Product Overview

The Reservoir Geomembrane is an advanced waterproofing solution designed to line reservoirs and provide effective containment of water, chemicals, and other liquids. Made from high-density polyethylene (HDPE) or PVC, this geomembrane offers exceptional durability and impermeability, ensuring that water is securely contained and does not leak into the surrounding environment. Reservoirs are often exposed to extreme weather conditions, chemicals, and mechanical stress, and the Reservoir Geomembrane is specifically engineered to withstand these challenges. Whether for agricultural, industrial, or municipal use, the Reservoir Geomembrane ensures reliable performance and environmental protection.

Product Features

• Waterproofing & Leak Prevention: The primary function of the Reservoir Geomembrane is to prevent water leakage, providing a reliable barrier that keeps water contained and prevents soil and groundwater contamination.
• Chemical Resistance: The geomembrane is highly resistant to a wide range of chemicals, including salts, acids, and other substances commonly found in water sources and industrial applications.
• UV Resistance: It is treated with UV stabilizers, making it suitable for prolonged outdoor exposure without degradation from sunlight.
• Durability: The Reservoir Geomembrane is designed for long-term use and can withstand harsh environmental conditions, including extreme temperatures and mechanical stress.
• Low Permeability: The material offers extremely low permeability (less than 1 x 10^-13 cm/s), ensuring that water or other fluids do not pass through the membrane.
• Environmental Protection: By effectively containing water and preventing leakage, it protects the surrounding environment from contamination and preserves the quality of nearby soil and groundwater.
• Ease of Installation: With its flexibility and smooth surface, the Reservoir Geomembrane can be easily installed, reducing the time and labor costs associated with installation.

Product Specifications

• Material: The geomembrane is typically made from HDPE (High-Density Polyethylene) for excellent mechanical strength and chemical resistance. PVC or other materials may also be used depending on project requirements.
• Thickness: Standard thicknesses typically range from 0.5 mm to 3.0 mm, depending on the specific application and environmental conditions.
• Width: The standard roll width is usually between 4 meters to 6 meters, but custom widths are available depending on the size of the reservoir.
• Length: Rolls typically come in lengths from 50 meters to 100 meters, with longer lengths available upon request.
• Tensile Strength: The geomembrane typically has a tensile strength ranging from 15 to 35 MPa, making it resistant to external stress and pressure.
• Elongation at Break: Typically ranges from 10% to 15%, allowing the geomembrane to stretch and adapt to movement without breaking or cracking.
• Permeability: Very low permeability, generally less than 1 x 10^-13 cm/s, ensuring excellent water containment.
• Color: Generally black to increase UV resistance and minimize algae growth. Custom colors may be available based on specific needs.

Applications

• Agricultural Water Storage: Used for lining reservoirs that store irrigation water, helping to reduce water loss through seepage and ensuring that water is available for agricultural use.
• Industrial Applications: Applied in industrial settings where large volumes of water, chemicals, or waste products need to be contained, such as cooling ponds or wastewater treatment facilities.
• Municipal Water Supply: Suitable for municipal water reservoirs, providing reliable waterproofing and reducing the risk of contamination from external sources.
• Rainwater Harvesting Systems: Used to line storage tanks for rainwater collection, ensuring that the stored water remains clean and uncontaminated.
• Stormwater Management: Applied in stormwater retention basins to prevent water leakage and to manage runoff in urban areas.
• Mining Operations: Used in mining facilities to store process water, tailings ponds, and other fluid containment applications where water must be prevented from leaking into the environment.

Construction Recommendations

1. Site Preparation: Before installation, ensure that the site is properly prepared by removing sharp objects, rocks, and debris that could damage the geomembrane. The surface should be smooth, compacted, and free of large debris to prevent punctures during installation.

2. Installation Method: Roll out the Reservoir Geomembrane gently to avoid damage. Ensure the membrane is laid flat and that any wrinkles or creases are removed to prevent tension on the material. Adjacent sheets should be overlapped or welded to form a continuous and watertight seal.

3. Seam Welding: Use extrusion welding or hot wedge welding to join adjacent sheets. The seams must be thoroughly tested, such as through air or vacuum testing, to ensure they are watertight and structurally sound.

4. Protection During Installation: Use geotextile fabrics or other protective materials to shield the geomembrane from sharp rocks, construction equipment, or other risks that may puncture or tear the material during installation.

5. Backfilling and Covering: After installation, cover the geomembrane with a protective layer, such as soil or gravel, to prevent UV degradation and mechanical damage. Backfilling should be done carefully and evenly to avoid overloading or stressing the geomembrane.

6. Inspection and Maintenance: Regular inspections should be performed to check for any punctures, tears, or damage to the geomembrane. If any issues are found, immediate repairs using welding or patching should be done. Routine maintenance will ensure the geomembrane continues to perform effectively over time.
