Gabions are welded wire cages or boxes filled with stone, concrete, sand, or dirt. As a result, gabion is a somewhat flexible block structure utilized in building for slope stability and erosion control.Gabions come in a variety of shapes and sizes, and they're employed in a variety of engineering projects. Live rooted branches are often inserted between the rock-filled baskets to strengthen the gabion's resilience and stability.Its major purpose is to avoid additional damage to water-logged regions by controlling soil sliding on road sides, erosion, and scouring on river banks during floods and high-velocity river flows.
