Overview

50 years of service life. Proven in extremes.

EPDM Rubber Membrane is a single-ply waterproofing membrane manufactured from vulcanized ethylene propylene diene monomer rubber. Unlike thermoplastic alternatives, EPDM is a thermoset – once vulcanized, it cannot be re-melted, giving exceptional long-term dimensional stability and UV resistance.

The premium choice for exposed roof, water tank, and pond applications where 30–50 year service life is required. Suitable for high-end residential and infrastructure projects.

Key Features

  • Vulcanized synthetic rubber – exceptional long-term durability
  • Outstanding UV, ozone, and weathering resistance
  • 300%+ elongation accommodates structural movement
  • Wide sheet sizes minimize seams
  • Service temperature −40°C to +120°C
  • Recyclable at end of service life
