The functions of the woven bags produced by the manufacturer of woven bags are: anti-seepage and isolation

Application: Geotechnical dams, rock fill dams, masonry dams, and compression concrete dams; Horizontal anti-seepage blanket in front of embankments and dams, and vertical anti-seepage layer on the foundation; Tailings dam, sewage storage dam body and storage area; Construction cofferdam; The widespread application of composite geomembranes in channels and reservoirs has also played a protective role in the ecological environment.

The raw materials used for composite geotextiles should not only consider their physical and chemical properties required in the usage environment, but also pay attention to product costs. In terms of performance, the following aspects are mainly considered:

1.1 Good physical and mechanical properties

The working environment of composite geotextiles is harsh, often soaked in water or laid in soil with high humidity, so it must have good resistance to hydrolysis and wet mechanical properties.

1.2 Resistance to UV radiation, hydrolysis, and high/low temperature

Composite geotextiles need to be exposed to sunlight, so they must have corresponding UV resistance properties; Composite geotextiles need to adapt to the temperature when in contact with materials such as asphalt, and require a high melting point.

1.3 Chemical resistance, corrosion resistance, and mold resistance

Water and soil are very different, some are alkaline, some are acidic, some have high salt content, and some contain various elements, so they must have chemical stability.

1.4 Good permeability

Composite geotextile filtration and drainage both require permeability, therefore it must have good permeability.
