Counterweight Blocks for Hoardings, Fencing and Barrier Systems

Counterweight Blocks for Hoardings, Fencing and Barrier Systems

Reliable Ballast Solutions for Temporary and Permanent Perimeter Installations

Elite Precast counterweight blocks provide a safe, effective and industry-proven solution for hoardings, fencing and barrier system ballast. Designed to deliver consistent weight and stability, our precast concrete counterweight blocks are widely used on construction sites, infrastructure projects, public spaces and events where secure perimeter control is required without ground penetration. Manufactured in the UK to strict quality standards, Elite Precast counterweight blocks help contractors and system providers meet safety, compliance and programme requirements across both temporary and long-term installations.

What Are Counterweight Blocks (Kelly Blocks)?

Why Hoardings and Fencing Require Ballast

Hoardings, temporary fencing and barrier systems are exposed to wind loads, crowd pressure and accidental impact. On many sites, excavation or ground fixing is restricted due to underground services, hardstanding, public access or reinstatement requirements.

Precast concrete counterweight blocks provide structural ballast by adding mass at ground level, improving resistance to overturning and lateral movement while avoiding the need for ground penetration. This makes them ideal for urban, brownfield and high-traffic environments.

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

Elite Precast counterweight blocks are commonly used with:

  • Construction site hoardings

  • Temporary and permanent fencing systems

  • Pedestrian and traffic barrier systems

  • Security fencing and perimeter protection

  • Public realm and highways projects

  • Event fencing and crowd control barriers

  • Temporary screening and privacy hoardings

Blocks can be configured to suit straight runs, corners, access points and high-wind locations.

Temporary Hoardings and Fencing

For short-term installations, counterweight blocks allow rapid setup and removal without permanent ground damage. This is particularly beneficial on construction sites, highways works and event locations. Key benefits include:

  • No excavation or foundations required

  • Fast installation and repositioning

  • Reduced reinstatement costs

  • Suitable for hardstanding and paved areas

  • Reusable across multiple projects

Permanent and Long-Term Installations

Counterweight blocks are also used for long-term hoardings and fencing where ground penetration is not permitted or desirable. Manufactured from high-strength concrete, Elite Precast blocks provide durable, weather-resistant ballast suitable for extended service life. Long-term advantages include:

  • Consistent, engineered mass

  • High resistance to wind and impact loads

  • Minimal maintenance requirements

  • Compliance with UK construction and safety standards

  • Cost-effective alternative to traditional foundations

Benefits

  • High-density concrete for dependable ballast performance

  • No ground penetration – ideal for restricted or sensitive sites

  • Integrated lifting points for safe handling and placement

  • UK manufactured for quality assurance and reliable lead times

  • Flexible sizes and weights to suit different fencing and hoarding systems

  • Reusable and sustainable solution for modern site management

Engineered for Your Environment

Design, Safety and Compliance

Elite Precast counterweight blocks are produced under strict factory quality control and in line with relevant British Standards and industry best practice. Integrated lifting points support safe handling in accordance with site lifting plans and health & safety requirements.

Ballast requirements for hoardings, fencing and barrier systems should always be confirmed by a competent engineer, taking into account wind loading, location, height and duration of installation.

Frequently Asked Questions

Why are counterweight blocks used for hoardings and fencing?

They provide stability and resistance to wind and lateral forces without the need for ground penetration or excavation.

Are counterweight blocks suitable for temporary fencing?

Yes. They are ideal for temporary fencing and barrier systems and can be reused across multiple sites.

Can counterweight blocks be used for permanent hoardings?

Yes. They are commonly used for long-term installations where traditional foundations are not feasible.

Do counterweight blocks need to be fixed to fencing systems?

This depends on the system design. Some rely on mass alone, while others incorporate brackets or restraints.

Are lifting points included as standard?

Yes. All Elite Precast counterweight blocks include integrated lifting points for safe handling.

Are counterweight blocks suitable for high-wind areas?

They are frequently used in exposed locations, but required weight and spacing should be determined by engineering calculations.

Do you deliver nationwide?

Yes. Elite Precast supplies counterweight blocks across the UK using trusted logistics partners.
