Drainage Geonet Three-Dimensional Composite Material For Optimal
Drainage And Protection
Product Introduction
The three-dimensional composite drainage net is a new type of
drainage geotechnical material, which consists of a
three-dimensional plastic net with double-sided adhesive permeable
geotextile1. This material has a unique three-dimensional
structure, can withstand high compression loads during the entire
use process, and can maintain a considerable thickness, providing
good water conductivity
Product Application
Widely used in landfill drainage, highway subgrade and pavement
drainage, railway drainage, tunnel drainage, underground structure
drainage, retaining wall back drainage, garden and sports field
drainage and other engineering drainage fields
Product Property
The three-dimensional composite drainage net has high tensile
strength and shear strength, can withstand long-term high pressure
loads, and can maintain a considerable thickness, providing good
water conductivity. In addition, it also has good corrosion
resistance and acid and alkali resistance, and has a long service
life.
