3. Key Advantages

(1) Superior Impermeability

The 0.5mm HDPE core, flanked by geotextile layers, creates an ultra - tight seal. With a permeation coefficient ≤1×10⁻¹³ cm/s, it effectively blocks liquid and gas penetration, making it ideal for applications like landfills, reservoirs, and wastewater treatment ponds.

(2) Enhanced Strength & Durability

The composite structure combines the tensile strength of geotextiles and the rigidity of HDPE. It resists punctures, tears, and deformation under heavy loads, ensuring long - term performance even in harsh environments.

(3) Excellent Chemical & Weather Resistance

The HDPE core offers strong resistance to acids, alkalis, and organic solvents. Additionally, it withstands UV exposure, extreme temperatures, and weathering, ensuring durability over time.

(4) Cost - Effective & Installation - Friendly

Lightweight yet robust, this geomembrane simplifies handling and installation. Its compatibility with hot - air welding technology enables seamless connections, reducing installation time and labor costs. The long lifespan and low maintenance requirements further contribute to overall cost savings.

4. Applications

(1) Environmental Protection:

In landfills, the 200g/0.5mm/200g Composite Geomembrane acts as a crucial barrier, preventing leachate from seeping into the soil and groundwater. For instance, in large - scale landfill projects, it helps contain harmful substances, protecting the surrounding ecosystem.
During contaminated soil remediation, it can be used to isolate polluted areas, stopping the spread of contaminants and facilitating effective treatment.

(2) Water Engineering:

In reservoir construction, the geomembrane provides reliable waterproofing, ensuring water storage integrity. It also reduces water seepage losses, optimizing water resource utilization.
For fish ponds, it helps maintain water quality by preventing the intrusion of soil particles and contaminants, creating a healthy breeding environment for aquatic life.

(3) Construction:

In basement waterproofing, the composite geomembrane effectively blocks moisture, protecting building structures from water damage. It has been successfully applied in many high - rise buildings and underground facilities.
For tunnel lining, it offers both waterproofing and structural support, enhancing the durability and safety of the tunnel. Additionally, in the construction of artificial lakes for urban landscaping, it helps create beautiful water features while ensuring long - term water retention.
