Product
Geonet
Geosynthetic drainage product formed by intersecting polyethylene filaments, providing high in-plane flow capacity with its open net structure.
Product Summary
High transmissivity in-plane drainage
Produced in bi-planar and tri-planar HDPE structures, geonet provides high transmissivity on excavation bases. With its 5–10 mm cross-section, it forms an alternative to traditional aggregate in both mine solution pond drainage and behind-tunnel flow systems.

Technical Approach
Geonet technical features highlighting the product
Achieving a thin cross-section with high hydraulic capacity both reduces structural load and saves space and time in deep excavations; the key to this is long-term creep resistance.
Low permanent compression under pressure (creep resistance)
High HDPE resistance against chemical attacks
Thin cross-section, lightweight structure compared to traditional aggregate
Tri-planar is decisive in deep waste applications
Maintenance of in-plane permeability under high normal stress is ensured by the tri-planar core.
Product Structure
A structure meeting engineering requirements in a single product
Bi-planar geonet features filaments intersecting in two planes, while tri-planar structure features filaments intersecting in three planes. The open mesh structure remains uncrushed under normal load; thus, liquid or gas is drained in a single direction along the layer.
