Porous stones, such as laterite and gravel, are commonly found and used in various construction and geotechnical applications in Bangladesh. These stones, with their high porosity, are often used in drainage systems, foundation beds, and road construction to allow for water movement and prevent soil erosion. In coastal and riverine regions of Bangladesh, porous stones are also essential for flood protection works and embankment stabilization, as they help manage water flow and reduce the risk of seepage and structural failure.
