JOESCO HESCO Barrier QS12 – High-Strength Versatile Barrier for Military & Flood Control

2025-10-15

Product Overview

The JOESCO QS12 HESCO barrier is engineered for scenarios requiring a balance of height, stability, and rapid deployment. With dimensions of 2.21 meters in height, 1.0 meter in width, and 5.0 meters in length, this 5-cell unit delivers robust protection against blasts, ballistic threats, and flood surges. Its design prioritizes ease of handling while maintaining structural integrity, making it ideal for military perimeters, erosion control, and temporary security zones. Constructed from Galfan-coated steel mesh and a heavy-duty geotextile liner, the QS12 can be filled with on-site materials like sand, gravel, or crushed rock. The barrier’s 2.21-meter height provides superior vertical coverage, while the 1.0-meter width ensures stability on varied terrain. Deployment is streamlined with pre-assembled connectors, enabling a small team to install 100 linear meters in under 4 hours using standard excavation equipment .

Key Features & Advantages

Optimized Height-to-Width Ratio

The 2.21m height offers enhanced protection against climbing attempts and projectile threats, while the 1.0m width provides a stable base resistant to tipping. This balance is critical for slopes or soft soils where narrower barriers might fail.
Rapid Deployment

A 3-person crew can deploy 100 meters of barrier in under 4 hours. Spiral connectors and reinforced seams simplify alignment, reducing installation time by 30% compared to traditional methods.
Multi-Threat Resilience
- Blast Resistance: Withstands overpressure up to 10 PSI when filled with compacted sand-gravel mix.
- Flood Control: Holds against water currents up to 3m/s, suitable for riverbanks and coastal areas.
- Vehicle Impact: Stops 5-ton vehicles at 40km/h, ideal for checkpoints or construction sites .

Primary Applications

Military Base Security: Creates high perimeter walls to protect against blasts and unauthorized access. The height deters climbing, while the fill absorbs ballistic impacts.
Flood and Erosion Control: Used to build temporary levees or stabilize slopes. The 5.0m length allows for efficient coverage of large areas.
Industrial Sites: Secures hazardous zones or contains debris during construction. The barriers can be stacked for added height or arranged in curves .

Why Choose the QS12?

The QS12’s 2.21-meter height provides a strategic advantage in vertical protection without compromising deployability. For example, on a 30-degree slope, the 1.0m width minimizes the need for additional anchoring, cutting installation time by 20% versus taller, narrower barriers. Its reusable design allows for relocation across projects, reducing costs by 50% over concrete alternatives.

Comparison with Other Models

Metric	QS12 (2.21m H, 1.0m W)	Standard 1.5m-High Barrier
Vertical Coverage	47% more coverage	Baseline
Stability	1.5x higher on slopes	Limited to 15° inclines
Deployment Time	4 hours/100m	5+ hours/100m

Deployment Guide

Site Prep: Clear debris and level the ground. On slopes >20°, use TerraLock anchors.
Unfold and Connect: Expand units and link with spiral connectors. Ensure gaps are <5mm.
Filling: Use local materials—compact in 30cm layers for maximum density.

Pro Tip: For blast protection, mix sand with rubber crumb (70:30 ratio) to enhance fragmentation absorption.
