Get to Know Geosynthetic Geonet
A geosynthetic geonet is a drainage layer made from high-density polyethylene (HDPE) or polypropylene, extruded into a three-dimensional mesh structure.
It allows liquids and gases to flow freely between soil and geomembrane layers, preventing water buildup and maintaining slope or foundation stability. environmental and civil engineering projects. systems.
Geosynthetic geonets are mainly used for drainage and filtration in civil and environmental projects.
Typical applications include landfill leachate collection, tunnel waterproofing, retaining wall drainage, road sub-base systems, and slope protection, where efficient in-plane water flow is essential.
Most geosynthetic geonets are made from HDPE (High-Density Polyethylene) or sometimes PP (Polypropylene) or PET (Polyester).
These polymers are blended with carbon black and antioxidants to resist UV light, oxidation, and chemical attack, ensuring long-term drainage performance under pressure.
A high-quality HDPE geonet can last over 50 years in normal underground or covered conditions.
When properly installed and protected from direct sunlight, its drainage capacity and structural integrity remain stable even under continuous compressive loads and harsh chemical environments.
Geonet Working Principle
Topsoil / Cover Layer
This surface layer protects the drainage system from mechanical damage and UV exposure. It distributes loads evenly and prevents soil particles from entering the drainage layer.
Nonwoven Geotextile (Filter Layer)
The upper nonwoven geotextile acts as a filter and separation layer. It allows water to pass through while preventing fine soil particles from clogging the geonet core, maintaining long-term drainage efficiency.
HDPE Geonet Core (Drainage Layer)
The core geonet layer consists of intersecting HDPE ribs that form open flow channels. It provides high in-plane transmissivity, allowing rapid leachate or groundwater discharge even under high compressive loads.
Lower Geotextile / Geomembrane Layer (Protection or Barrier Layer)
A lower geotextile or geomembrane beneath the geonet enhances system stability. It prevents downward seepage and protects the subgrade from erosion and saturation.
Working Principle:
The geonet system forms a continuous drainage path between impermeable and permeable layers. Water and gases enter through the upper geotextile filter, move horizontally within the geonet channels, and discharge safely into the collection system—maintaining foundation stability and reducing hydrostatic pressure.
