In the journey of advancing sponge city construction and solidifying road engineering quality, a seemingly ordinary yet crucial material – geotextiles – is emerging with unprecedented innovative momentum as an indispensable driving force for green infrastructure development. With the accelerated rollout of major domestic municipal and transportation projects, this engineering auxiliary material, boasting excellent properties such as high strength, corrosion resistance, water permeability, and soil retention, has quietly upgraded, infusing various engineering projects with more efficient and greener solutions.

Demand Soars, Industry Enters Rapid Development Phase​​

According to the latest data from the China Nonwovens & Industrial Textiles Association (CNITA), driven by continuous national infrastructure investment and rising environmental requirements, China's geotextile industry has maintained an average annual growth rate exceeding 12% for three consecutive years, with annual output surpassing the million-ton milestone. The market demand structure is also diversifying: the previous pattern relying mainly on hydraulic engineering and landfill anti-seepage/isolation is being broken, now extending widely to high-tech fields such as high-speed railway subgrade reinforcement, coastal embankment ecological protection, urban utility tunnel construction, and mine ecological restoration.

​Exemplary Applications Highlight Value:​​

Hangzhou Asian Games Village Sponge City Transformation:​​ Large-scale use of new composite geotextiles laid beneath permeable pavements successfully achieved on-site infiltration and retention of over 80% of rainwater during recent rainy seasons, thanks to their superior vertical permeability and lateral drainage capacity. This significantly alleviated municipal drainage pressure, providing key technical support for building sustainable ecological communities.

Yunnan Mountainous Highway Slope Reinforcement Project:​​ The project utilized high-strength woven geotextiles combined with anchoring structures for slope protection. This effectively resisted geological creep, successfully preventing threats to road safety from multiple minor landslides, significantly extending the road's service life and reducing maintenance costs.

Sustained Policy Support, Expansive "Geotextile+" Development Space​​

The policy environment continues to release positive signals. Guided by the "dual carbon" goals, environmentally friendly geotextile products with energy-saving and emission-reduction potential will receive more priority procurement in projects and government subsidy support. Furthermore, the "14th Five-Year Plan" explicitly prioritizes building a modern infrastructure system and ecological governance. Projects like sponge cities, the national water network, high-standard farmland, and ecological fragile zone protection and restoration will continuously expand the scale of geotextile demand, with particularly bright prospects for high-end customized application solutions.

Industry Expert Outlook: Driving Development with Innovation, Building Foundation with Quality​​

Industry insiders widely agree that the domestic geotextile industry is at a strategic opportunity period for transformation and upgrading. "Keeping pace with national strategic direction, deeply researching new materials and technologies, and emphasizing the integration of ecological value" are key directions for the industry's future development.

Conclusion​​

From providing silent underground support to shouldering the mission of green development, geotextiles, leveraging their unique functional advantages and continuously updated technological essence, have become the "invisible backbone" fortifying modern infrastructure networks. With breakthroughs in domestic technology, continuous expansion of application territories, and prioritized national policy support, this low-key yet powerful engineering material is weaving a greener, smarter, and more robust blueprint for development across China, continuously aiding high-quality urban and rural development. In the future, propelled by quality enhancement, green transformation, and innovation-driven growth, the geotextile industry is poised for even greater breakthroughs and development opportunities.
