Description
What is Hesco Barrier / Hesco Bastion?
HESCO Barrier, also known as HESCO Bastion or Concertainer, is a modular and rapidly deployable containment system. It consists of collapsible wire mesh cells lined with durable fabric. Users fill these cells with soil, sand, or gravel to quickly form scalable, robust walls.
Originally designed for military force protection, Hesco barriers effectively shield against blasts and small‑arms fire. They are also widely adopted for civilian use in flood control, erosion prevention, and emergency response projects. The system provides a flexible solution for building temporary or semi‑permanent protective structures with minimal labor and time.

What are the primary advantages of using Hesco Unit over traditional sandbags?
Hesco barriers deploy far faster than sandbags. A small crew using a tractor can fill a single unit in minutes, achieving protection equal to thousands of hand‑filled sandbags. The integrated wire‑mesh structure prevents slumping and maintains stability even under high pressure.
Their modular, stackable design allows building tall perimeter walls or tiered defensive positions. This structural integrity provides superior performance under environmental stress or direct impact, making Hesco units more reliable and effective than traditional sandbag walls.
What materials can be used to fill Hesco Barriers?
Users can fill Hesco units with various on‑site granular materials. Common options include sand, earth, gravel, crushed rock, and small rubble. The fill material should be dense enough to ensure stability and protective capability.
For flood defense, clay or soil reduces seepage effectively. In military applications, clean sand or gravel absorbs kinetic energy from projectiles and mitigates blast fragmentation. This flexibility allows Hesco barriers to adapt to diverse operational needs.
How long do Hesco Barriers typically last once deployed?
Standard Hesco barriers typically last 2 to 5 years in harsh outdoor conditions. Their geotextile lining includes UV protection to resist sunlight degradation. The wire mesh structure remains intact for a longer period.
For long‑term use, crews can apply protective measures like shotcreting (spraying concrete) or adding cladding. These treatments extend service life to decades. Without extra protection, the fabric may weaken over time, but the wire frame continues to provide structural support.
Are Hesco Barriers reusable or easy to remove?
Most modern Hesco units feature a reusable design. A specialized pin mechanism allows the mesh panels to open, releasing the fill material quickly. This makes decommissioning fast and environmentally friendly.
Once emptied, the wire frames collapse into a flat‑pack state for easy transport and storage. The geotextile liner may require replacement if damaged during filling or extended use, but the overall system supports efficient reuse and removal.
