Product Introduction:
Dewatering Geotube is a large tubular containment system made of high-strength geotextile fabric, widely used in civil engineering, environmental protection, and marine engineering.
Material Properties
1.High Strength and Durability
Geotextile tubes are woven from high-performance fibers such as polypropylene, offering high tensile strength and low elongation to withstand significant soil and hydraulic pressures. Additionally, the material exhibits excellent resistance to UV rays, acids, alkalis, and microbial degradation, ensuring long-term performance in harsh environments.
2.Permeability and Filtration
The fabric features fine pores that allow water to pass through while retaining solid particles, enabling effective dewatering, consolidation, and pollutant filtration.
3.Customizability
The diameter, length, and shape of the tubes can be tailored to project requirements, with maximum lengths reaching several tens of meters, making them adaptable to diverse site conditions.

Product Applications:
1.Water Conservancy Engineering:
Used in the construction of embankments, seawalls, and slope/bank protection in river regulation projects. Also applied for seepage control in cofferdams.
2.Environmental Governance:
Widely utilized in the treatment of dredged sediments from rivers, lakes, and seas, as well as municipal and industrial sludge. Effectively achieves sludge dewatering and solidification, reducing environmental pollution.
3.Marine Engineering:
Employed in land reclamation, artificial island construction, and coastal protection against marine erosion. Capable of forming artificial coastlines several kilometers long, where natural sedimentation of marine sand occurs behind the structures.
4.Soft Foundation Treatment:
Serves as a material for temporary access roads on soft foundations. By filling and dewatering the geotextile tubes to achieve solidification, a stable road foundation is formed.
