Composite geomembrane liner is a water impermeable material composed of geotextile and geomembrane. The composite geomembrane liner has the functions and advantages of both geotextiles and geomembranes. The geotextile layer increases essential tensile strength and the geomembrane layer provides excellent impermeable, leak and moisture proof. Composite geomembrane is mainly used for anti-seepage civil engineering applications. Its anti-seepage performance mainly depends on the anti-seepage performance of the geomembrane.
What Is Composite Geomembrane Liner?
Composite geomembrane liner has high physical and mechanical performance indicators such as tensile strength, tear resistance, bursting, etc. The composite geomembrane liner has the characteristics of high strength, good elongation performance, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good permeability resistance, etc. It can meet the needs of civil engineering in water conservancy, municipal administration, construction, transportation, subway, tunnel, engineering construction, seepage prevention, isolation, reinforcement, crack prevention and reinforcement. Because it uses HDPE material and anti-aging agent is added in the production process, it can be used in unconventional temperature environment. The composite geomembrane liner is commonly used for anti-seepage treatment of dams and drainage ditches, and anti-fouling treatment of waste yards.

4) Multi-layers composite geomembrane, weight of base geotextile is 100gsm – 1000gsm, thickness of geomembrane is 0.1mm-1.5mm.
Case Study Of Composite Geomembrane Liner
In 2019, BPM team received an inquiry from a Thai customer about composite geomembrane. After communication, BPM learned that the Thai customer company is committed to waterproofing engineering and has experience in related reservoir project. The customer found several composite geomembrane suppliers. After conducting various inspections, the customer decided Sample testing, collected samples from various companies, and tested at professional institutions. The BPM composite geomembrane passed the test smoothly. The indicators met customer requirements. Thai customers highly recognized the quality, product and supply capabilities, strength and credibility of BPM composite geomembrane. Because BPM has been committed to the research and development, production, sales and service of geosynthetics since its establishment, and has 10 years of experience. The client finally decided to choose the BPM team and wanted to maintain long-term cooperation with us.
Specifications of Composite Geomembrane Liner for Reservoir Project in Thailand
- Total Composite Geomembrane Quantity – 70,000 square meters
- Composite Geomembrane specification – 600 gsm
- Each roll size is 6m*100m
How to Choose the Right Composite Geomembrane Liner
When selecting a composite geomembrane liner for your project, several factors must be considered to ensure optimal performance and longevity. Composite geomembranes are widely used in environmental, mining, water containment, and industrial applications due to their excellent barrier properties and durability. Here’s a guide to help you make the right choice, with a mention of BPM Geomembrane as a reliable option.
Key Factors to Consider
1. Material Type
Composite geomembranes typically consist of a geomembrane layer (such as HDPE, LDPE, or LLDPE) bonded to a geotextile or another protective layer. The choice depends on:
-
Chemical Resistance: HDPE offers high chemical resistance, making it ideal for landfills and hazardous waste containment.
-
Flexibility: LLDPE and LDPE are more flexible, suitable for uneven surfaces.
-
Puncture Resistance: A geotextile-backed composite enhances protection against punctures.
2. Thickness and Strength
The thickness of the geomembrane affects its durability and puncture resistance. Thicker liners (e.g., 1.5mm to 2.0mm) are better for heavy-duty applications like mining or landfill caps.
3. UV Resistance
If the liner will be exposed to sunlight, ensure it has UV stabilization to prevent degradation over time.
4. Seaming and Installation
Proper installation is critical. Some composite geomembranes are easier to weld (like HDPE), while others may require specialized seaming techniques.
5. Permeability Requirements
For applications requiring low permeability (e.g., potable water storage), a high-quality geomembrane with minimal permeability is essential.
6. Regulatory Compliance
Ensure the liner meets industry standards such as GRI-GM13, ASTM, or other local regulations.
