High - Strength Geotextile Tube Bags
High dewatering efficiency: The moisture content of the slurry can be reduced from 90% to less than 50%, and the speed is 3 - 5 times that of the sedimentation tank;
Convenient construction: Prefabricated production, on - site filling is sufficient, the construction period is shortened by more than 50%, and it is suitable for complex terrains (such as tidal flats and swamps).
Low cost: The material and logistics costs are 30%-50% lower than those of the concrete solution, and the maintenance cost is low;
Environmentally friendly: Recyclable materials account for 90%, reducing the ecological damage of quarrying and supporting vegetation/ecological restoration.
Product Introduction:
High - Strength Geotextile Tube Bags demonstrate multi - dimensional advantages in fields such as water conservancy, environmental protection, and civil engineering.It is woven from synthetic fibers such as polypropylene (PP) or polyester (PET). The tensile strength can reach 10 - 300 kN/m. It is resistant to acids and alkalis, and can withstand ultraviolet aging. The service life can be as long as 10 - 20 years (depending on the environment), and it is suitable for harsh working conditions (such as seawater erosion and contact with industrial wastewater).

High - Strength Geotextile Tube Bags, as a flexible, cost - effective, and ecological engineering material, have significant advantages in fields such as soil and water conservation, coastal protection, and environmental governance. They are particularly suitable for emergency projects, soft foundation treatment, and waste resource utilization scenarios. Their durability depends on the anti - aging performance of the material and construction quality. Under normal circumstances, their service life is 5 - 15 years, and it can be further extended through material modification (such as anti - UV and acid - alkali - resistant formulations) and protective measures. In the future, with the increasing demand for ecological and environmental protection, the application of geotextile tube bags in green infrastructure construction will become more extensive.
