EPDM Waterproof Membrane

The EPDM Waterproof Membrane supplied by Shandong Qiaozhou Import & Export Co., Ltd. is a synthetic rubber sheet designed for long-term waterproofing in construction. It has a standard thickness range of 1.2 mm to 2.0 mm and a width of 1.0 m to 1.5 m, with rolls typically 20 m in length. The material is formulated from ethylene-propylene-diene monomer rubber, offering inherent resistance to weathering, ozone, and UV exposure without the need for protective coatings.

This membrane is typically reinforced with polyester scrim for dimensional stability and tensile strength, with elongation values commonly between 250% and 400% at break. It exhibits low-temperature flexibility down to -40°C and can withstand continuous exposure to temperatures up to 120°C. The product is available in both self-adhesive and torch-applied variants, with the adhesive layer usually made from modified bitumen or acrylic-based compounds. These properties align with standard industry expectations for EPDM in roofing and below-grade applications.

Buyers commonly use this membrane for flat roofs, foundation walls, and water-retaining structures such as ponds and reservoirs. It is preferred by commercial contractors and civil engineering firms seeking durable, low-maintenance solutions. Packaging is in heavy-duty polyethylene with cardboard cores, shipped in standard 20 ft containers. Trade terms include FOB Qingdao or Shanghai, with payment via T/T or L/C. MOQ and lead time must be confirmed directly with the supplier.
