Geotextile

High-strength polypropylene staple fiber needle-punched geotextile

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.

FREQUENTLY ASKED QUESTIONS



What types of geotextiles are there?

Geotextiles can be divided into two categories according to the manufacturing method: non-woven (non-woven) fabrics and woven (woven) geotextiles. Geosynthetics also include geomembranes, special geosynthetics, composite geosynthetics, etc.



What specifications are there for geotextiles?

Generally, the specifications are distinguished by the mass per unit area. Commonly used specifications are pet200g, pet300g, pet400g, etc. At the same time, its thickness, width, etc. also have different specifications.



What are the colors of geotextiles?

Common ones are white, black, green and gray.



What are the tensile strength and elongation of geotextiles?

The tensile strength and elongation of geotextiles of different specifications will be different. The specific values can be referred to the product description or test report.



How is the price of geotextiles calculated?

The price is usually affected by many factors such as material, specification, production process, market supply and demand, and is generally calculated as a unit price per square meter.
