Waterproofing membranes

Self-adhesive EPDM waterproofing membrane

EPDM membrane with a reactive butyl adhesive backing and removable release film. Four nominal thicknesses in 1.2 m × 20 m rolls for use on compatible concrete, mortar and metal surfaces.

Material
EPDM
Thickness options
1.2, 1.5, 1.8, 2 mm
Width options
1.2 m
Applications
Basement walls & roof decks, Non-traffic concrete roofs, Compatible metal surfaces

Product highlights

  1. Self-adhesive construction

    A reactive butyl adhesive layer on one side bonds the membrane to a prepared, compatible substrate. A removable release film protects the adhesive before application.

  2. Flexible EPDM layer

    Fully vulcanised EPDM rubber provides high elongation, with measured tensile and elongation results documented for the tested 1.5 mm specification.

  3. Weathering resistance

    Resistance to weathering, ultraviolet radiation and ozone, with heat-ageing and ozone test results available in the technical data sheet.

Product overview

Uses and construction

WP-MEM-000002 combines a fully vulcanised EPDM sheet with a reactive butyl self-adhesive layer on one side. A removable release film protects the adhesive. Use compatible jointing and detailing materials to complete the installation.

The product is intended for basement walls and roof decks, non-traffic concrete roofs and compatible metal surfaces. For basement slabs or roofs with pedestrian access, agree the protective assembly and detailing before selecting the membrane.

The EPDM sheet resists weathering, ultraviolet radiation and ozone. See the TDS for test conditions and results for the 1.5 mm specification.

Test results for the 1.5 mm specification

The TDS reports these results for the 1.5 mm × 1.2 m × 20 m specification under GB/T 18173.1-2012. MD means longitudinal direction; TD means transverse direction. The results do not establish performance for other thicknesses or guarantee production-batch values or adhesion on site.

Property Test condition Measured value or result
Tensile strength 23 °C MD 9.9 MPa; TD 10.3 MPa
Elongation at break 23 °C MD 622%; TD 648%
Tear strength MD / TD MD 31 kN/m; TD 33 kN/m
Watertightness 0.3 MPa for 30 min No leakage
Low-temperature flexibility −25 °C No cracking
Peel strength: sheet to sheet Standard test conditions 0.9 N/mm
Peel strength: sheet to aluminium Standard test conditions 1.2 N/mm
Peel strength: sheet to cement mortar board Standard test conditions 1.1 N/mm

Application requirements

Check compatibility with the concrete, cement mortar or metal surface, including any coating. Agree substrate preparation, primer requirements and lap dimensions before installation.

  1. Position the membrane, remove the release film and press the butyl adhesive face onto the prepared substrate.
  2. For joints using butyl lap tape, apply a compatible primer and press the seam with a hand roller.

Follow the project installation requirements for details, protection and site conditions.

Handling and storage

  • Store rolls flat on dry, level ground, no more than five rolls high.
  • Protect rolls from impact, cuts and direct sunlight. Keep transport packaging intact.
  • Prevent contact with acids, alkalis, oils and organic solvents during storage and transport. Alkali test results apply to the stated medium and conditions.
  • Keep away from fire and open flames.

Dimensions are nominal unless a tolerance is stated. Allow for laps and cutting when calculating the number of rolls.

Ordering options

How sourcing works
Four standard thicknesses
Choose a nominal thickness of 1.2, 1.5, 1.8 or 2.0 mm. All four use a standard 1.2 m width and 20 m length, providing 24 m² per roll before overlap and cutting allowances.
Colour requirements
Special EPDM surface colours can be discussed. Confirm the available surface and adhesive colour combinations, thickness, MOQ, lead time and applicable performance for your request.
Packaging and delivery
Use woven-bag packaging with one roll / 24 m² per package. Export packing, weights, MOQ and lead time are agreed with the quotation.

Questions before you order

Which applications should I discuss with you?

Basement walls and roof decks, non-traffic concrete roofs and compatible metal surfaces. Basement slabs and roofs with pedestrian access require a suitable system and protective assembly.

Does the adhesive backing replace seam materials?

The backing bonds the sheet to the substrate. For joints using butyl lap tape, use a compatible primer and hand roller. Ask us to review the lap detail and any main-area primer requirement for your project.

Do the test results cover every thickness?

TDS Rev.01 covers the tested 1.5 mm × 1.2 m × 20 m specification. The results do not establish performance for other thicknesses or guarantee adhesion on site. Specify any required performance values in your inquiry.
