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.
