Strong And Durable Drainage Geonet For Various Construction Projects And Applications
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 Property
♦ Strong drainage: strong drainage is equivalent to one meter thick gravel drainage
♦ High tensile strength: can withstand high pressure load for a long time Corrosion resistance
♦ Acid and alkali resistance: has a long service life
♦ Convenient construction: convenient construction can shorten the construction period and reduce costs
Product Application
Darinage for the landfill, roadbed and road surface, railway, tunnel, underground structure, back of retaining wall, garden and playground, etc.
