Enhanced Protection - Dual geotextile layers safeguard the central geomembrane from punctures.
Bidirectional Filtration - Allows for drainage/filtration on both surfaces of the composite.
Stress Distribution - Evenly distributes loads to protect the impermeable core layer.
Installation Durability - Withstands construction stresses from both sides during placement.
Comprehensive Barrier System - Provides complete protection, filtration and containment in one product.
Product Introduction:
The composite geosynthetic material, known as "Two Fabric, One Membrane," is engineered by bonding geotextiles (including needle-punched, woven, or plastic-based fabrics) with polymer films (such as HDPE, LDPE, or EVA) through advanced thermal fusion and calendering techniques. This integration results in a high-performance solution tailored for diverse civil and environmental engineering applications.
Technical Specifications:
Width Range: 2–7 meters
Unit Weight: 300–2600 grams per square meter
Product Applications:
1. Hydraulic Engineering: Reinforcement and seepage prevention in river levees, reservoir dams, tailing ponds, irrigation canals, and liquid containment structures.
2. Underground Construction: Waterproofing for subway systems, basements, underground tunnels, and tunnel linings.
3. Transport Infrastructure: Anti-salt seepage barriers for roadbeds and foundational layers.
4. Coastal & Geotechnical Works: Horizontal and vertical seepage control in embankments, cofferdams, and landfill sites.
5. Aquaculture: Lining for freshwater and marine breeding ponds.
6. Road & Rail Networks: Moisture barriers in highways, railways, and expansive soil stabilization.
Product Features:
1. Enhanced Grip: The fabric-film composite increases surface friction, enabling stable placement on steep slopes and optimizing land use.
2. Robust Performance: Superior resistance to stretching, tearing, bursting, and puncturing under stress.
3. Adaptability: Efficiently redistributes strain caused by uneven substrates, maintaining structural integrity.
4. Pressure Relief: Facilitates rapid dissipation of interstitial water pressure and buoyant forces.
5. Thermal Protection: Mitigates frost-heave damage to membranes, preserving soil stability.
6. Longevity: Underground installation extends service life with minimal degradation, lowering upkeep demands.
7. Cost Efficiency: Lightweight design simplifies transport, accelerates deployment, and cuts overall project expenses.
