Key Features & Capabilities
Integrated Lifting & Handling Systems
Each unit features forklift/telehandler slots, cast-in “Deha” lifting pins, or Hiab-compatible clamp points—enabling quick, safe, on-site manoeuvring.
Customisable Branding & Visual Markings
Blocks can be painted in unit colours, display Ministry of Transport–approved chevrons or feature corporate/military insignia for enhanced visibility and identification.
Cost-Effective, Reusable Defence Assets
A durable alternative to hiring temporary barriers—these blocks provide long-term value through reuse and redeployment.
Why Defence Planners Rely on These Blocks
Rapid & Flexible Deployment
Deployable on firm, level ground with no foundation required, they are ideal for urgent defence scenarios or dynamic operational environments.
Modular Customisation
Mix and match block types according to threat levels or site configuration—whether blocking vehicular ingress, controlling access points, or stabilising structures.
Sustained Durability in Harsh Conditions
Engineered from dense, high-strength concrete to endure physical impact, weathering, and repeated deployments with low maintenance requirements.
Multi-Role Functionality
Beyond perimeter security, blocks can serve as counterweights for fall-arrest systems, HGV test weights, or ballast for tactical infrastructure.
