Geotextile fabric woven filament
Geotextile woven filament fabric is a synthetic fabric made from high-strength, low-elongation filament fibers such as polypropylene and polyester through a weaving process. Typically, it is woven from two sets of filaments. Classified by its intended use, geotextile varieties include single-layer woven geotextile (also known as silt filter fabric), double-layer geotextile (also known as geotextile mat), and woven geomembrane. It is suitable for applications such as slope protection and bank reinforcement in rivers, seas, and coastal areas, as well as water collection areas, revetment protection in harbors, flood prevention and emergency response, reinforcement of embankments and dykes, foundation stabilization of soft soil, construction of cofferdams, and various erosion control projects.

Product performance
1, High tensile, tear, puncture resistance, and other mechanical strengths make it more than twice as strong as geotextiles of equivalent weight made from short fibers. Specifically, it excels in resisting puncture and top bursting forces, with a strength reaching 2200 Newtons or more. In applications such as stone revetment, it effectively prevents irregular stones from impacting the fabric surface.
2, Relying on the mutual compression of warp and weft yarns to maintain structural stability, high-strength woven geotextile is particularly suitable for reinforcement, strengthening, and isolation applications.
3, Excellent chemical resistance; corrosion resistance.
Main Applications
Used for reinforcement in backfilling of retaining walls or as panels for anchoring retaining walls. Also employed in constructing wrapped retaining walls or bridge abutments.
Reinforcing flexible road surfaces, repairing cracks in roads, preventing the reflection of cracks in the pavement, increasing the stability of crushed stone slopes and reinforced soil, preventing soil erosion and frost damage to the soil in low temperatures. It can be used as an isolation layer between road chips and the subgrade, or as an isolation layer between the subgrade and soft foundation. It also can serve as isolation layers between highways, airports, railway ballast, artificial stone heaps, and the foundation. And they are widely used in projects such as highways (including temporary roads), railways, embankments, earth-rock dams, airports, and sports fields to strengthen weak foundations.
Funtions in road construction
Geotextile woven filament fabric plays a crucial role in road construction engineering, primarily contributing to reinforcement, protection, drainage and filatration.
1, Reinforcement: With its high strength and low elongation characteristics, long filament woven geotextile is utilized to reinforce weak foundations in road projects. By laying the geotextile in the subgrade layer, it effectively disperses loads, enhances the bearing capacity of the foundation, and improves overall deformation resistance. This is particularly important for road, railway, and airport projects, especially in regions subjected to heavy traffic loads.
2, Protection: Long filament woven geotextile is employed for protective purposes in road engineering, especially in preventing soil erosion and resisting external environmental threats. It serves as an effective barrier, preventing soil erosion and safeguarding embankments and slopes from rainwater erosion. Additionally, it prevents particles in the foundation from being washed away, contributing to the integrity of the road structure.
3, Drainage: Long filament woven geotextile often possesses good permeability, making it a valuable component of drainage systems. In road projects, it can be used as a drainage layer to help eliminate accumulated water beneath the road surface, prevent water retention, and reduce the saturation of the foundation. This positively impacts the stability, durability, and minimizes muddy conditions on the road.
4, Filtration: Beyond its primary roles, long filament woven geotextile serves as an effective filtration medium. It prevents the migration of fine particles, allowing water to pass through while retaining soil particles. This filtration function is instrumental in maintaining the long-term effectiveness of the geotextile and ensuring the proper functioning of the overall road system.
