Tank Trap Pyramid Barriers (TTPBs / Dragon's Teeth)
Manufactured at our Shropshire works, our robust Tank Trap Pyramid Barriers or Dragon's Teeth barriers are high-mass precast concrete units designed for vehicle deterrence, perimeter protection and controlled access across the UK.
These distinctive pyramid-shaped barriers provide a strong physical and visual deterrent in environments requiring durable, freestanding vehicle restriction solutions.
Tank Trap Pyramid Barriers (TTPBs), often referred to as Dragon's Teeth, offer a classic yet highly effective anti-tank solution, updated for today's strategic defence challenges. Designed to physically obstruct vehicular assaults by halting, redirecting, or disabling intruding vehicles, these robust barriers are ideal for securing forward operating bases, critical infrastructure, checkpoints and sensitive perimeters.
What is Tank Trap Pyramid Barriers (TTPBs / Dragon's Teeth)?
Tank Trap Pyramid Barriers, also known as Dragon's Teeth Barriers due to their shape, are solid precast concrete units designed to:
Restrict unauthorised vehicle access
Protect sensitive infrastructure
Form defensive perimeters
Define secure boundaries
Support temporary or semi-permanent security strategies
Their angular pyramid shape increases resistance to vehicle movement and prevents easy displacement.
While rooted in Second World War fortifications, famously used along the Siegfried Line, Dragon's Teeth barriers remain relevant in modern defence scenarios for their proven effectiveness in physically denying armoured vehicle movements.

Key Features & Benefits
Available in both single-pyramid (approx. 760 kg) and three-pyramid interlocking units (approx. 2,500 kg).
Why Choose Tank Trap Pyramid Barriers (TTPBs / Dragon's Teeth)?
High-Mass Vehicle Deterrence
Their substantial weight provides effective resistance against vehicle intrusion (subject to site layout and risk assessment).
Freestanding Installation
No excavation or permanent groundworks required in many applications.
Distinctive Visual Presence
The pyramid profile provides a strong, recognisable security statement.
Durable Precast Construction
Manufactured from high-strength concrete for long service life in demanding environments.
Reusable and Relocatable
Can be repositioned or redeployed across multiple sites and projects.
UK Manufactured
Produced to consistent quality standards with reliable supply.
Defence Advantages:
Immediate Tactical Deployment — Ready-to-use modules allow for near-instant perimeter security without complex site prep
Simple Logistics, Minimal Infrastructure — Requires no foundation works, ideal for austere or rapidly shifting operational theatres
High Reusability and Flexibility — Easily deconstructed, relocated and redeployed as mission parameters evolve
Low Logistical Footprint — Modular design and integrated lift points reduce handling complexity and deployment time

Installation Overview
Elite Precast Concrete Tank Traps are engineered to perform in high-exposure environments. Their high-mass presence enhances both physical protection and visual deterrence.
Technical specifications, weights and lifting guidance are available upon request.

Compliance & Technical Support
Cast from 50 N/mm² high-strength concrete. Available in single-pyramid (approx. 760 kg) and three-pyramid interlocking units (approx. 2,500 kg). Each pyramid stands approximately 850 mm high. Units interlock via integrated connectors. Each unit includes pin-anchor lifting points. No foundation works required in most applications.

Safety & Responsibility
Important note — prior to lifting older or pre-used blocks, please check the lifting pin for wear or corrosion and the block for cracks. If the block is cracked or the pin worn, it could fail when being lifted.

Frequently Asked Questions
What are tank traps used for?
They are used to restrict vehicle access, protect infrastructure and create secure perimeters in commercial, industrial and infrastructure environments.
Are Dragon's Teeth suitable for construction sites?
Yes. They are widely used for site boundary reinforcement and vehicle exclusion zones.
Do they require foundations?
In many applications, no. They are freestanding and rely on their weight and shape for stability.
Can they be moved after installation?
Yes. They can be repositioned using appropriate lifting equipment.
Are they suitable for long-term installations?
Yes. Their durable precast construction makes them suitable for both temporary and semi-permanent applications.
Do they provide hostile vehicle mitigation?
They act as a physical vehicle deterrent. Specific mitigation performance depends on configuration and project design.
Do you supply nationwide?
Yes, we supply Tank Traps and Pyramid Barriers across the UK.
What are tank trap pyramid barriers (Dragon's Teeth)?
Tank trap pyramid barriers, commonly known as Dragon's Teeth, are precast concrete obstacles designed to prevent or slow the movement of vehicles, particularly in defence and high-security environments.
Are tank trap barriers effective against modern vehicles?
Yes. Their shape, spacing, and strength are designed to disrupt vehicle movement, making them highly effective as part of a wider hostile vehicle mitigation strategy.
Where are tank trap pyramid barriers typically used?
They are commonly used in military bases and defence installations, forward operating bases (FOBs), border and perimeter security zones, high-security infrastructure sites, and temporary or semi-permanent deployment areas.
Can Dragon's Teeth barriers be deployed quickly?
Yes. As precast concrete units, they can be transported and positioned rapidly using standard lifting equipment, allowing fast deployment in operational environments.
Can the layout of tank trap barriers be customised?
Yes. Barriers can be arranged in different patterns and spacing configurations depending on the level of protection required and the terrain.
Can tank traps be integrated with other security systems?
Yes. They are often used alongside fencing, concrete walling, gates, and other barriers to create layered defence and enhanced perimeter security.
UK Manufacturing & Nationwide Delivery
