Geotextile

High-strength polypropylene staple fiber needle-punched geotextile
Due to the use of high-strength polypropylene short fibers and the use of a needle punching process to tightly entangle the fibers, the geotextile has high tensile strength and tear strength and can withstand greater external forces.

Product Description

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.
