When hostile forces target infrastructure, barriers must absorb blasts, not just deflect bullets. JOESCO’s HESCO bastions redefine blast resistance through rigorously tested materials and structural engineering. This article details how these barriers withstand IEDs, RPGs, and ballistic threats while optimizing deployment speed and lifecycle costs.
Core Material Specifications: The Science of Stopping Blasts
JOESCO’s blast resistance begins with advanced material science:
- Galvanized Steel Mesh Framework
- Wire Diameter: 4mm to 5mm for optimal shrapnel dispersion
- Mesh Aperture: 76x76mm (3″x3″), balancing projectile arrest and soil retention
- Coating: ZM-Aluminum Galvanization providing 20-year corrosion resistance
- Geotextile Liner
- Material: UV-stabilized non-woven polypropylene
- Function: Filters water while containing compacted fill material
- Fill Material Density: Compacted sand/gravel at 1.8 to 2.0 g/cm³ for effective blast wave dissipation
Blast resistance isn’t just strength—it’s about redirecting energy. HESCO’s mesh fractures projectiles while geotextile-contained fill absorbs shockwaves. — JOESCO Military Engineering Team
Certified Blast Performance Metrics
Third-party validation confirms battlefield performance:
- Ballistic Resistance: Stops 7.62mm rounds
- Blast Overpressure: 15 psi (equivalent to standard IEDs)
- Vehicular Impact: Stops 7-ton truck at 50km/h
- Deployment Speed: 100-meter perimeter in 18 minutes
Key performance technologies:
- Hexagonal cell distribution of blast forces
- On-site soil compaction disrupting shockwaves
- Double-stacked units (2.74m total height) resisting RPGs
ISO-Compliant Manufacturing Specifications
Production meets global security standards:
- Wire Welding: Robotic welding achieves 50 kN/m tensile strength
- Geotextile Seams: Ultrasonic sealing prevents tear propagation
- Standard Heights: 0.61m, 1m, 2.13m (stackable to 4m)
- Custom Sizes: Engineered for curved perimeters or bunker roofs
Field Deployment Protocol for Maximum Resistance
Critical implementation guidelines:
- Prepare level ground below 5-degree incline
- Interlock units with steel hooks maintaining under 5mm gaps
- Compact soil in 15cm layers at 25% moisture content
- Add razor wire or sandbags for fragmentation control
Critical Tip: Use sandy soils (70% sand, 30% silt) avoiding pure clay for optimal compaction.
Lifecycle Cost Analysis: Beyond Initial Specifications
Operational advantages include:
- Reusability: Replace damaged cells in 15 minutes
- Corrosion Warranty: 10-year limited warranty
- Logistics: Folded units occupy 80% less space than concrete
