EPDM Waterproofing Membrane for Roofing and Civil Engineering Applications
Product Overview
EPDM waterproof membrane is a single-ply, flexible roofing and waterproofing sheet manufactured from ethylene-propylene-diene monomer (EPDM) synthetic rubber. The thermosetting rubber compound provides a seamless, highly elastic membrane that conforms to substrate movement without cracking.
The product addresses the need for durable, long-term waterproofing on exposed roofs, low-slope structures, and civil engineering projects where flexibility and resistance to extreme weather are priorities. Its rubber formulation provides exceptional elasticity, allowing the membrane to accommodate structural movement and thermal expansion without loss of integrity.
Typical installations include low-slope commercial and residential roofs, ballasted roofing systems, pond and reservoir liners, tunnels, and below-grade waterproofing applications.
Available in thicknesses from 1.0 mm to 2.0 mm, with roll widths from 1.0 m to 4.0 m and roll lengths from 10 m to 20 m as standard. Custom sizes and widths are available subject to production feasibility. Our team reviews drawings solely to assess production feasibility and does not undertake engineering design or system selection.
Product Features
High elasticity and flexibility
The rubber formulation provides high elongation and elastic recovery, allowing the membrane to accommodate substrate movement, thermal expansion, and structural settlement without cracking or loss of integrity.
Weather and ozone resistance
EPDM offers resistance to UV radiation, ozone, and weathering. These are laboratory material-level properties; actual field performance depends on site conditions and complete system design.
Wide temperature tolerance
The membrane maintains flexibility at low temperatures and stability at elevated temperatures. These are laboratory material-level properties; actual on-site performance shall be evaluated by the project engineer according to local climate and installation conditions.
Easy installation
Available in both fully adhered and mechanically fastened systems. The membrane can be installed using adhesive or ballast, with seams sealed using factory-engineered tape or liquid adhesive. Suitable installation method shall be confirmed by project design.
Surface and Finish Options
EPDM waterproof membrane is available in various surface finishes. Available options include:
| Option Type | Description |
|---|---|
| Smooth (Standard) | Smooth black rubber surface; suitable for most exposed and non-exposed applications |
| Textured | Textured surface for improved slip resistance on slopes |
| Fleece-Backed | Polyester fleece laminated to underside for adhesive bonding in fully adhered systems |
| Self-Adhesive | Peel-and-stick backing for quick installation without liquid adhesives |
