Water Conservancy Composited Geotextile Membrane Two Layer Anti Seepage Reinforcement

About Composited Geotextile Membrane

Composite geomembrane is made of geotextile (base fabric can be filament or short fiber needle punched geotextile ,woven geotextile )and high polymer by calendering and hot-melt technology .It remains the mechanical properties of base fabric and uniformity of film which improve the impermeability .Embossed processing on the film strengthen its friction coefficient,stability and easy for installation .

Application scenarios of composited geotextile membrane

Composite geomembrane is a multi-layer composite material that combines anti-seepage and reinforcement functions. Its application scenarios are wide and diverse, mainly covering the following areas:

Environmental protection and sanitation engineering

1. Landfill: Used as bottom anti-seepage layer and cover layer to prevent harmful substances from penetrating into soil and groundwater and prevent secondary pollution.
2. Sewage treatment pool: As an anti-seepage isolation layer, it prevents sewage leakage from polluting the surrounding environment and is suitable for industrial wastewater treatment such as chemical industry and electroplating.

​Water Conservancy and Hydropower Engineering

1. Reservoirs and dams: Used for anti-seepage reinforcement of dam bodies, such as the core anti-seepage layer in the South-to-North Water Diversion Project to reduce the risk of leakage.
2. Channels and artificial lakes: Layed on the inner wall of the channel or the bottom of the artificial lake to prevent water loss and improve water storage efficiency.
3. Hydropower stations and cofferdams: Reinforce the dam foundation, drain groundwater, reduce seepage pressure, and ensure structural stability.

​Agriculture and breeding

1. Fish ponds and reservoirs: As lining materials, it is corrosion-resistant and UV-resistant, reduces water leakage and prolongs service life.

2. Irrigation system: Used for orchard drainage, pond dam covering, and optimizes water resource utilization efficiency.

Technical advantages

1. Performance improvement

• High strength: Geotextile has enhanced tensile and tear resistance, and is suitable for high stress environments.
• Durability: HDPE geomembrane is acid and alkali resistant, anti-aging, and has a service life of more than 50 years.
• Easy construction: Can be hot-melt welded, with high seam strength, reducing the risk of leakage.

2. Environmental protection and economy

Reduce the pollution of traditional anti-seepage materials (such as asphalt), and the composite structure reduces the amount of materials used.

Technical standards and tests

     1. Key standards

ASTM D6636: Test the interlayer peel strength of composite geomembranes to ensure the bonding quality.

GB/T 17642: Standardize parameters such as geomembrane thickness and puncture resistance.

2. Quality control

Use scanning electron microscopy (SEM) and atomic force microscopy (AFM) to detect the microstructure of the membrane surface and optimize the anti-seepage performance.

Purchase Recommendations

Parameter Selection

Thickness: Choose 0.2-3mm according to project requirements, and 1.5mm or more is recommended for high corrosion environments.

Material: HDPE is suitable for long-term exposure scenarios, and EVA is suitable for short-term or low-temperature environments.
