Article 9.13.3.3., Preparation of Surface, of Division B of the NBC 2015.
    • If the surface of the ICF is damaged (e.g., discoloured, chalked) by UV radiation, it must be rasped and cleaned in order to bring it back to its original condition.
    • The ICFs should not be exposed to UV radiation for more than three weeks.
  • During the membrane installation, the following conditions and limitations must be followed:
    • The minimum outdoor air temperature during installation of the membrane is 5°C for the winter grade and 10°C for the summer grade. When the membrane is subjected to cold temperatures, the outdoor air temperature is similar to the membrane surface temperature (which is equivalent to the temperature at the interface between the membrane and ICF). For installation of the membrane in temperatures colder than 5°C for the winter grade and 10°C for the summer grade, proper and good techniques such as protection of materials, enclosing work areas, etc., must be followed to ensure the evaluated performances.
    • When the membrane is subjected to hot temperatures, the membrane interface temperature does not necessarily correspond to the outdoor air temperature, especially where the sun hits the membrane. On construction sites during hot summer days, the interface temperature can reach 70°C, while the outdoor air temperature is only around 35°C. For proper adhesion of the membrane during summer conditions, measures must be taken on site to ensure that the surface temperature (which is equivalent to the interface temperature) of both grades of the membrane is maintained below 40°C. The approximate temperature of the membrane surface can be determined using an infrared thermometer held about 600 mm from the wall. Temperature measurements must be taken on all sides of the building since wind and sun exposure will vary and, thus, influence the temperature. Where the membrane is exposed to the sun, the operator of the thermometer should cast a shadow in front of the membrane and quickly take a measurement in the shaded area at about 600 mm from the wall. The membrane must be protected if the temperature is higher than 40°C.
    • A minimum 5-kg force must be applied with a roller over the entire membrane surface, including the seams, to ensure full contact and adhesion of the membrane with the ICFs. A minimum of two passes must be performed.
    • The minimum width of the membrane overlap at the joint must be 75 mm.
    • The membrane installation must stop at grade level. The exposed above-grade portion of the membrane after soil settling must be protected from UV radiation and mechanical impact with additional backfill that would be graded away from the foundation.
    • The thickness of the membrane installed on-site must be equivalent to the thickness of the evaluated product, which is 1.0 mm.
    • The top edges (terminations) of the membrane must be sealed with a bead of mastic or an equivalent performing solution in compliance with the manufacturer’s instructions.
  • The peel adhesion performance of the membrane was assessed only over two substrates: ICF and concrete. See Table 4 and Table 5.
  • Following its application, the entire membrane must be protected from exposure to UV radiation within three weeks of its application and in accordance with the manufacturer’s additional recommendations.
  • Prior to backfilling, the following conditions and limitations must be followed:
    • The membrane must first be inspected for any defects (holes, tears, etc.), which must be repaired in accordance with the manufacturer’s instructions.
    • The membrane must be covered with a protection board, which may consist of a semi-rigid or rigid board with a smooth surface facing the membrane (e.g., mineral fibre boards, EPS/XPS boards or equivalent). The protection boards must not be installed using fasteners, in order to avoid penetrations through the membrane. See the manufacturer’s recommendations regarding the use of adhesive and tape to secure the protection boards. Clean sand backfill can be used as an alternative solution to protection boards.
  • The foundation wall must be backfilled in accordance with the requirements of Subsection 9.12.3., Backfill, of Division B of the NBC 2015.
  • When used in soils containing high levels of organic matter, chemicals and microbiological activity that will affect the products’ performance, the manufacturer must be consulted to determine suitability.
  • The products must be applied by qualified installers who will follow the CCMC conditions and limitations on the products and the manufacturer’s installation instructions.
  • The products must be identified with the phrase “CCMC 14095-R.”
