GM13 0.75mm HDPE Geomembrane Dam Liner
1.Superior Environmental Resilience
The GM13 0.75mm HDPE Geomembrane withstands UV exposure, chemical corrosion, and temperature extremes (-50°C to +80°C) without degrading. In landfill applications, it blocks 99.9% of leachate migration, reducing groundwater contamination risks by 95% (EPA, 2023). Its carbon-black additive enhances UV absorption, extending lifespan by 30% compared to non-stabilized alternatives.
2.Cost Efficiency Over Lifecycle
With a 50–100-year service life, the 0.75mm variant reduces replacement costs by 40% versus 0.5mm liners in high-stress zones (e.g., dam slopes). Its puncture resistance of ≥93 N minimizes repair incidents, which average 200–500 per event. For a 10,000m² dam project, this translates to $120,000 in savings over 20 years.
3.Versatility and Customization
Available in widths up to 8m and lengths of 50–100m/roll, the geomembrane adapts to projects of any scale. Smooth or textured surfaces cater to specific needs: smooth liners reduce friction in water ponds, while textured variants enhance slope stability in dam applications. Custom colors (black, white, blue) and UV-resistant coatings further tailor solutions to environmental or aesthetic requirements.
Abstract
The GM13 0.75mm HDPE Geomembrane Dam Liner represents a critical advancement in water containment technology, combining high-density polyethylene (HDPE) material with ASTM GRI-GM13 standard compliance to deliver unmatched durability, environmental adaptability, and cost efficiency. Designed for dam liners, aquaculture ponds, landfills, and industrial reservoirs, this geomembrane addresses global demands for sustainable infrastructure with a 50–100-year service life. This article examines its technical specifications, performance metrics, and competitive advantages, supported by empirical data and industry benchmarks.
Technical Specifications and Performance Metrics
The GM13 0.75mm HDPE Geomembrane is engineered to meet stringent international standards, including ASTM D7176 and GRI-GM13, ensuring reliability in extreme conditions. Key parameters are summarized in Table 1:
Table 1: Core Technical Specifications
| Parameter | Value Range | Test Method |
Thickness | 0.75mm (±0.075mm) | ASTM D5199 |
Density | ≥0.940 g/cm³ | ASTM D1505 |
Tensile Strength (MD/TD) | ≥20 kN/m (MD), ≥18 kN/m (TD) | ASTM D6693 Type IV |
Puncture Resistance | ≥93 N | ASTM D1004 |
UV Resistance (1600 hrs) | ≥80% strength retained | GRI GM13 |
Service Life | 50–100 years | ISO 9001:2015 |
The geomembrane’s 0.75mm thickness balances flexibility and strength, making it suitable for both flat surfaces (e.g., reservoirs) and sloped terrains (e.g., dam faces). Its blowing-extrusion manufacturing process ensures uniform thickness distribution, minimizing weak points. Table 2 compares performance across thickness variants to highlight 0.75mm’s optimal cost-benefit ratio:

Applications and Industry Adoption
The GM13 0.75mm HDPE Geomembrane is deployed across sectors requiring reliable water containment:
Dam Construction: Used as a primary liner in earth dams, it reduces seepage by 98%, preserving water resources in arid regions.
Aquaculture: Non-toxic, FDA-compliant liners improve water quality, boosting fish growth rates by 10% (FAO, 2024).
Landfills: Certified by ISO 9001 and CE, it meets global environmental standards for hazardous waste containment.
Key Challenges and Mitigation Strategies
While robust, the geomembrane’s performance hinges on proper installation:
Cold Weather: Below 5°C, seam strength drops by 20%. Solution: Preheat substrates and use hot-air welding tools.
Complex Terrains: Irregular surfaces increase labor by 15%. Solution: Employ 3D modeling to pre-cut panels for precise fitting.
Puncture Risks: Requires ELLS (Electrical Leak Location Survey) for detection (500–1,000 per survey). Solution: Use geotextile underlays to distribute stress.
Conclusion
The GM13 0.75mm HDPE Geomembrane Dam Liner sets a benchmark for durability, cost efficiency, and environmental safety in water management infrastructure. Its adherence to ASTM GRI-GM13 standards, coupled with customizable features, positions it as a preferred choice for engineers and contractors worldwide. By addressing both immediate operational needs and long-term sustainability, this geomembrane liner exemplifies innovation in geosynthetic technology, driving progress in dam construction, aquaculture, and environmental engineering.
