Black Woven Geotextile
1. UV resistant and aging resistatn: Black fabric can absorb and block UV rays, reducing the aging damage caused by direct sunlight. It maintains stable strength even after long-term outdoor use, extending its service life.
2. Strong grass blocking and easy to maintain: The high-density woven structure combined with black shading characteristics double inhibits the penetration of weed roots, eliminating the need for frequent weeding and reducing maintenance costs in areas such as courtyards and roadbeds.
3. Stable reinforcement and anti settlement : Weaving technology endows high tensile and tear resistance, which can enhance the stability of soil or gravel base after laying, disperse loads, and reduce road and slope settlement deformation.
4. Durable and corrosion-resistant, with wide adaptability: acid and alkali resistance, soil corrosion resistance, and a black appearance that can be hidden in the base layer, suitable for roadbed reinforcement, landscape gravel areas, parking lots, and other scenarios, balancing functionality and aesthetics.
Product Introduction
Black Woven Geotextile (black woven geotextile) is a geosynthetic material that uses high-strength polypropylene (PP) or polyester (PET) filaments as raw materials, is woven and formed through weaving process, and is dyed with black masterbatch and anti-aging treatment. Its surface presents a uniform black color, combining the stability of the woven structure with the special functionality of black fabric. Its core function is to meet multiple requirements such as reinforcement, isolation, grass blocking, and UV resistance in engineering, and is suitable for long-term outdoor exposure scenarios. It is widely used in roadbed, landscape, agriculture and other fields, and is a multifunctional geotechnical material that balances performance and scene adaptability.
Product Features
Strong UV resistance and outstanding durability: Black fabric can efficiently absorb and block UV rays, avoiding material aging and brittleness caused by direct sunlight. Compared with ordinary white geotextile, its outdoor service life is extended by more than 50%. It can maintain stable tensile strength and structural integrity even in high temperature and strong sunlight areas (such as southern outdoor roadbeds and rooftop gardens) after long-term use.
High density grass blocking, low maintenance cost: using precision weaving technology, the fabric pores are fine and uniform, and the black shading property can inhibit weed photosynthesis, double blocking weed root penetration. After laying, there is no need to frequently spray herbicides or manually weed, greatly reducing the maintenance workload and cost of courtyards, parking lot gravel areas, and agricultural planting belts in the later stage.
High tensile strength, tear resistance, and good reinforcement effect: The long filament weaving structure endows the material with excellent mechanical properties, with a longitudinal tensile strength of 40-80kN/m and a tear resistance strength of over 10kN. It can effectively disperse soil, gravel, or vehicle loads, enhance the stability of structures such as roadbeds, slopes, and retaining walls, and reduce engineering damage caused by settlement and deformation.
Corrosion and pollution resistance, suitable for multiple environments: Raw materials are treated with acid, alkali, and corrosion resistance, and can withstand salt, chemical substances, and microbial erosion in soil. They can still work normally in special environments such as saline alkali land, wetlands, and municipal sewage areas; And the black appearance is not easy to stain, and can be hidden in the base layer after laying, balancing functionality and visual cleanliness.

Product Application
Roadbed and Road Engineering: In the roadbed laying of highways and rural roads, it serves as a reinforcement layer to enhance the deformation resistance of the base layer and reduce settlement caused by vehicle rolling; Simultaneously blocking the mixing of roadbed soil and gravel cushion layer, maintaining smooth drainage, and adapting to the concealment requirements of black appearance and road base layer.
Landscape and courtyard scenes: The gravel paths in the courtyard and the gravel layer below the roof garden are laid to block the influx of fine soil particles and block the gaps between the gravel, while maintaining the cleanliness of the landscape through their grass blocking properties; Laying along the flower beds and lawn edges in villa courtyards can replace traditional weed control cloths, providing reinforcement and grass blocking functions, and improving landscape maintenance efficiency.
In the field of agriculture and planting, inter row paving of orchards and greenhouse planting belts is used to suppress weed growth, reduce herbicide use, and allow rainwater infiltration to ensure soil moisture; In the improvement project of saline alkali land, it serves as an isolation layer to block the upward movement of salt, protect crop roots, and adapt to the long-term outdoor exposure environment of agriculture.
Slope and water conservancy protection: In the reinforcement of river and reservoir slopes, it is laid under the gravel protection layer to enhance the slope's resistance to erosion. The black fabric's UV resistance can cope with the outdoor strong sunlight environment of water conservancy projects; In landslide control, it is used as a reinforcing material to stabilize the soil and reduce the risk of geological disasters.
Black Woven Geotextile is made of high-strength PP/PET filament by weaving and anti-aging treatment. With four core advantages of strong ultraviolet resistance, high-density grass resistance, high tensile resistance, tear resistance and corrosion resistance, it has become the preferred geotechnical material for multiple scenes. It can maintain stable performance and reduce maintenance costs during long-term outdoor use, while also ensuring the safety of structures such as roadbeds and slopes through reinforcement and isolation functions. It is also suitable for various scenarios such as roadbeds, roads, landscape courtyards, agricultural planting, and slope water conservancy, achieving the comprehensive value of "reliable performance+scene adaptation+cost optimization", and providing efficient and durable geotechnical solutions for various projects.
