Eco Waterproof · Root-Proof Composite Sheet
Patent
No. 0711994

Applicable Structures

  • Architecture : Rooftop gardens, landscaped decks above underground parking structures, etc.
  • Civil Engineering : Landscaped areas above underground expressways, eco-tunnels, and other underground structures.

Features

  • High root penetration resistance provided by a durable copper barrier layer.
  • Made with over 99% pure copper for reliable and long-lasting root barrier performance.
  • Copper tape at sheet joints provides a continuous root barrier layer.
  • The high-adhesion flexible gel waterproofing layer accommodates substrate movement and cracking, helping prevent delamination and membrane lifting.
  • Excellent adhesion to concrete and various other substrates.
  • Self-adhesive sheet joints require no heat application, simplifying installation and improving on-site work efficiency.
