Product Overview

The 3D Drainage Geonet is an advanced geosynthetic drainage material designed to efficiently collect and redirect water in a wide range of applications, such as landfills, roads, and building foundations. Composed of a three-dimensional network of polymeric fibers, it provides excellent drainage capacity, filtration, and separation. Its unique structure helps to prevent soil erosion, manage water flow, and reduce the risk of flooding or damage from leachate or excess water. The 3D Drainage Geonet is highly durable, resistant to chemical degradation, and performs well under heavy loads, making it ideal for long-term drainage systems in harsh conditions.

Product Features

• High Drainage Efficiency: The three-dimensional design of the geonet allows for enhanced water flow and drainage, ensuring efficient management of water and leachate in landfill and other containment systems.
• Compressive Strength: It can withstand significant compressive forces, maintaining its drainage capacity even under heavy soil or structural loads.
• Durability: Made from UV-resistant and chemically stable materials, the geonet is designed to perform under extreme environmental conditions without degrading.
• Prevention of Clogging: The unique 3D structure prevents clogging by allowing free flow of water while filtering out particles and debris, which is essential for maintaining drainage effectiveness.
• Easy Installation: The geonet is lightweight and easy to handle, making it suitable for quick and cost-effective installation in large-scale drainage projects.
• Environmental Protection: It helps to contain and direct water flow, preventing the contamination of surrounding soil and groundwater, and protecting ecosystems.

Product Specifications

• Material Composition: Typically made from high-density polyethylene (HDPE) or polypropylene fibers, forming a 3D drainage network.
• Thickness: The standard thickness is between 5 mm and 15 mm, depending on the required drainage capacity and application.
• Width: Available in rolls ranging from 1 meter to 6 meters wide, ideal for large-scale applications such as landfills, roads, and building foundations.
• Length: Rolls are usually available in lengths of 50 to 100 meters, offering flexibility in project size and coverage.
• Drainage Capacity: The geonet provides a drainage rate of up to 5 liters per second per meter width, depending on the installation angle and soil conditions.
• Tensile Strength: Typically ranges from 15-30 kN/m, ensuring the material's stability under mechanical stress.
• UV Resistance: The geonet is UV stabilized and resistant to degradation from prolonged sunlight exposure, with a typical UV resistance rating of 80% over 5000 hours.

Applications

• Landfills: Used as a drainage layer to manage leachate and groundwater in landfills, preventing water buildup and ensuring stable conditions for waste containment.
• Road Construction: Ideal for managing drainage in road construction, particularly for subgrade drainage and managing stormwater runoff.
• Building Foundations: Used in the construction of foundations to prevent water accumulation and ensure proper drainage beneath buildings, protecting structures from moisture damage.
• Retaining Walls: Can be used behind retaining walls to allow water to flow freely, reducing hydrostatic pressure and preventing wall failure.
• Agriculture: Effective in managing water flow in agricultural drainage systems, helping to protect crops from waterlogging and improve soil aeration.
• Environmental Protection: Applied in environmental remediation projects to control water movement and prevent contamination of surrounding soil and groundwater.

Construction Recommendations

1. Site Preparation: Ensure the installation site is clean, smooth, and free of debris that could damage the geonet. The subgrade should be compacted and stable to support the geonet without causing deformation.

2. Installation Method: Unroll the 3D Drainage Geonet along the designated drainage path, making sure it is aligned with the direction of water flow. Minimize overlap between rolls to avoid disrupting the continuous drainage network. Overlap should be at least 30 cm at the seams to ensure proper functionality.

3. Seam and Joint Sealing: Properly connect adjacent rolls to ensure a seamless drainage system. Depending on the application, mechanical stitching or adhesive bonding may be used for securing seams and preventing water leaks.

4. Protection During Installation: Avoid direct exposure to UV rays for prolonged periods before the geonet is covered. Use appropriate equipment to handle the material carefully to prevent punctures or damage during installation.

5. Backfilling and Covering: Once the geonet is installed, cover it with a layer of soil, gravel, or other protective material to prevent UV degradation, physical damage, or movement of the material.

6. Quality Control: Inspect the geonet after installation to ensure that there are no gaps or damage that could affect drainage performance. Perform periodic checks to ensure continued functionality, especially in areas exposed to heavy water flow or mechanical stress.
