Special Geotextile For Salt Alkali Marsh Of Tailings Pond In
Landfill
Product Introduction
Long fiber geotextile is a widely used geomaterial, which is mainly
made of polyester chips through drying, melting, spinning, laying
and other processes, with high original strength and high
temperature resistance, even at high temperatures can maintain a
complete structure and original physical properties.
Product Properties
High strength corrosion resistance, water permeability,
adaptability, a wide range of applications.
Product Application
High strength long fiber geotextile is widely used in geotechnical
engineering because of its unique properties. It can be used for
anti-filtration protection of retaining wall, road slope, reservoir
dam, earth and rock cofferdam, tunnel and drainage ditch; It is
also widely used in the subgrade drainage of roads and railways. In
addition, it is also suitable for the isolation and protection of
construction cofferdams, docks, anti-slope embankments and other
projects.
