4000-6000g/m2
Yingfan
The 5.8m Bentonite Geosynthetic Clay Liner (GCL) is a high-performance waterproof material developed by Yingfan, adhering to ISO 9001 standards. Also known as sodium bentonite composite waterproof pad, this innovative liner integrates high-swelling sodium bentonite between specialized composite geotextile and non-woven fabric, bonded via needle punching technology. The unique structure creates numerous small fiber spaces that prevent one-way flow of bentonite particles. When hydrated, it forms a uniform, high-density colloidal waterproof layer, delivering exceptional impermeability for road construction and various waterproofing projects. With a basis weight range of 4000-6000g/m², it outperforms traditional compacted clay liners, making it a reliable choice for demanding waterproofing needs.
Property | National Standard (JG/T 193-2006) | Enterprise Standard | Inspection Standard |
Geosynthetic Clay Expansion Index | ≥24 ml/2g | ≥25 ml/2g | ASTM D5890 |
Mass Per Unit Area | ≥4800 g/m² | ≥4800 g/m² | ASTM D5993 |
Tensile Strength | ≥6 KN/m | ≥8 KN/m | ASTM 4632 |
Maximum Load Elongation | ≥10% | ≥10% | ASTM 4632 |
Permeability | ≤5×10⁻⁹ | ≤5×10⁻⁹ | ASTM D5084 |
Moisture Content | ≤15% | ≤15% | ASTM D4643 |
Peel Strength | ≥40 N | ≥65 N | ASTM 4632 |
Hydrostatic Pressure | 0.4 Mp | 0.4~0.6 Mp | ASTM D5891 |
Core Material: High-swelling sodium bentonite, selected for its superior water absorption and swelling capacity to form an impermeable barrier.
Composite Layers: Specialized composite geotextile and non-woven fabric, ensuring structural stability and durability.
Bonding Technology: Needle punching process, which interlocks fibers from the non-woven geotextile through the bentonite layer into the other geotextile (woven or non-woven), enhancing layer adhesion.
The bentonite geosynthetic clay liner forms a low-permeability clay layer upon hydration, with hydraulic protection equivalent to several feet of compacted clay, effectively preventing water leakage in road construction and other projects.
Unlike temporary waterproof solutions, this GCL offers long-lasting waterproofing, maintaining effectiveness even in harsh environmental conditions for road infrastructure.
With a simple construction process, the 5.8m width reduces splicing frequency, shortening the project timeline and lowering labor costs for road construction teams.
Not influenced by extreme temperatures, the liner performs reliably in both hot and cold climates, making it suitable for road projects in diverse regions.
Composed of natural bentonite and recyclable geotextiles, it is environmentally friendly, aligning with sustainable construction practices for modern road projects.
More versatile than traditional compacted clay, it adapts to irregular surfaces and complex project requirements, enhancing application flexibility in road construction.
The needle-punched structure increases airspace, improving liner efficiency and ensuring optimal waterproofing performance in road subgrade and foundation layers.
Ideal for waterproofing road subgrades, foundations, and drainage systems, preventing water damage to road structures and extending pavement lifespan.
Suitable for subway tunnels, underground garages, and roof waterproofing, providing reliable moisture protection for urban infrastructure.
Effective in landfills and industrial waste disposal sites, containing leachate and preventing environmental contamination.
Applied in rivers, lakes, dams, and reservoirs for waterproofing and reinforcement, safeguarding water conservancy facilities against leakage.
Perfect for artificial lakes, golf courses, and fish ponds, ensuring water retention and maintaining project integrity.
Used in oil depots, chemical yards, and petrochemical plants, offering corrosion-resistant waterproofing for hazardous material storage areas.
Compliant with ISO 9001 standards and national JG/T 193-2006 specifications, each batch of GCL waterproof material undergoes strict inspection to meet or exceed quality requirements.
Non-toxic and environmentally friendly, the liner poses no harm to human health or the ecosystem, making it safe for use in residential and public areas.
Manufactured with high-quality materials and advanced technology, the liner resists degradation, corrosion, and mechanical damage, ensuring long-term performance in road construction and other applications.
Ensure the construction surface is clean, flat, and free of sharp objects, debris, or standing water.
Store the liner in a dry, well-ventilated area to avoid moisture absorption before installation.
Unroll the 5.8m wide liner parallel to the road direction, minimizing wrinkles and tension.
Overlap adjacent liners by 15-20cm and secure with appropriate fasteners or adhesives to ensure a tight seal.
Use a roller to compact the liner, ensuring full contact with the substrate and eliminating air pockets.
Hydrate the liner evenly after installation to activate the bentonite’s swelling and waterproofing properties.
Regularly inspect the liner for damage, such as tears or punctures, especially after extreme weather or construction activities.
Repair any damage promptly using compatible patches and sealants to maintain waterproof integrity.
Avoid placing heavy machinery or sharp objects directly on the liner during maintenance or subsequent construction phases.
With proper installation and maintenance, the liner has a service life of over 50 years, providing long-term waterproofing for road construction and other projects.
Yes, the high-swelling sodium bentonite and corrosion-resistant geotextiles enable the liner to perform effectively in saline-alkali soil, resisting chemical degradation.
While the installation process is simple, professional installation is recommended to ensure proper overlapping, compaction, and hydration, maximizing waterproof performance.
The liner’s temperature resistance allows it to withstand freeze-thaw cycles without losing waterproofing ability, making it suitable for road projects in cold regions.
