GM13 0.5mm HDPE Geomembrane Dam Liner
1.Cost Efficiency Over Lifecycle
The GM13 0.5mm HDPE Geomembrane reduces replacement frequency by 30% compared to concrete or clay liners, saving 0.5–1/m² over 20 years. Its 50–100-year lifespan minimizes long-term maintenance costs, making it ideal for large-scale infrastructure projects.
2.Environmental Resilience
With UV resistance retaining >80% strength after 1,600 hours of exposure and puncture resistance of ≥300 N, the liner withstands extreme weather and mechanical stress. In landfills, it cuts methane emissions by 80%, aligning with global sustainability goals.
3.Versatility and Customization
Available in smooth or textured surfaces, the geomembrane adapts to flat (e.g., ponds) or sloped (e.g., dam faces) terrains. Customizable dimensions (widths up to 8m) and colors (black, white, blue) enable tailored solutions for diverse projects, from artificial lakes to biogas digesters.
Abstract
The GM13 0.5mm HDPE Geomembrane Dam Liner represents a cutting-edge solution for water containment challenges in dam construction, aquaculture, and environmental engineering. Manufactured from high-density polyethylene (HDPE) resin with added carbon black, antioxidants, and UV stabilizers, this geomembrane liner meets ASTM GRI-GM13 standards and offers superior durability, chemical resistance, and environmental adaptability. This article explores its technical specifications, applications, and competitive advantages, supported by empirical data and industry benchmarks.
Technical Specifications
The GM13 0.5mm HDPE Geomembrane Dam Liner is engineered to withstand harsh environmental conditions while maintaining structural integrity. Key parameters are summarized in Table 1:
Table 1: Core Technical Specifications
| Parameter | Value Range | Test Method |
Thickness | 0.5mm (±0.05mm) | ASTM D5199 |
Density | ≥0.940 g/cm³ | ASTM D1505 |
Tensile Strength (MD/TD) | ≥20 MPa (MD), ≥18 MPa (TD) | ASTM D638 |
Puncture Resistance | ≥300 N | ASTM D4833 |
UV Resistance (1600 hrs) | ≥80% strength retained | GRI GM13 |

This geomembrane is available in customizable widths (1–8m) and lengths (50–150m/roll), accommodating projects of varying scales. Its black color enhances UV absorption, while optional white or blue variants cater to aesthetic or thermal requirements.
Applications and Industry Adoption
The GM13 0.5mm HDPE Geomembrane is widely deployed across sectors requiring reliable water containment:
Dam Construction: Used as a primary liner to prevent seepage in earth dams, reducing water loss by up to 98% compared to unlined structures.
Aquaculture: Non-toxic liners improve water quality, boosting fish growth rates by 10% per FAO studies.
Environmental Engineering: Landfills and mining sites rely on its impermeability to block 99.9% of leachate migration, cutting groundwater contamination risks by 95%.

| Application | Key Benefit | Performance Data Source |
Dam Liners | 98% water retention efficiency | BPM Geosynthetics |
Aquaculture | 10% increased fish growth rate | FAO |
Landfills | 99.9% leachate containment | EPA Studies |
Key Challenges and Mitigation Strategies
Despite its strengths, the geomembrane’s performance hinges on proper installation. Warranty conditions require adherence to manufacturer-recommended procedures, such as ensuring a debris-free substrate and avoiding sharp edges. Additionally, while 0.5mm thickness suits moderate-pressure applications, high-stress zones (e.g., steep dam slopes) may necessitate thicker variants (0.75–1.5mm).
Conclusion
The GM13 0.5mm HDPE Geomembrane Dam Liner sets a benchmark for durability, cost efficiency, and environmental safety in water containment systems. 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.
