Composite Geomembrane 0.2mm+200GSM+0.2mm

Overview

Composite geomembranes are innovative geosynthetic composites that merge the superior barrier properties of geomembranes with the functional advantages of geotextiles. These materials are specifically engineered to deliver high - performance solutions for liquid and vapor containment, along with reinforcement and drainage functions. The composite structure typically consists of a geomembrane layer, which can be made from materials such as HDPE, PVC, or EPDM, laminated or coated with a geotextile fabric of varying thickness and strength. This strategic combination creates a versatile and multifunctional product that addresses multiple project requirements in a single material layer, offering significant advantages in terms of design simplification and project efficiency. Composite geomembranes have become a preferred choice for engineers and contractors seeking reliable and cost - effective solutions for complex geotechnical and environmental projects.

Features

Multifunctional Design: The integration of a geomembrane and geotextile into a single product provides a multifunctional solution that combines liquid and gas containment, mechanical reinforcement, and drainage in one material layer. This eliminates the need for separate layers of materials, reducing installation time and labor costs while simplifying the project design.

Superior Barrier Performance: The geomembrane component in composite geomembranes is specifically formulated to provide an excellent barrier against the passage of liquids and gases. Its molecular structure is designed to minimize permeability, ensuring that even in the presence of complex fluid mixtures or under varying pressure conditions, the barrier remains effective.

Reinforced Structural Integrity: The geotextile layer adds significant structural support to the composite geomembrane. It resists tension forces, prevents the geomembrane from stretching or deforming excessively, and distributes loads more uniformly across the material. This reinforcement is particularly valuable in applications where the composite geomembrane may be subjected to differential settlements, hydraulic loads, or mechanical stresses.

Drainage and Filtration Benefits: The geotextile layer also serves as a drainage and filtration medium. It allows for the controlled movement of fluids through the material while preventing the migration of fine soil particles. This helps to relieve excess pore water pressure behind the composite geomembrane, improving the overall stability of the engineered system and preventing potential failures due to hydraulic uplift or soil liquefaction.

Resistance to Microbial and Biological Degradation: Composite geomembranes are resistant to degradation from microorganisms and biological activities. This is crucial in applications where the material may be exposed to organic contaminants, biofilms, or other biological agents that could otherwise compromise the integrity of the barrier over time.

Custom - Designed Solutions: Composite geomembranes can be custom - designed to meet the specific needs of a project. This includes varying the thickness and formulation of the geomembrane layer to enhance specific barrier properties or adjusting the geotextile specifications to provide the required level of reinforcement and drainage. Custom widths and roll lengths are also available to optimize material usage and reduce waste during installation.

Applications

Liquid and Waste Containment: Composite geomembranes are widely used in the construction of landfill liners, industrial wastewater ponds, and sludge storage facilities. They provide a reliable barrier to prevent the leakage of harmful substances into the environment, ensuring the safe containment of liquids and wastes.

Mining and Mineral Processing: In mining applications, composite geomembranes are used to line tailings dams, heap leaching facilities, and mineral processing ponds. They contain potentially polluting mining fluids and help to manage the environmental impact of mining operations.

Water and Wastewater Infrastructure: They are applied in the construction of water storage reservoirs, wastewater treatment lagoons, and aeration basins. The composite geomembrane prevents water loss and contamination, supporting efficient water and wastewater management.

Construction and Building: Composite geomembranes serve as waterproofing membranes in building foundations, basements, and underground structures. They protect against water ingress and provide long - term waterproofing solutions for construction projects.

Environmental Restoration and Protection: These materials are used in the construction of caps and liners for contaminated sites, preventing the spread of pollutants and facilitating the restoration of affected areas. They are also used in the construction of wetlands and other ecological engineering projects to manage water flow and nutrient retention.
