Staple Geotextile Durable and Corrosion-Resistant for Various
Applications
Product Introduction
Staple fiber geotextile is a kind of water-permeable geosynthetic
material made of synthetic fiber by needling or weaving. Its main
raw material is polypropylene or polyester staple fiber, through
opening, combing, clutter, laying nets and other processes to make
cloth.
Product Properties
1. Water permeability: Even under earthwork pressure, it can
maintain good water permeability.
2. Corrosion resistance: Due to the use of polypropylene or
polyester and other chemical fibers as raw materials, so acid and
alkali resistance, no corrosion, no moth, anti-oxidation.
3. Easy construction: light weight, easy to use.
Product Application
Staple fiber geotextile has a variety of uses, can be applied to
water conservancy projects, DAMS, roads, airports and construction
and other fields. It can be used as a material for isolation,
drainage, filtration and protection. In addition, it can also be
used in combination with geomembrane to form impermeable materials.
