Nonwoven Geotextile Polypropylene Black White Color In 150 Gsm For Road And Bridge Construction

Geotextile is an engineering material widely used in civil engineering, ecological restoration and environmental protection. It is usually made of synthetic fibers and has good water permeability, strength and durability. The following is a detailed introduction to the definition, classification, characteristics, application and construction precautions of geotextile.

Geotextile is based on synthetic fibers, has strong water permeability and high tensile strength, can isolate, reinforce and filter soil, and is widely used in road reinforcement, dam anti-seepage, landfill isolation and other scenarios. This lightweight and durable material can reduce soil erosion by 60%, extend the life of the project, and become the core solution for stability and environmental protection in civil engineering.

Application of Geotextile

Geotextiles, as multifunctional engineering materials, are widely used in infrastructure construction, environmental engineering, agricultural production and civil fields, mainly playing the functions of isolation, filtration, drainage and protection. ‌

‌Infrastructure construction‌: ‌Highway and railway engineering‌

As an isolation layer to prevent the mixing of roadbed materials, the Shanghai-Kunming High-speed Railway uses polypropylene woven fabric to reduce roadbed settlement by 38%. ‌‌Needle-punched non-woven geotextiles (permeability coefficient of 1×10 ²cm/s) are used in drainage systems. The Beijing-Hong Kong-Macao Expressway expansion project solves the problem of softening the base by laying 300g/m² polyester geotextiles. ‌‌

‌Water conservancy projects‌: ‌Composite geotextiles (600g/m²) are used in the Three Gorges Reservoir area to achieve an anti-seepage strength of 0.3MPa to prevent bank slope collapse. ‌‌

The Yellow River flood control project uses woven geotextiles to make soft drainage, reducing costs by 45% and resisting scouring at a flow rate of 4m/s. ‌‌

‌Environmental Engineering‌:

‌Landfills

Guangzhou Xingfeng Landfill uses a composite system of bentonite waterproof blanket and HDPE membrane, with a leachate collection rate of 99.7%. ‌‌During the restoration of the Luzhai phosphogypsum slag field in Guangxi, 400g/m² geotextiles were used in combination with crushed stone cushion to improve the stability of the dam. ‌‌

‌Mine Ecological Restoration‌

The Inner Mongolia rare earth mine project uses grass seed belt geotextiles, and the vegetation coverage rate reaches 85% within 6 months. ‌‌

‌Agricultural Production‌:

‌Gardening Ground Fabric System‌

Black PP woven fabric (100g/m²) inhibits 95% weed growth, and the vegetable base reduces weeding costs by 70%. ‌‌

‌Aquaculture‌

The breeding ponds made of HDPE anti-seepage geotextiles are salt-alkali resistant and have a lifespan of 10 years. The Wenchang breeding farm in Hainan has increased the water exchange efficiency by 40%.
