I. Introduction
Geotextiles, as crucial geosynthetic materials, play an indispensable role in modern civil engineering. Widely applied in water conservancy, transportation, environmental protection, and construction sectors, they offer multiple functions including filtration, drainage, separation, reinforcement, and protection. With sustained global economic growth and continuous infrastructure development, the geotextile industry is embracing broad prospects for expansion.
II. Industry Status
(1) Market Size
The global geotextile market reached $7.88 billion in 2024. In China, after years of development, the industry has established a relatively complete industrial chain with an expanding market scale. From 2020 to 2031, China’s synthetic geotextile market demonstrated steady growth.
(2) Application Fields
Geotextiles serve diverse sectors:
- Water Conservancy: Seepage control, drainage, and reinforcement in dams, reservoirs, and canals.
- Transportation: Subgrade reinforcement, pavement drainage, and slope protection in roads and railways.
- Environmental Protection: Seepage prevention and filtration in landfills and wastewater plants.
- Construction: Basement waterproofing and rooftop greening in buildings.
(3) Production Processes
Primary manufacturing methods include woven and nonwoven processes:
- Woven geotextiles offer high strength and stability through weaving techniques.
