Product Overview

The 3D Composite Drainage Net is an advanced geosynthetic material designed to facilitate efficient drainage, prevent water accumulation, and provide soil separation in a wide range of civil engineering applications. Made from a combination of synthetic fibers and geonet layers, this product features a unique three-dimensional structure that provides high drainage capacity and excellent filtration properties. It is primarily used for managing water flow in landfill sites, construction foundations, roads, and retaining walls. The geonet's composite structure ensures long-term performance, resistance to physical and chemical stress, and protection against environmental degradation.

Product Features

• Enhanced Drainage Performance: The three-dimensional structure provides excellent drainage rates, making it ideal for managing large volumes of water, preventing water accumulation, and improving water flow in landfills and other drainage systems.
• High Compressive Strength: Designed to withstand heavy loads and pressure, the composite drainage net maintains its functionality even under extreme conditions, such as in landfill sites or construction zones.
• UV and Chemical Resistance: Made from durable materials like high-density polyethylene (HDPE), it resists UV degradation and exposure to chemicals, ensuring a long service life in outdoor environments.
• Effective Soil Separation and Filtration: The product effectively separates soil layers and filters out fine particles, ensuring that drainage systems remain free of clogging and sediment buildup.
• Lightweight and Easy to Install: The material is lightweight and easy to handle, making installation quick and cost-effective, even for large-scale projects.
• Environmental Protection: It plays a crucial role in protecting the environment by directing water flow, preventing groundwater contamination, and ensuring the efficient management of leachate in landfills.

Product Specifications

• Material Composition: Typically made from high-density polyethylene (HDPE) or polypropylene fibers, combined with a geonet layer to form a composite structure.
• Thickness: Ranges from 5 mm to 15 mm, depending on the specific application requirements and drainage capacity needed.
• Width: Available in rolls with widths ranging from 1 meter to 6 meters, making it versatile for various installation sizes.
• Length: Standard roll lengths are typically 50 meters to 100 meters, depending on the specific application and project size.
• Drainage Capacity: Offers a drainage rate of up to 5 liters per second per meter width, depending on soil and installation conditions.
• Tensile Strength: Tensile strength ranges from 15-30 kN/m, providing durability under mechanical stress.
• UV Resistance: UV resistance is generally rated up to 80% after 5000 hours of exposure, ensuring long-term durability under sunlight.

Applications

• Landfills: Used as a drainage layer to manage leachate and groundwater, preventing water accumulation and ensuring stable waste containment conditions.
• Road Construction: Ideal for subgrade drainage, helping to prevent water damage to roads, improving stability, and increasing the longevity of road foundations.
• Building Foundations: Helps direct water away from building foundations, preventing moisture buildup and protecting structures from water damage and mold.
• Retaining Walls: Applied behind retaining walls to reduce hydrostatic pressure and allow water to flow freely, preventing wall failure and erosion.
• Agricultural Drainage: Used in agricultural applications to manage excess water and ensure proper soil aeration, preventing waterlogging and improving crop yield.
• Stormwater Management: Provides an efficient solution for stormwater drainage in construction and urban areas, reducing the risk of flooding and soil erosion.
• Environmental Protection: Plays a key role in protecting ecosystems by efficiently managing water flow and preventing soil or groundwater contamination.

Construction Recommendations

1. Site Preparation: Ensure that the installation area is clean, smooth, and free from sharp objects or debris that could damage the 3D Composite Drainage Net. The ground should be compacted to provide a stable base for the material.

2. Installation Method: Unroll the geonet along the designated drainage path, ensuring it is properly aligned with the direction of water flow. The rolls should be laid out without excessive tension to prevent distortion or movement during installation.

3. Seam and Joint Sealing: Overlap adjacent rolls by at least 30 cm to ensure proper coverage and prevent water leakage. Depending on the project, seams can be joined using mechanical methods or adhesive bonding to ensure continuous drainage.

4. Protection During Installation: While installing, avoid direct exposure of the geonet to UV rays for prolonged periods. Ensure the material is protected from mechanical damage during handling and installation.

5. Backfilling and Covering: Once the 3D Composite Drainage Net is in place, it should be covered with soil, gravel, or another protective layer to prevent damage from UV radiation and physical stress. The backfill should be compacted to stabilize the geonet and maintain its functionality.

6. Quality Control: After installation, check for any gaps, overlaps, or damage that could affect the drainage system’s performance. Regular monitoring should be conducted, particularly in areas where high water flow is expected.
