Product Overview

The Column-point Geomembrane is a high-performance geosynthetic material designed with raised column-like structures on its surface, which provide enhanced friction, facilitate drainage, and prevent slippage. This unique design is specifically engineered to improve soil retention and water flow in applications such as landfills, reservoirs, and construction sites. The Column-point Geomembrane combines excellent chemical resistance, UV stability, and high mechanical strength, making it a durable solution for demanding environmental and containment projects. It is particularly useful in applications where superior performance under stress, excellent drainage properties, and resistance to punctures and tears are critical.

Product Features

• Column-Like Surface Structure: The geomembrane features raised, column-like points that create a textured surface, improving friction and preventing slippage in soil and construction applications.
• Enhanced Drainage Performance: The unique surface structure facilitates the efficient drainage of water, helping to reduce water accumulation and improve the performance of drainage systems.
• High Tensile Strength: Designed to withstand mechanical stress, the geomembrane offers excellent tensile strength, ensuring its stability and longevity in challenging environments.
• UV and Weather Resistance: Made from high-density polyethylene (HDPE), the material is resistant to UV degradation, ensuring long-term performance even when exposed to sunlight.
• Chemical Resistance: The Column-point Geomembrane is highly resistant to a wide range of chemicals, making it suitable for applications in landfills, mining, and industrial sites where exposure to harsh chemicals is common.
• Durability: The robust construction ensures the geomembrane maintains its integrity over time, even under extreme pressure and in harsh environmental conditions.
• Versatility: Suitable for a wide range of applications, including waste containment, water storage, and infrastructure development.

• Agriculture: Suitable for agricultural ponds, irrigation systems, and farm-based containment applications to prevent water loss and contamination.
• Infrastructure Projects: Ideal for use in roads, tunnels, and other infrastructure projects where water drainage and soil stabilization are critical.

Construction Recommendations

1. Site Preparation: Ensure that the installation site is free from sharp objects, rocks, or any debris that may damage the Column-point Geomembrane. The surface should be smooth and compacted to provide a stable foundation for the membrane.

2. Installation Method: Unroll the geomembrane carefully, avoiding any sharp bends or creases that could weaken the material. The rolls should be laid out with minimal tension, and the column-like structures should face upwards to ensure effective drainage and friction.

3. Seam Welding: The seams of the Column-point Geomembrane should be welded using extrusion or wedge welding techniques. Proper welding is crucial to ensure a strong, leak-proof bond between adjacent sheets. Verify seam quality with tests such as air or vacuum testing.

4. Protection During Installation: Protect the geomembrane from punctures during installation by using a protective layer, such as sand or geotextile fabric, to prevent damage from equipment or sharp objects.

5. Backfilling and Covering: Once the geomembrane is in place, cover it with a protective layer, such as soil or gravel, to shield it from UV exposure, physical damage, and environmental stress. The backfill should be compacted gently to avoid applying excessive pressure on the membrane.

6. Inspection and Maintenance: Regularly inspect the geomembrane for signs of wear, punctures, or deformation. In case of damage, promptly repair the affected area using appropriate welding or patching methods. Regular monitoring is particularly important in high-load or high-water environments.
