Product Description

Drainage Geonet for Highway Subgrade and Engineering Applications

This three-dimensional composite drainage net is an advanced geotechnical material featuring a geonet core with needle-punched perforated non-woven geotextiles on both sides, designed for superior drainage performance in demanding engineering environments.

Key Features and Benefits

Exceptional drainage capacity equivalent to one meter thick gravel drainage
High tensile strength withstands long-term pressure loads up to 14 KN/m
Corrosion resistant with excellent acid and alkali resistance for extended service life
Easy installation reduces construction time and lowers project costs

Applications

Ideal for landfill drainage, highway subgrade and pavement systems, railway infrastructure, tunnel projects, underground structures, retaining wall back drainage, and sports field drainage applications.
