Three-dimensional Composite Drainage Network

Geonet is a geosynthetic material used for drainage, characterized by high drainage efficiency and high strength. Here is a detailed introduction:

Structural Composition

Drainage nets mainly include double-ribbed and three-dimensional geonets. Double-ribbed geonets consist of two intersecting ribs forming drainage channels, providing high longitudinal and lateral drainage capacity. Three-dimensional geonets consist of three ribs arranged at certain intervals and angles to form a three-dimensional spatial structure with drainage channels. The central rib has greater rigidity, forming a rectangular drainage channel.

Material Characteristics

Typically made of high-density polyethylene (HDPE) or polypropylene (PP), it features high permeability, high strength, and corrosion resistance. The material itself is resistant to acid and alkali corrosion and has a long service life.

Performance Advantages

Composite drainage nets use a three-dimensional core structure, typically 5-8mm thick. The central vertical ribs and diagonal supports form continuous drainage channels, achieving a drainage efficiency 5-8 times that of traditional gravel layers, with a drainage capacity of up to 0.3 m³/m² per unit time. The core of the geogrid, composed of HDPE and polypropylene fibers, boasts a bidirectional tensile strength of 20-50 kN/m and a compressive modulus more than three times that of traditional geogrids.
