FLEXSEAL EPDM (Grade RM) is a non-reinforced cured single-ply EPDM waterproofing membrane (1.2mm thick, black, tensile strength 9.5 MPa, elongation 400%, angular tear 28 kN/m) providing superior roofing, waterproofing, and tanking protection with exceptional ozone/UV resistance, heat aging stability (post 670h@116°C: 92% strength retention), and brittleness point <-45°C. This premium FLEXSEAL EPDM solution delivers factory-seam strength causing sheet failure before seam peel, water absorption <1.7% (166h@70°C), and dimensional stability (-0.45% linear change).

ASTM D6134 Type I compliant membrane bonds permanently using Flexseal Bonding Adhesive (40mm overlaps) or seam tapes, maintaining flexibility across extreme temperature cycles while resisting punctures during installation/backfilling. Standard 1.2m width with factory seams for wider applications.
