Product Description
High-Performance Anti-Seepage Geotextiles for Tunnel Construction
Advanced tunnel waterproofing solution featuring innovative hanging system for simplified installation, improved efficiency, and reduced construction costs.
Product Overview
Hanging-type tunnel geotextile represents an innovative waterproof material that enables one-time nail construction pendant hanging. This system simplifies traditional tunnel waterproofing challenges, enhances laying efficiency and quality, shortens construction periods, and significantly reduces overall project costs.
Available Series
- Separate Waterproof Board: Geotextile and hanging belt geomembrane plate layered installation
- Compound Waterproof Board: Geotextile and geomembrane compounded via overall, point, or type methods with butt welds preserved, equipped with geotextile hanging belt for complete one-time installation
Key Properties
- Excellent anti-seepage performance and high barrier properties
- Superior puncture resistance and dimensional stability
