Double‑sided Baseless Self‑adhesive Modified Bitumen Waterproof Membrane, for utility tunnels and metro side walls.

Product Introduction

Product Features

• Non‑reinforced structure provides excellent overall flexibility and bending resistance. It accommodates minor substrate deformation and cracking with good anti‑water‑channeling performance.
• Double‑sided self‑adhesion enables bonding on both sides, achieving full adhesion between membrane‑substrate and membrane‑structural layer for superior sealing performance.
• Cold construction without open‑fire torching, safe and eco‑friendly, easy operation and high construction efficiency.
• High bonding strength of modified asphalt adhesive, firmly adheres to concrete and cement mortar substrates with low delamination risk.
• Excellent high‑low temperature resistance: no brittle cracking at low temperature and no flowing at high temperature. Good water and corrosion resistance for long service life.
• Self‑adhesive sealing for overlapping edges ensures reliable joints and reduces leakage risks.

Application Scope

• Underground works: waterproofing and anti‑seepage for basement floors, side walls, roof slabs, underground garages and civil air‑defense projects.
• Building roofs: non‑exposed waterproofing for flat and sloped roofs, renovation of new and existing roofs.
• Interior works: waterproofing for wet areas such as bathrooms, kitchens and balconies.
• Structures: municipal waterproofing for pools, water channels, tunnels and utility tunnels.
• Can be used as intermediate waterproof layer in composite waterproofing systems in combination with other waterproof materials.
