High-Density Polyethylene Drainage Geonet For Various Applications
Product Introduction
Three-dimensional geogrid cores are a new type of geosynthetic
material, mainly made from high-density polyethylene (HDPE) as the
main raw material, combined with carbon black, ultraviolet
inhibitors, and antioxidants. They are manufactured through a
special extrusion molding process. This material has extremely high
rigidity and good drainage performance. At the same time, the
non-woven geotechnical fabrics with needle-punched holes attached
to both sides have good permeability, mechanical properties, and
chemical stability, as well as a high friction coefficient. This
allows three-dimensional geogrid cores to play an important role in
civil engineering.
Product Application
Darinage for the landfill, roadbed and road surface, railway,
tunnel, underground structure, back of retaining wall, garden and
playground, etc.
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
