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.
