Acid And Alkali Resistant To Aging High Strength Geotextiles Used In Landfill Tailings Ponds
Product Introduction
Filament geotextile, also known as filament geotextile or polyester filament needled geotextile, is a geosynthetic material widely used in geotechnical and civil engineering. It is made by means of polyester filament mesh and consolidation, and has a three-dimensional structure.
The fiber arrangement of this material provides good mechanical properties, longitudinal drainage properties and elongation properties, as well as high chemical stability such as biological resistance, acid and alkali resistance and aging resistance.
Product Properties
High strength, weather resistance, water drainage, corrosion resistance, ductility, durability.
Product Application
1. Hydraulic engineering: used for dam and slope protection filtration, channel isolation and seepage prevention.
2. Infrastructure construction: foundation isolation, reverse filtration, drainage, soil slope, retaining wall and pavement reinforcement, drainage of roads, railways, airport runways.
3. Port engineering: soft foundation treatment, beach embankment, harbour pier and breakwater reinforcement, drainage.
4. Landfills and mine tailings DAMS: isolation and seepage prevention.
5. Agriculture and forestry: reservoir area, river and lake slope protection, green separation belt, environmental protection lawn of non-woven fabrics.
