Geobags are durable geosynthetic containers fabricated from high-strength woven or non-woven geotextiles and filled with sand or soil. They are designed for erosion control, shoreline protection, and hydraulic structures, providing effective energy dissipation against waves and currents. Geobags are widely used in coastal protection, riverbanks, flood mitigation, temporary bunds, and scour protection works, offering a flexible, cost-effective, and environmentally friendly solution.
