Application
1. PP spunbonded needle punched geotextile is widely used in the field of transportation, such as strengthening, protection, isolation, filtering layer and drainage blind ditch of highway and railway roadbed sliding layer and isolation layer in high-speed railway, the reinforced layer of airport apron and runway, reinforced layer in harbor, especially in the position that direct contact with cement pp nonwoven geotextile must be used, otherwise there will be unnecessary loss.
2. Application in water conservancy: dam construction, reclamation project, anti-seepage engineering, vertical anti-seepage engineering, cement dam reinforcement.
3. In environmental protection works: landfill project, wet gold heap leaching field, solid waste landfill.
As per the difficulty of manufacturing the PP filament nonwoven geotextile, the price is always high in this line. But we always try our best to provide competitive price for this product and hope to create more benefits for the geosynthetics application in the world.
