Geotextile bags are fabricated from high strength geotextile fabrics with soil-in-fills. These bags are used to a flexible, monolithic, continuous structure making that is highly resistant to water currents. Sand is widely used as the soil in-fill material because of its low compressibility but other hydraulically pumped soil types can be used. Geotextile bags are relatively smaller sized bags fabricated from appropriate geotextiles and filled with sand or any suitable soil.
Advantages
The geotextile fabrics are used to make geotextile bags that has fine pore sizes to enable retention of the soil-infill but also has high permeability to enable easy exit of water during the hydraulic filling stage.
The geotextile bags have high tensile strength to enable it to resist the tensile stresses occurring during hydraulic filling and maintain its structure shape.
