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
