Gabion blast walls, also known as bastion barriers, are defensive protection systems composed of welded wire mesh panels connected by spiral joints. The units are lined and filled on-site with sand, soil, or stones to create a solid protective structure.
Designed for rapid deployment and high-impact resistance, gabion blast walls provide reliable protection against explosions, ballistic threats, floods, and severe storms.
