In waterproofing engineering construction, we mostly encounter waterproofing materials with a width of 1 meter. Materials wider than 1 meter are relatively rare, although 2-meter-wide materials do exist. However, waterproofing materials exceeding 3 meters in width are quite uncommon. So, are there manufacturers producing EPDM rubber waterproofing membranes wider than 3 meters? Yes, Henan Yuecheng Waterproofing Materials Co., Ltd. can produce EPDM rubber waterproofing membranes with widths exceeding 3 meters.

I. Product Introduction
EPDM rubber waterproofing membrane is a homogeneous, high-performance single-layer synthetic polymer rubber waterproofing membrane. It is primarily made from ethylene propylene diene monomer (EPDM) rubber, supplemented with reinforcing agents, plasticizers, anti-aging agents, vulcanization accelerators, and other processing aids. The manufacturing process includes mixing, cooling, filtering, sulfur addition, extrusion, pressurized continuous vulcanization, inspection, and packaging.
II. Product Features
1. A specially modified molecular structure effectively addresses the shortcomings of EPDM adhesive lap joints currently found domestically and internationally;
2. Long service life, anti-aging properties, with roofing materials lasting over 20 years and underground applications up to 50 years;
3. High elongation, relatively high tensile strength, and minimal dimensional changes under heat treatment;
4. Excellent resistance to root penetration, making it suitable for green roof waterproofing layers;
5. Good low-temperature flexibility and adaptability to environmental temperature changes;
6. Easy construction, strong and reliable lap joints, and no environmental pollution;
7. Resistant to chemical corrosion, suitable for special applications;
8. Easy maintenance and low cost;
9. Convenient detailing;
10. Good puncture resistance.
III. Scope of Application
Suitable for waterproofing projects in industrial and civil building roofs and underground structures, water reservoirs, municipal, subway, and tunnel engineering. Particularly ideal for key waterproofing projects requiring high durability, corrosion resistance, and adaptability to deformation.
IV. Product Specifications
1. Product thickness: 1.0mm, 1.2mm, 1.5mm, 2.0mm
2. Standard widths: 1m, 3m, 5m, 6m, 9m, 12m
3. Standard lengths: 20m, 30m, 50m
Note: Custom specifications are available based on user requirements. Standard widths are 1 meter or 1.2 meters, but EPDM rubber waterproofing membranes with widths ranging from 3 meters to 10 meters can also be custom-produced. Please contact Henan Yuecheng Waterproofing Materials Co., Ltd.
