Originality of the construction method

01. Korea's First New Root-Proof Technology! [New Technology No. 560]

Use of Copper [Cu] Trays in Agriculture (Inhibition of Cardiac Growth)
* Research Paper: “Effects of Copper-Coated Plug Trays on Enzymes and Post-Transplant Growth of Cabbage Authors – Yong Young-rok et al.

Untreated Tray
Few fine roots, Severe myocardial development

Copper [Cu] Tray
Many fine roots, poor myocardial development


02. Excellent long lifespan due to oxide film formation Long-term corrosion resistance of copper (Cu) root barrier sheets

Durability of Copper [Cu] Root Barrier Sheet

  • Minimum approximately 24 years (*Copper film thickness of copper root barrier sheet: 0.035mm)
  • Exhibits strong corrosion resistance even in saline and humid regions

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

Applicable Structures

  • Architecture - Rooftop landscaping, underground parking lot upper park projects, etc.
  • Civil Engineering - Underground expressway upper park projects, ecological tunnels, etc.

Features

  • As a metal-based material, it has high surface hardness, preventing root penetration.
  • Since the copper membrane is composed of over 99% pure copper, it offers excellent root resistance.
  • Joint treatment using copper tape ensures an integrated copper surface.
  • The high-adhesion gel waterproofing material, possessing flexible adhesive properties, prevents interfacial detachment during movement or cracking, exhibiting crack-following capabilities and minimizing lifting phenomena.
  • Due to its high adhesiveness, it adheres well even to dissimilar materials other than concrete.
  • In treating the joints between sheets, the method involves self-adhesion through direct lamination (adhesion) rather than using a hot method. This simplifies construction, allowing even unskilled workers to perform the work.
