CT Blocks FAQs

Counter terror blocks are robust vehicle mitigation units designed to protect public spaces from hostile vehicle attacks. They act as a block vehicle defence barrier, preventing unauthorised vehicles from accessing pedestrian-heavy areas while allowing safe movement for people.

Each counter terror block vehicle defence system is engineered to stop or slow hostile vehicles by absorbing and dispersing impact energy. The independently verified performance of our products ensures they meet recognised security standards and deliver reliable protection.

They are commonly used in markets, high streets, civic spaces, and event locations. Popular applications include areas with high footfall, where protecting market traders, residents, and visitors is a top priority.

Yes. Our designs support planned access routes so emergency services can operate effectively. Maintaining emergency access remains a priority, alongside improving public safety and security.

Unlike temporary barriers, counter terror blocks are purpose-designed for vehicle mitigation. They provide a reasonable balance between security, aesthetics, and usability, making them suitable for long-term public-realm use.

Yes. With artisan precast finishes, counter terror blocks can be tailored to complement surrounding architecture and streetscapes, helping protect public spaces without creating an overtly hostile environment.

In many cases, yes. Where current measures strike an insufficient level of protection, counter terror blocks can enhance or replace existing solutions, ensuring the priority remains on public safety and security.

Rigorous Crash-Test Certification: Specifying PAS 68 Blocks

When sourcing perimeter defence systems for civil engineering tenders or local authority public realm upgrades, verified structural performance under extreme stress is non-negotiable. Broxap’s PAS 68 Blocks and modular HVM Blocks are subjected to physical crash-testing methodologies to guarantee maximum kinetic energy dissipation.

Our precast perimeter blocks can be custom-spaced and specified to align with the exact threat variables calculated in your site's Vehicle Dynamic Assessment (VDA), carrying industry-recognized benchmarks:

  • BSI PAS 68: The primary UK standard verifying impact penetration metrics, vehicle speed limits, and maximum weight thresholds.
  • ISO 22343-1 & IWA 14-1: Global impact specifications certifying vehicle security barriers (VSBs) against deliberate vehicle-borne attacks.

With the passage of the Terrorism (Protection of Premises) Act 2025 (Martyn’s Law), operators of Enhanced Tier venues and high-capacity public spaces are legally required to deploy proactive public protection measures. Our high-mass CT block systems provide an immediately effective, compliant defence line that satisfies commercial risk assessments and strict perimeter security mandates.

 

Commercial Engineering, Finishes & Site Deployment

Our commercial Counter Terror Blocks are manufactured using high-strength, reinforced precast concrete to ensure maximum durability against deliberate environmental wear, tampering, and vehicular force. Designed for flexible real-world deployment, they offer distinct architectural and logistical advantages:

  • No In-Ground Excavation Required: Unlike traditional security arrays, our modular blocks provide high-impact perimeter defence entirely above ground. This makes them the definitive choice for city centers, historic zones, and high-streets (such as Portobello Road) where complex subterranean utility networks completely prohibit subterranean digging.
  • Artisan Precast Finishes: To ensure robust perimeter defence does not create an oppressive environment, our blocks feature premium, exposed aggregate and architectural finishes. They blend naturally into modern streetscapes, acting simultaneously as seating, boundary markers, or architectural features.
  • Rapid Deployment & Scalability: Equipped with integrated lifting points, our interlocking blocks can be swiftly positioned by on-site mechanical equipment. They are highly scalable, operating efficiently as standalone security assets or as a continuous, interlocking perimeter wall for temporary public events or permanent urban schemes.
