Multi Purpose Bitumen Membrane for Tunnel Lining with High Puncture Resistance

Yes, absolutely. While our standard thicknesses are 3mm, 4mm, and 5mm, we support full customization. We can manufacture thicknesses ranging from 2mm to 5mm according to your project's specific engineering requirements or local building standards. Please contact our team with your detailed specifications.

Yes, our SBS membrane is designed for high installation efficiency and safety. For the torch-applied version, the bottom PE film features a special melt-indicator pattern that tells workers exactly when the bitumen is ready to bond, preventing over-heating. We also offer a self-adhesive variant that requires no open flame, making it 100% flame-free and incredibly safe for confined or high-risk spaces.

Yes. Thanks to the high-grade SBS (Styrene-Butadiene-Styrene) modifier and the heavy-duty polyester core, our membrane maintains excellent low-temperature flexibility down to -20 C / -25 C. It will not crack or become brittle during winter installation, ensuring a safe and reliable seal year-round.

It depends on your application: PE Film / Fine Sand: Best for non-exposed roofing, basements, and underground projects where another layer (like concrete or gravel) will cover the membrane. Mineral Granules (Granular Surface): Best for exposed roofs. The granules protect the bitumen from UV radiation and mechanical damage, while also offering an aesthetic finish.

The basic equipment required is very standard and easy to source: a propane gas torch with a connecting hose, a gas cylinder, a pressure regulator, a cutting knife, and a heavy roller or trowel to press the seams. The straightforward process helps save on labor costs and shortens the project timeline.
