  • Civil engineering : Underground structures including railways, power plants, sewage treatments, utility tunnels, and underground roads
Uniqueness of the Method
01. Korea’s first root barrier sheet technology! [New Technology No. 560]

It uses Tray from copper obtained in agriculture to prevent root growth.

More small roots, low root development

02 Eco Root Barrier Sheet made with Copper’s excellent long-term life through oxide film and high resistance against corrosion

CU Root Barrier Sheet Durability

Approximately 24 years (*The thickness of the Root Barrier Sheet is 0.035mm)

Strong resistance against corrosion even in salty and humid areas

03. Integration of Waterproofing and Root Prevention!

It reacts in an adhesive, flexible and semi-permanent manner to the movement of the building, while at the same time preventing any root penetrations.

Eco Sealis an eco-friendly, highly adhesive and flexible waterproofing coating material that does not use any solvents that meets the VOCs standards.
