PET Or PP Filament Geotextile

Product Description

PET Or PP Filament Geotextile

Product Introduction：

Polyester filament geotextile is made of PET or PP as raw material, and is produced by fusing spinning, air flow netting and needling consolidation. Filament geotextile has good mechanical function, good water permeability, corrosion resistance, anti-aging, isolation, filtration, drainage, protection, stability, reinforcement and other functions, can adapt to uneven base, can resist construction external filtration damage, creep becomes smaller, long-term load can still maintain the original function. Even in the environment of nearly 200℃ short-term exposure to its performance is almost unchanged, after a large number of tests and practice has proved that filament geotextile has a excellent natural soil, water and microorganisms long-term corrosion resistance.

Function And Use:

Water conservancy project: seawall, river dike, lake dike standard project; Reservoir strengthening project; Redation works; Flood prevention and rescue.

Highway, railway and airport engineering: soft foundation reinforcement treatment; Slope protection; Prevention reflective crack structure layer; Drainage system; Afforestation divider.

Electrical engineering: basic engineering of nuclear power plant; Thermal power ash dam project; Hydropower project.

For roads, railways, DAMS, coastal beaches and other projects reinforcement, reinforcement, filtration, isolation and protection, especially suitable for saline-alkali marsh, landfill.
