The Hesco Bastion (also known as Concertainer or MIL unit) is a modern military fortification system consisting of a collapsible wire mesh container with heavy-duty geotextile lining. Designed for rapid deployment β a single unit expands to create a 1m x 1m x 1m protective barrier when filled with sand, soil, or rubble.
## Rapid Deployment Advantage
The defining feature of Hesco barriers is deployment speed:
- **Pre-Assembled**: Units arrive flat-packed and pre-connected. One person can unfold a 20-unit section in 10 minutes.
- **No Foundation**: Place on any flat ground. No excavation or concrete needed.
- **Fill On-Site**: Use local material (sand, soil, gravel, rubble). No material transport needed.
- **20x Faster Than Sandbags**: A 100m blast wall requires 10,000 sandbags and 50 man-hours. Hesco: 100 units, 2 man-hours.
## Construction
- **Mesh**: Welded zinc-aluminum coated steel wire mesh (4.0mm wire, 75mm x 75mm opening)
- **Lining**: Heavy-duty non-woven polypropylene geotextile (UV-stabilized, 200g/m2)
- **Configuration**: Multi-cell design β cells connected by internal diaphragms preventing fill migration
- **Color**: Beige/green geotextile (standard). Custom colors available.
- **Coating**: Zinc-Aluminum (Zn-5%Al) β 2x corrosion resistance of pure zinc
## Key Advantages
- **Blast Protection**: Absorbs blast overpressure and fragmentation. Used for personnel bunkers and vehicle barriers.
- **Ballistic Protection**: Filled with sand/soil, provides NIJ Level III ballistic protection against small arms.
- **Flood Control**: Rapidly deployable flood barrier. 1m high wall in hours, not days.
- **Reusable**: Geotextile and mesh durable for 5+ deployments if not damaged.
- **Compact Storage**: Flat-packed β 20 units fit in 1m3. Air-transportable.
- **Environmentally Neutral**: Uses local fill material. No concrete or asphalt. Site restoration: empty and remove.
