Tank Trap Pyramid Barriers for Access Control Zones
Data Centre Security
Tank Trap Pyramid Barriers (TTPBs), often referred to as Dragon's Teeth, provide an effective solution for vehicle access control in data centres and high-security environments. Designed to slow, direct, and restrict vehicle movement, they play a critical role in protecting sensitive areas while allowing controlled entry.
What Are Tank Trap Pyramid Barriers (TTPBs / Dragon's Teeth)?
Control and Slow Incoming Vehicles
Access points are one of the most vulnerable areas of any data centre. TTPBs help mitigate this risk by:
Reducing vehicle speed upon approach
Forcing directional control through managed routes
Preventing unauthorised or high-speed access
By influencing vehicle behaviour, these barriers create safer, more controlled entry environments.
Supporting Security Response Measures
By slowing and directing vehicles, TTPBs give security and response teams valuable time to act. This enables vehicle checks and verification procedures, rapid intervention in case of suspicious activity, and improved coordination with on-site security systems. This added response window is essential in high-risk, mission-critical facilities.
Designed for Hostile Vehicle Mitigation (HVM)
TTPBs contribute to broader hostile vehicle mitigation strategies by limiting vehicle manoeuvrability, preventing direct access to sensitive zones, and supporting layered security when combined with gates, bollards or fencing. They are particularly effective in entry lanes, checkpoints, and restricted access areas.

Why Choose Elite Precast
With decades of precast expertise, in-house engineering support and a proven delivery record on projects of every scale, Elite Precast is the partner specifiers trust. We pair robust, repeatable manufacturing with the flexibility to engineer bespoke solutions when a standard product will not do.
Key Applications
Data centres require strict control over who and what enters the site. TTPBs enhance access control by creating secure vehicle approach routes, supporting screening and inspection processes, and reducing the risk of vehicle-based threats at entry points.
They are particularly valuable for:
Main site entrances
Delivery and service access points
Restricted operational zones
Benefits
Fast Deployment with No Groundworks
Precast tank trap barriers offer immediate installation advantages: delivered ready for placement, no excavation or permanent fixings required, and quickly deployed to create controlled access routes. This makes them ideal for both permanent installations and temporary security upgrades.
Flexible and Reconfigurable Layouts
TTPBs provide a modular approach to access control, allowing layouts to be adapted as needed: create chicanes or controlled entry lanes, adjust positioning based on traffic flow, and easily relocate or expand security zones. This flexibility is especially useful for evolving data centre sites and phased developments.
Engineered for Your Environment
Built for Strength and Reliability
Manufactured from high-strength precast concrete, TTPBs are designed to perform in demanding conditions:
Resistant to weather and environmental exposure
Capable of withstanding impact and heavy use
Low maintenance with long service life
Their durability ensures consistent performance in critical security applications.
