High-strength polypropylene staple fiber needle-punched geotextile has various application scenarios:
In port engineering:
Used to reinforce the foundation of dock yards and improve load-bearing capacity.
As a protective layer for breakwaters, it resists the impact of waves.
In mining engineering:
Used for reinforcement and anti-seepage of tailings dams to ensure the safety of tailings ponds.
Protect open-pit mine slopes to reduce ore slippage and soil erosion.
In tunnel projects:
As the waterproof layer and reinforcing layer of tunnel lining, it improves the waterproof performance and structural strength of the tunnel.
In artificial lakes and landscape projects:
Used for anti-seepage and reinforcement of lake bottoms and revetments to maintain the stability of water bodies.
