The Composite Geomembrane is a high-performance, multi-layered
geosynthetic material designed for superior containment, barrier
protection, and environmental safety. Combining the strength of
geotextiles with the impermeability of geomembranes, this product
offers unmatched durability, flexibility, and resistance to
environmental stressors. It is widely used in applications such as
landfill liners, pond and reservoir liners, mining operations, and
environmental protection projects.
Key Features:
Exceptional Impermeability:
The geomembrane layer provides an impermeable barrier, effectively
preventing the leakage of liquids, gases, and contaminants. This
makes it ideal for applications requiring strict containment, such
as hazardous waste storage and water conservation.
High Tensile Strength:
Reinforced with geotextile layers, the composite geomembrane
exhibits excellent tensile strength and puncture resistance,
ensuring long-term performance even under heavy loads and harsh
conditions.
UV and Chemical Resistance:
Manufactured from high-quality polymers, the geomembrane is
resistant to UV radiation, chemical degradation, and biological
attack, making it suitable for both exposed and buried
applications.
Flexibility and Adaptability:
The composite geomembrane is highly flexible, allowing it to
conform to irregular surfaces and accommodate ground movements
without compromising its integrity.
Easy Installation:
Lightweight and available in large rolls, the composite geomembrane
is easy to transport, handle, and install, reducing labor costs and
project timelines.
Environmental Protection:
By preventing the migration of pollutants and conserving water
resources, the composite geomembrane contributes to sustainable
development and environmental protection.
Applications:
Landfill Liners and Caps: Provides a reliable barrier to prevent leachate contamination of
soil and groundwater.
Pond and Reservoir Liners: Ensures water retention and prevents seepage in agricultural,
industrial, and recreational water storage systems.
Mining Operations: Used in heap leach pads, tailings dams, and containment ponds to
manage process fluids and prevent environmental contamination.
Wastewater Treatment: Lines lagoons and tanks to contain and treat wastewater
effectively.
Aquaculture: Creates durable and safe containment systems for fish and shrimp
farming.
Environmental Remediation: Isolates contaminated sites to prevent the spread of pollutants.
Specifications:
Material: High-Density Polyethylene (HDPE), Linear Low-Density Polyethylene
(LLDPE), or Polyvinyl Chloride (PVC) geomembrane laminated with
non-woven geotextile.
Thickness: Available in various thicknesses (e.g., 0.5mm to 3.0mm).
Width: Standard rolls of 2m to 8m wide, customizable to project
requirements.
Tensile Strength: High tensile strength to withstand mechanical stress.
Puncture Resistance: Excellent resistance to punctures and tears.
Temperature Range: Performs reliably in a wide temperature range, from -50°C to 80°C.

Installation Guidelines:
Surface Preparation:
Ensure the subgrade is smooth, compacted, and free of sharp objects
or debris that could damage the geomembrane.
Unrolling and Positioning:
Unroll the composite geomembrane and position it carefully,
ensuring proper alignment and minimal wrinkles.
Seaming and Welding:
Overlap adjacent sheets and use thermal fusion welding, extrusion
welding, or adhesive bonding to create strong, leak-proof seams.
Anchoring and Protection:
Secure the edges of the geomembrane with anchor trenches or
mechanical fasteners. Cover the geomembrane with a protective layer
(e.g., soil or geotextile) to prevent UV exposure and mechanical
damage.
