Counterweight Concrete Blocks for Event Infrastructure, Crowd Control and Safety

Counterweight Concrete Blocks for Event Infrastructure, Crowd Control and Safety

Safe, Stable Foundations for Temporary Event Environments

Elite Precast Concrete manufactures robust counterweight concrete blocks designed to provide reliable ballast for event infrastructure, crowd safety and control systems. Our solutions support the safe installation of temporary structures and barriers where permanent foundations are neither practical nor permitted. From large-scale public events, such as the 2012 London Olympics, to controlled access zones during Covid, counterweight blocks play a vital role in maintaining safety, stability, and compliance in dynamic, high-footfall environments.

What Are Counterweight Blocks (Kelly Blocks)?

Counterweight concrete blocks are used to stabilise temporary event infrastructure by resisting wind loads, crowd pressure, and accidental impact. Their mass-based design provides dependable restraint without excavation or ground penetration, making them suitable for both urban and greenfield locations.

Engineered for Your Environment

Design and Safety Considerations

Elite Precast Concrete understands the safety-critical nature of event environments. Our counterweight blocks can be incorporated into event risk assessments and temporary works designs, with key considerations including:

  • Wind exposure and site conditions

  • Barrier height, spacing, and configuration

  • Expected crowd density and movement

  • Load paths and overturning risk

  • Compatibility with fencing or barrier systems

Custom block sizes, weights, and lifting features can be supplied to suit specific event infrastructure requirements.

Supporting Safe and Responsible Event Delivery

Counterweight concrete blocks offer a practical solution that aligns with modern event safety and sustainability expectations:

  • No excavation or surface damage

  • Suitable for short-term and recurring events

  • Enables full site reinstatement post-event

  • Reduces reliance on disposable or ad-hoc ballast solutions

This makes them a trusted choice for event organisers, local authorities, and security planners.
