High-Performance Anti-seepage Geotextiles for Tunnel Projects
Product Introduction
Hanging type tunnel is anew tunnel waterproof material developed by Jian-Yi, realizing nails construction pendant hang by one time, simplifying the difficulties of traditional waterproofing material in the tunnel construction, improving the laying efficiency and quality, shortening the construction period, greatly reducing the comprehensive cost, having strong competitive advantage.
Product series include: separate waterproof board, compound waterproof board.
* Separate waterproof board: geotextile and hanging belt geomembrane plate layered laid.
* Compound waterproof board: geotextile and geomembrane is compounded by overall, point, type compound, thebutt welds is kept, and equipped with geotextile hanging belt, can be overall laid and complete by one time.
Product Properties
* Excellent anti-seepage, high barrier property, puncture resistance;
* No chemical pollutants, acid and alkali resistance, various chemical substances resistance;
* Excellent elongation and abrasion resistance;
* Good dimensional stability;
* Good adhesion;
* Convenient construction.
Product Application
Used for railway tunnes, highway tunnels,subways,mining and all kinds of municipal underground engineerings.
