Defensive barrier is a prefabricated modular system made from welded wire mesh panels combined with heavy-duty geotextile liners. It is classified by unit height, width, and liner material. Filled with sand, soil, or gravel, defensive barriers are used for military defense, flood control, perimeter security, blast protection, and temporary retaining structures. Their rapid deployment, reusability, and high load resistance make them suitable for emergency response and infrastructure protection projects.
