Filament geo fabric is made from high-quality continuous polypropylene fibers by the method of forming and consolidating polyester filaments. Its fibers are arranged into a three-dimensional structure. The continuous filament geo fabric material is a new type of building material for geotechnical and civil engineering applications, it is also widely recognized as the choice for drainage applications, pavement interlayers and separation/stabilization beneath paved and unpaved roads. In addition to having good stretch, puncture resistance and other effects, the filament geotextile fabric also has high acid and alkali resistance, aging resistance and other effects. Filament geotextile fabric is widely used for separation, filtration, drainage, protection functions in civil engineering projects.
1. What Is Filament Geo Fabric?
Filament geotextile fabric is a type of geotextile material that is composed of continuous filaments. These filaments are typically made of synthetic materials such as polyester or polypropylene.Filament geotextile fabric is manufactured using a process called extrusion, where the synthetic fibers are extruded and then bonded together to form a strong and durable fabric. The continuous filaments provide excellent tensile strength and dimensional stability to the fabric.
Filament geotextile fabric is commonly used in various civil engineering and construction applications. It is often employed for soil stabilization, erosion control, filtration, drainage, and separation purposes. The fabric’s high strength and resistance to UV degradation make it suitable for long-term applications in challenging environmental conditions.
The properties of filament geotextile fabric can vary depending on factors such as the type of filament material, the weight or thickness of the fabric, and the manufacturing process. Different specifications and grades of filament geotextile fabric are available to address specific project requirements and engineering needs.
2. What Is Filament Geo Fabric Used for?
Filament geotextile fabric is extensively used in civil engineering and construction projects for a variety of purposes. Here are some common applications of filament geotextile fabric:
2.1 Soil Stabilization
Filament geotextile fabric is employed to reinforce and stabilize soil, preventing erosion and maintaining the integrity of the ground. It is widely used in road construction, embankments, and retaining walls.
2.2 Erosion Control
Filament geotextile fabric acts as a protective layer, effectively controlling soil erosion by preventing the washout of sediment caused by water flow. It is applied in slopes, riverbanks, shorelines, and other erosion-prone areas.
2.3 Filtration
Filament geotextile fabric serves as a filter, allowing water to pass through while retaining fine particles. It finds application in drainage systems, subsurface drains, and beneath retaining walls to prevent clogging and ensure efficient water flow.
2.4 Drainage
Filament geotextile fabric facilitates proper drainage by allowing water to pass through while preventing the movement of soil particles. It is utilized in various applications such as subsurface drainage systems, French drains, and road construction to manage water effectively.
2.5 Separation
Filament geotextile fabric is used for separating different soil layers or materials with distinct properties. It prevents the mixing of materials like aggregate and soil, maintaining their individual performance and stability.
2.6 Reinforcement
Filament geotextile fabric provides reinforcement to structural elements such as roads, railway tracks, and foundations. By improving load-bearing capacity and stability, it helps reduce the risk of deformation and failure.
3. What Are Benefits of Filament Geo Fabric for Highway Embankment Reinforcement Project?
Filament geotextile fabric provides several advantages for highway embankment reinforcement projects. Here are some key benefits:
3.1 Enhanced Soil Stability
Filament geotextile fabric reinforces the soil in highway embankments, increasing its stability. By preventing soil movement, it reduces the risk of slope failure and settlement, ensuring the long-term integrity of the embankment structure.
3.2 Erosion Prevention
Highway embankments are susceptible to erosion caused by weather conditions and water runoff. Filament geotextile fabric acts as a protective barrier, shielding the soil from erosion and preserving the embankment’s stability and shape. This minimizes the need for frequent maintenance and repairs.
3.3 Load Distribution
By distributing the load from traffic and other loads across a wider area, filament geotextile fabric reduces stress on the soil. This improves the embankment’s load-bearing capacity, mitigating settlement and deformation issues.
3.4 Improved Drainage
Filament geotextile fabric allows water to pass through while preventing soil particles from moving. This enhances the embankment’s drainage system, facilitating efficient water flow and preventing soil softening caused by water accumulation.
3.5 Construction Efficiency
Filament geotextile fabric is lightweight, flexible, and easy to handle and install. Its ease of use saves construction time and reduces labor costs. It can be quickly deployed, providing immediate reinforcement to the embankment during construction.
3.6 Long-Term Performance
With its durability and resistance to UV degradation, chemicals, and biological factors, filament geotextile fabric maintains its strength and performance over time. This ensures the embankment’s long-term stability and functionality, reducing the need for frequent maintenance.
4. Case Study of Filament Geo Fabric Material for Highway Embankment Reinforcement Project
An existing U.S. highway located in West Bend, South Wisconsin has a poor safety record. the state of Wisconsin The Department of Transportation (WDOT) plans to build a four-lane separate bypass around the city. The new route passes through the edge of Mud Lake, which is a lake full of glaciers. The lake contains important peat deposits.
BPM company recommended providing non-woven geotextile fabric for embank reinforcement. By placing a geotextile fabric layer with high tensile strength at the bottom of the embankment, the stability of the embankment can be improved by increasing the shear strength provided by the geotextile. In addition, theoretically, the geotextile provides additional rigidity to the bottom of the embankment, thereby making the embankment load distribution more even. Since filament geo fabric material should also reduce the shear stress at the interface of the embankment and subgrade, it helps to reduce the possibility of the embankment spreading laterally on the weak subgrade.
American customers and local technicians talked about our company’s recommendations, thinking that our company’s recommendations can solve the problems they are currently facing. So we sent samples of 200, 300, 400 filament geotextile fabric to our customers for testing. After the customer’s inspection, 300g non woven geotextile fabric was ordered for application in the roadbed reinforcement project. Customers were very satisfied with this cooperation.
5. Summary
Filament non woven geotextile fabric is the kind of high performance geotextile materil which has functions of isolation, filtration, drainage, separation, protection and maintenance, etc. Filament geo fabric material is manufactured by the extrusion of fibers which are then laid down on a manufacturing “bed” and then needle punched from both top and bottom to entangle the fibers to produce a dimensionally stable geotextile. filament geo fabric material is widely used for road construction, landfill, cancel, salt pond, etc.
