Product highlights
Fully vulcanised EPDM
A flexible rubber waterproofing sheet with high elongation, supplied without a self-adhesive layer.
Weathering resistance
Resistance to weathering, ultraviolet radiation and ozone, with tested performance documented in the technical data sheet.
Long-term durability & heat-ageing resistance
Built for lasting waterproofing, with heat-ageing performance documented in the TDS. Actual service life depends on system design, installation, exposure and maintenance.

Product overview
Uses and installation options
WP-MEM-000001 is a fully vulcanised black EPDM rubber sheet without a self-adhesive layer. Use it for roof and basement waterproofing or pond and artificial-lake lining, subject to the project requirements.
Select a fully adhered, ballasted or mechanically fixed assembly. For concrete, agree surface preparation and the supporting components. For other substrates, including metal, ask us to review the bonding or fixing arrangement. Roofs with pedestrian access need a protective assembly; pond projects need a review of water-contact suitability.
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 values do not establish performance for other thicknesses or guarantee each production batch.
| Property | Test condition | Measured value or result |
|---|---|---|
| Tensile strength | 23 °C | MD 11.5 MPa; TD 12.8 MPa |
| Elongation at break | 23 °C | MD 556%; TD 566% |
| Tear strength | MD / TD | MD 30 kN/m; TD 30 kN/m |
| Watertightness | 0.3 MPa for 30 min | No leakage |
| Low-temperature flexibility | −40 °C | No cracking |
Download the English TDS, Rev.02 for the full test conditions and results, including ageing and chemical exposure. Test temperatures do not define the installation or service temperature range.
Preparing the seams
Use compatible butyl lap tape and primer, then press the joint with a hand roller. Before work starts, agree the lap dimensions, substrate preparation and adhesive or fixing requirements for the selected system. Follow the project installation specification for the complete assembly.
Handling and storage
- Store rolls flat on dry, level ground in a ventilated area, no more than five rolls high.
- Keep packaging intact and protect rolls from cuts, impact and direct sunlight.
- Keep away from fire and open flames. Prevent contact with oils, acids, alkalis and organic solvents during storage and transport. The TDS alkali results apply to the stated test medium and conditions.
Dimensions are nominal unless a tolerance is stated. Allow for laps and cutting when calculating the number of rolls.
Ordering options
- Standard rolls
- All five standard thicknesses use a nominal 1.2 m width and 20 m length. Each roll provides 24 m² before lap and cutting allowances.
- Custom dimensions
- Request thicknesses from 0.8 to 5 mm, wider sheets or custom roll lengths. Send your dimensions and required tolerances so we can confirm the available combination.
- Packing and order quantities
- Standard rolls use woven bags. Send your specification, quantity and destination for other packing options, MOQ and lead time.
- Application requirements
- Include the substrate, installation method and any water-contact or performance requirements. Ask for samples and written warranty terms with your quote.

Questions before you order
How does this differ from self-adhesive EPDM?
This sheet has no adhesive backing. Select a bonding adhesive, ballast or mechanical fixing system for your project. For a membrane with a butyl adhesive backing, see WP-MEM-000002.
Can I use it for a fishpond or landscape pond?
Send the pond use and lining design so we can review water-contact suitability. The TDS does not establish fish-safety or drinking-water approval.
How do I join the sheets?
Use compatible butyl lap tape and primer, then press the seam with a hand roller. Agree the lap dimensions and component combination before installation.
Do the test results cover all thicknesses?
TDS Rev.02 reports results for the 1.5 mm × 1.2 m × 20 m specification. These are measured results, not guaranteed values for each batch or other thicknesses. Include any required acceptance values in your inquiry.
