Drainage Geonet

Geonet is a synthetic drainage material made from high-quality High-Density Polyethylene (HDPE), often referred to as a “geospacer.” It features centralized HDPE strands with supporting core structures, providing higher transmissivity compared to bi-planar geonets. Geonets are primarily designed to convey fluids and gases efficiently. At GeofanTex Geosynthetics, geonets are available in two types: bi-planar and tri-planar structures.

Rapidly collects and transmits water to prevent water accumulation and reduce hydrostatic pressure.

Provides a continuous pathway for gases to escape, improving stability in landfill and containment systems.

Maintains a stable drainage channel under long-term loads without collapsing.

Enhances the durability and performance of drainage systems in civil and environmental engineering applications.

When used with geotextiles, drainage geonets help prevent soil particle migration while maintaining continuous and efficient drainage performance.

Minimizes pore water pressure, helping protect soil structures and geomembranes.

Drainage Geonet is a bi-planar or tri-planar geonet composed of two sets of diagonally intersecting HDPE ribs with a rounded cross-section. This unique rib structure provides excellent compressive strength and superior long-term creep resistance, ensuring stable drainage performance under sustained loads.
