Waterproof membranes
Galleries and tunnels
| Acts as a waterproof membrane to prevent leaks |
| Provides high mechanical strength for long-term performance |
| Available in widths up to 2.2 m and thicknesses up to 12 mm |
| UV-resistant for outdoor and exposed environments |
| Transparent options allow safe, precise welding and inspection |
In underground construction, waterproofing is essential to protect galleries and tunnels from water infiltration and structural damage.
Flexible PVC membranes provide a reliable barrier against moisture while offering the mechanical strength needed to withstand demanding conditions.
Transparent membrane options make it easier to perform safe, accurate welding and visual inspections, while opaque membranes ensure complete coverage in light-sensitive areas.
With a wide range of thicknesses and widths, Extruflex membranes can be adapted to suit large-scale tunnel projects or more confined gallery spaces. These solutions help extend the lifespan of infrastructure, improve safety, and reduce costly maintenance.
