HESCO barriers, also known as HESCO bastions or defensive barriers, are modular structures used for protection and fortification purposes. They consist of collapsible wire mesh containers lined with heavy-duty fabric and filled with a variety of materials, such as soil, sand, gravel, or even concrete. The design of HESCO barriers allows for easy transportation and rapid deployment in emergency situations or military operations.

These barriers are widely employed for various protective applications, including military fortifications, flood control, perimeter security, and temporary housing in disaster-stricken areas. In military settings, HESCO barriers are used to create defensive positions, checkpoints, and blast walls to shield personnel and equipment from enemy attacks. In disaster relief efforts, they provide effective flood protection, acting as sturdy levees to prevent inundation. Their versatility, ease of installation, and robust construction make HESCO barriers an essential solution for ensuring safety, security, and stability in challenging environments.
