Product Description

Product Overview

3D composite drainage geonet is an advanced geotechnical material engineered for superior drainage performance in demanding applications. This composite structure combines a three-dimensional geotechnical mesh core with needle-punched non-woven geotextile fabric on both sides, creating an efficient drainage system with enhanced structural integrity.

Key Features & Benefits

High tensile strength up to 16 kN/m for reliable performance under load
Excellent drainage capacity with hydraulic conductivity up to 3.0×10⁻³ m²/s
Dual-function design: drainage plus isolation and foundation reinforcement
Corrosion resistant and chemically stable for long service life
Maintains consistent thickness under compression for sustained permeability
