Manufactured from high-strength precast concrete, our security blocks provide a simple yet highly effective solution for controlling vehicle access, protecting assets and creating secure site boundaries in commercial, construction and infrastructure environments.
What is Security Blocks?
Concrete Security Blocks are solid precast units designed to act as vehicle deterrents, temporary or permanent perimeter barriers, ballast (kentledge) for structural support, access control blocks and site demarcation units. Their substantial mass and durable construction make them suitable for both temporary and long-term deployment.

Installation Overview
Each block has its own lifting and placing system and can be delivered and installed by our specialist team using forklift/telehandler slots, 'Deha' lifting pins or 'Hiab' type clamps. No foundations are required — blocks can be deployed on firm, level ground, making them ideal for rapid deployment. Security blocks can be installed quickly using standard lifting equipment such as forklifts, telehandlers or Hiab cranes, allowing fast response in urgent situations.
Typical Loading Guidance
Technical drawings, dimensions and lifting information are available on request.
Compliance & Technical Support
High-mass precast concrete units suitable for stacking (subject to specification). Compatible with fencing or hoarding systems. Weather resistant and designed for repeated lifting and relocation. Beyond perimeter security, blocks can serve as counterweights for fall-arrest systems, ballast for structures and load anchors for testing and engineering applications. They are built to withstand harsh weather conditions, physical impact and repeated use.
Safety & Responsibility
Concrete Security Blocks are widely used to deter unauthorised vehicle access, define controlled operational zones, protect vulnerable infrastructure, support temporary works and enhance perimeter control strategies. Their substantial physical presence provides both a visual deterrent and practical barrier.
Security planters and blocks contribute to broader safety planning by creating defined vehicle exclusion zones and protecting pedestrian-heavy environments.
Bespoke Options
Available in a range of block styles to suit different applications and threat levels. Blocks can be mixed and matched according to site configuration. Bespoke options include paint finishes in unit or corporate colours, high-visibility markings such as chevrons, and military or organisational branding.

Do concrete security blocks require foundations?
No. Concrete security blocks can be deployed on firm, level ground without the need for permanent foundations, making them ideal for rapid deployment. Suitability should be assessed based on site risk and requirements.
Can they be used for temporary works ballast?
Yes. They are commonly used as kentledge for scaffolding, hoarding and event structures.
Are they reusable?
Yes. Precast concrete security blocks are durable and designed for multiple uses across different projects, offering long-term value.
Can fencing be attached to security blocks?
Yes. They can be integrated with fencing or hoarding systems to enhance site security.

Can different block types be used together?
Yes. Blocks can be mixed and matched to create tailored security solutions depending on site layout, threat level and operational requirements.
How are the blocks moved and handled?
Each block is designed with integrated lifting systems, including forklift and telehandler slots, cast-in lifting pins (Deha) and Hiab-compatible clamp points. This ensures safe and efficient handling on site.
Can security blocks be customised?
Yes. Blocks can be customised with paint finishes in unit or corporate colours, high-visibility markings such as chevrons, and military or organisational branding.
