Tunnels and Underground

THE CHALLENGE

Underground tunnels are created to serve demanding projects i.e. to support road highways that cut through mountains. Due to the existence of ground water, tunnel walls are typically lined with waterproof membrane layers which require high protection from potential damage that can be caused by construction operations.

THE SOLUTION

Thrace Group PNW Needle-punched Nonwoven geotextile series can be used as protective layers for lining systems, offering superior mechanical properties of tensile strength/elongation, static puncture as well as perforation resistance.

THE BENEFITS

  • High protection of waterproof membrane
  • Long-term resistance to alkaline media
