Product Description
Drainage Geocomposite for Efficient Water Drainage and Containment
Drainage geocomposite is a three-layer composite material consisting of a geonet core sandwiched between two geotextile layers, providing both drainage and filtration functions. This innovative product combines the drainage capacity of a geonet with the filtration and separation properties of geotextiles, creating an efficient drainage system for various civil engineering applications.
Haoyang Environmental offers high-quality drainage geocomposites that provide excellent in-plane drainage capacity, filtration performance, and mechanical strength. Our products are engineered to handle high flow rates while preventing soil particle migration, ensuring long-term performance in demanding environments.

Project Cases
1. Landfill Drainage
Drainage geocomposite provides efficient leachate collection and gas venting in landfill applications, reducing hydrostatic pressure and improving landfill stability.
2. Retaining Wall Drainage
Used behind retaining walls to collect and drain groundwater, reducing hydrostatic pressure and preventing wall failure.
3. Tunnel Drainage
Applied in tunnel construction to collect and drain groundwater, protecting the tunnel lining from water pressure and preventing water ingress.
4. Roof Drainage
Used in green roofs and roof gardens to provide drainage and water retention, reducing roof loads and improving thermal insulation.
5. Road and Railway Drainage
Installed beneath road and railway embankments to provide drainage and prevent water accumulation, reducing frost heave and improving subgrade stability.
FAQ
Q1: Are you a factory or a trading company?
A1: We are a professional manufacturer of geomembrane, geotextile, composite geomembrane, etc., with ISO9001 quality management system certification.
Q2: Could you please send the sample before confirming the order?
A2: Yes, we’d be happy to send you a free sample for evaluation if you’d like.
Q3: Can you produce according to the customer’s requirements?
A3: Of course. We are professional manufacturers. OEM and ODM are welcome.
Q4: How do you guarantee the quality testing of your products?
A4: The testing center of Haoyang Environmental Co., Ltd. obtained the CNAS Laboratory accreditation Certificate, certificate number L11088. Each batch of products will undergo rigorous testing before leaving the factory.
Q5: What is the main material of this drainage geocomposite?
A5: Our drainage geocomposites are made from high-density polyethylene (HDPE) geonet core and polypropylene (PP) geotextile layers, which provide excellent drainage capacity and filtration performance.
Q6: What are the advantages of drainage geocomposite?
A6: Drainage geocomposite offers high in-plane drainage capacity, excellent filtration properties, easy installation, and reduced construction thickness compared to traditional granular drainage layers.
Q7: What is the difference between drainage geocomposite and geotextile?
A7: Drainage geocomposite provides both drainage and filtration functions, while geotextile primarily provides filtration and separation. Geocomposite has a geonet core that creates drainage channels for water flow.
Q8: How is the drainage geocomposite installed?
A8: Installation involves surface preparation, unrolling and positioning, overlapping and seaming, and covering with protective layers. The geotextile side should face the soil to provide filtration.
