JOESCO HESCO Barrier QS4

​​Product Overview​​

The ​​JOESCO QS4 HESCO barrier​​ is engineered for scenarios requiring exceptional stability and high-volume fill capacity. With a unique width of ​​1.50 meters​​ and a standardized height of 1.0 meter, this 5-cell unit provides 25% greater cross-sectional area compared to standard 1m-wide barriers, resulting in superior resistance to hydraulic pressure and blast forces. The QS4’s design prioritizes rapid deployment without compromising durability, making it ideal for emergency floodwalls, military revetments, and industrial containment projects. Constructed from Galfan-coated steel mesh and UV-resistant geotextile, it accepts a wide rang

e of fill materials—from sand and gravel to recycled concrete—enabling cost-effective installations in remote or resource-limited environments.

​​Key Features & Advantages​​

1. ​​Enhanced Stability from Wider Base​​
   The 1.50m width creates a lower center of gravity, significantly reducing tipping risks on soft or saturated soils. This design is critical for flood zones where water saturation undermines narrow-barrier stability.
2. ​​High-Speed Deployment​​
   A 3-person crew with an excavator can install ​​100 linear meters in under 4 hours​​. Pre-assembled spiral connectors and reinforced corner seams accelerate alignment and interlocking.
3. ​​Multi-Threat Resilience​​
   • ​​Blast Resistance​​: Withstands overpressure up to 10 PSI (equivalent to a 50kg TNT detonation at 15m distance) when filled with compacted sand-gravel mix.
   • ​​Erosion Control​​: Holds against water currents exceeding 2.5m/s, validated in riverbank and coastal applications.
   • ​​Vehicular Impact​​: Stops 5-ton vehicles traveling at 40km/h, suitable for checkpoint security or construction zone protection.

​​Primary Applications​​

​​Technical Specifications​​

• ​​Dimensions​​: 1.0m H × 1.50m W × 5.0m L (per 5-cell set)
• ​​Fill Volume​​: 7.5 m³ per unit (50% more than standard 1m-wide models)
• ​​Mesh Specification​​: 4mm Galfan-coated steel, 75×75mm hexagonal apertures
• ​​Geotextile Liner​​: 400g/m² polypropylene, resistant to UV and chemical degradation
• ​​Stacking Capacity​​: Up to 3 layers high (3.0m total) without external bracing

​​Why Choose QS4 Over Standard Models?​​

• ​​Reduced Installation Time​​: Fewer layers needed to achieve target height—cutting labor by 30% for 2m+ barriers.
• ​​Improved Sustainability​​: Larger fill capacity allows use of low-quality local materials (e.g., clay or rubble) without sacrificing performance.
• ​​Logistical Efficiency​​: Folded units occupy only 15% more space than standard 1m-wide barriers, maintaining transport economy.
