Epdm Rubber Sheet For Basement Underground Waterproofing

Excellent weathering and aging resistance, UV‑resistance and ozone‑resistance. Suitable for direct exposed application, long service life outdoor, resistant to pulverization and cracking.
High elasticity and high elongation, high tensile strength. Accommodates substrate expansion, contraction, settlement and micro‑cracks with good crack‑bridging performance.
Outstanding high‑low temperature resistance. Remains flexible at ‑40℃, no softening under high temperature. Fits cold and hot climate zones.
Good resistance to acid, alkali and corrosion. Tolerates salt‑spray, sewage and mild chemical media, ideal for coastal and corrosive‑environment projects.
Light‑weight to reduce roof load. Cold installation available; multiple construction methods: full bonding, loose‑lay, dot bonding, strip bonding. Easy maintenance in later stage.
Good root‑puncture resistance, applicable for green roof waterproofing.
