Needle Punched Geotextile For Embank Reinforcement in Thailand

Needle Punched Geotextile is often made of high quality short polypropylene or polyester fibers by  needle-punched or heat-bonded methods to form multi  dimensional network. BPM needle punched geotextile is the robust and durable geo fabrics designed to increase maximum slope support, soil stabilization, erosion control and ground support in a given location such as typically river or reservoir embank. Needle punched geotextile can take the place of the traditional engineering materials in many projects. Our needle punched geotextile stabilization fabric is widely used for filtration, separation, protection, drainage applications in civil environmental engineering and construction projects.

The Advantages of Needle Punched Geotextile

• Engineered to provide high strength and high elongation to ensure excellent resistance to damage during construction.
• Manufactured from high tenacity UV stabilized virgin polypropylene or polyester fibers which have been heavily drawn to ensure excellent long term durability in all soil types.
• Manufactured using a randomly orientated web to provide completely isotropic properties, ensuring that high strength is not limited to a single direction.
• Excellent uniformity with high permeability and low pore size for soil filtration.
• Supplied to a maximum width of 6.5 meters, ensuring minimum waste over large construction areas.
• UV and hot resistant and biological degradation resistant.

What are the applications of Needle Punched Geotextile?

Needle-punched geotextiles, which are non-woven fabrics formed by mechanically entangling fibers using a needle-punching process, have a wide range of applications in industrial projects. These geotextiles offer several benefits, including improved soil stability, filtration, drainage, and erosion control. Here are some specific industrial applications:

1. Soil Stabilization

• Road Construction: Needle-punched geotextiles are used as a separation layer between different soil strata to prevent the mixing of incompatible materials, thus stabilizing the roadbed.
• Railway Embankments: They help reinforce the subgrade soil, providing additional support to the tracks and preventing soil deformation.

2. Erosion Control

• Mining Sites: In areas where vegetation has been removed due to mining activities, these geotextiles can protect the exposed soil from wind and water erosion.
• Construction Sites: During construction, they can be laid on slopes to prevent soil erosion and manage stormwater runoff.

3. Drainage Systems

• Lining Material: Needle-punched geotextiles can be used as a filter layer in drainage systems, allowing water to pass through while preventing soil particles from clogging the system.
• Retention Ponds: They can be placed at the bottom and sides of retention ponds to improve the structural integrity and reduce seepage.

4. Waste Management

• Landfill Liners: Used as a protective barrier in landfills, preventing leachate (liquid waste) from contaminating the surrounding environment.
• Cover Systems: Placed over landfills to minimize gas emissions and control surface water infiltration.

5. Industrial Flooring

• Anti-Slip Mats: In industrial settings, needle-punched geotextiles can be made into anti-slip mats for workstations, walkways, and ramps to enhance worker safety.
• Floor Insulation: They can also provide thermal insulation when used as underlayment for flooring systems.

6. Agriculture and Horticulture

• Protective Coverings: Used to cover plants and crops, protecting them from frost, pests, and UV radiation.
• Weed Control: Laid down in greenhouses or nurseries to suppress weed growth and retain soil moisture.

7. Water Treatment Facilities

• Filter Media: Employed in water treatment plants to remove suspended solids and particulates from wastewater before it is discharged or reused.

8. Geotechnical Engineering

• Reinforcement: Incorporated into soil structures to increase their load-bearing capacity and reduce settlement. This is particularly useful in the construction of retaining walls, embankments, and foundations.

9. Environmental Protection

• Oil Spill Cleanup: Used in oil spill scenarios to absorb and contain spilled oil, preventing it from spreading further and aiding in its cleanup.

10. Infrastructure Development

• Bridge Abutments: To prevent soil erosion around bridge abutments and ensure the stability of the structure.
• Canal Liners: As liners for canals and waterways to control seepage and maintain the integrity of the channel.

Case Study Of Needle Punched Geotextile

Needle punched geotextile can isolate, protect and reinforce the embank. Needle punched geotextile and other geotextiles have good  permeability and coefficiency compared to that of coarse sand, and they can maintain good capillary action without clogging. On the other hand, geotextiles have hydrophilic properties. It is less hydrophilic than soil and thus can reduce capillary rise height. Therefore, it is an indisputable fact that the needle punched geotextile can play a major role in the foundation reinforcement. The application of geotextiles can greatly enhance the embank stability and safety. According to the geotechnical fabric manufacturers’ experience in reinforcing embank construction, in addition to meeting the percolation requirements, the needle punched geotextile should be laid with a thin layer of sand on top of it, which is generally 8-9 cm thick, to achieve more satisfactory results.

Our Thailand customer sent us an inquiry about needle punched geotextile used for embank reinforcement project. We sent him our geotextile manufacturing videos, pictures and certificates. He was very satisfied with these information. Then we sent our professional short fiber non woven geotextile quotation sheet and more details of project design by communication and negotiation quickly. Finally, he placed the order for 250 GSM needle punched geotextile of three 40HQ containers.
