Geo bags, also known as geotextile bags, are versatile tools widely used in civil engineering, environmental management, and construction projects. Their primary application is erosion control, where they act as barriers to prevent soil displacement caused by water currents, waves, or wind. Geo bags are especially effective in protecting riverbanks, shorelines, and coastal areas from erosion, ensuring long-term stability.

In flood management, geo bags are deployed to create temporary or permanent barriers to contain floodwaters and prevent inundation in vulnerable areas. They are also used in the construction of artificial islands, breakwaters, and seawalls, where they serve as foundational elements.

Geo bags are essential in slope stabilization, helping reinforce embankments and prevent landslides. They are also used in dredging projects, containing dredged sediments and preventing pollution of surrounding water bodies.
