Geonet Node: The Core of High-Performance Drainage Systems
Geonet node design directly affects the drainage efficiency, compressive strength, and long-term stability of geonet drainage systems. If you are selecting geosynthetics for landfill, retaining wall, mining, or infrastructure projects, understanding how node geometry influences hydraulic performance can help you choose the right product. This guide explains the structure, applications, key performance factors, and practical selection tips for modern geosynthetic drainage products. What Is a Geonet Node? A geonet is made from interconnected HDPE ribs that create continuous channels for water flow. These rib intersections form a rigid framework that supports the drainage network and helps maintain its shape under load. Unlike geotextiles, which mainly provide filtration and separation, geonets are designed for in-plane water transmission. The geometry, thickness, and spacing of each node determine how well the drainage channels remain open under long-term loading....
