Kentledge Blocks for Traffic Management Systems and Signage
Stable, Compliant Ballast Solutions for Temporary and Permanent Traffic Control
Traffic management systems and roadside signage must remain stable, visible, and secure in all weather conditions. Whether installed on highways, urban streets, rail interfaces, or event sites, these systems are exposed to wind loads, vehicle turbulence, and public interaction. Kentledge blocks provide a reliable, modular deadweight solution for stabilising traffic management equipment without the need for ground penetration or permanent fixings. Manufactured to certified weights and designed for safe handling, kentledge blocks support safe, compliant, and efficient traffic control installations across infrastructure and construction projects.
What Are Kentledge Blocks?
What Are Kentledge Blocks in Traffic Management Applications?
Kentledge blocks are precast concrete units used to provide controlled ballast for temporary or semi-permanent installations. In traffic management and signage applications, they counteract overturning, sliding, and uplift forces acting on:
Temporary traffic signals
Variable message signs (VMS)
Roadside signage
Barrier systems
Speed control equipment
Pedestrian management systems
Their modular configuration allows engineers and traffic planners to calculate and apply precise stabilising loads in line with wind loading and site-specific risk assessments.
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
Key Applications in Traffic Management and Signage
Temporary Traffic Signals and Portable Systems — Kentledge blocks are widely used to stabilise portable traffic lights and signal heads during roadworks and short-term lane closures. They provide dependable ballast where excavation or ground anchors are impractical.
Variable Message Signs (VMS) — Electronic and mobile VMS units require secure foundations to withstand wind and vehicle-generated turbulence. Kentledge blocks provide the necessary mass to maintain stability while allowing rapid deployment and removal.
Roadside and Construction Signage — For temporary warning signs, directional signage, and construction notices, kentledge blocks ensure compliance with stability requirements and reduce the risk of movement or collapse.
Barrier and Pedestrian Management Systems — Kentledge blocks are used to secure temporary barriers, hoarding panels, and pedestrian segregation systems in highways, rail, and urban environments.
Event and Urban Traffic Control — In event management or city centre works, blocks offer a non-intrusive stabilisation method that avoids damage to finished surfaces, utilities, or underground services.
Benefits
Certified Load Accuracy — Manufactured to known weights for precise stability calculations.
No Ground Penetration Required — Ideal for paved roads and sensitive surfaces.
Rapid Installation and Removal — Supports short-term and emergency works.
Reusable Across Projects — Cost-effective for term contracts and framework agreements.
Improved Public Safety — Reduces risk of sign or signal displacement.
Durable Construction — Designed for repeated handling and outdoor exposure.
Engineered for Your Environment
Designed for High-Risk Public Environments
Traffic management installations operate in live, high-risk public spaces. Kentledge blocks are engineered to support safe deployment, including:
Integrated lifting points for mechanical handling
Clear weight identification for site verification
Robust design suitable for repeated transport and repositioning
We work closely with traffic management contractors, highways authorities, and principal contractors to ensure block configurations align with wind loading calculations, national traffic standards, and project-specific method statements.
Bespoke weights and configurations are available to suit specialist signage systems or constrained urban environments.
Compliance and Regulatory Support
Kentledge blocks support compliance with relevant traffic management and temporary works standards, including:
Highway authority guidance
Temporary traffic control regulations
Wind loading and stability requirements
Health and safety legislation
Full documentation, including certified weights and handling guidance, is available to support risk assessments and approvals.
Why Choose Kentledge Blocks for This Application?
Maintaining stable, compliant traffic management systems is essential for public safety and project efficiency. Kentledge blocks provide a simple, reliable, and industry-proven solution for stabilising signage and traffic control equipment without intrusive works.
Their modular, reusable design makes them well suited to highways maintenance, infrastructure upgrades, rail interfaces, and urban construction environments.

Frequently Asked Questions
Are kentledge blocks suitable for highways and live roads?
Yes. They are commonly used for stabilising temporary traffic systems on live highways, subject to site-specific risk assessments and traffic management plans.
Do kentledge blocks damage road surfaces?
When installed correctly and used with appropriate protection where required, blocks do not require ground penetration and minimise surface disruption.
How are stability requirements calculated?
Stability is calculated based on wind loads, equipment dimensions, and site exposure. Known block weights allow accurate determination of required ballast.
Can blocks be reused across multiple projects?
Yes. Reusability makes them ideal for long-term traffic management frameworks and recurring roadwork programmes.
Are kentledge blocks compliant with highway authority requirements?
Yes. When correctly specified and supported by documentation, kentledge blocks are widely accepted for stabilising temporary traffic systems.
Can bespoke sizes be provided for compact or urban sites?
Absolutely. Blocks can be manufactured in varying weights and dimensions to suit restricted access or tight installation areas.
