Temporary and Permanent Ballast Solutions from Elite Precast
Temporary and Permanent Ballast Solutions from Elite Precast
Our counterweight blocks provide a proven, reliable solution for both temporary and permanent structural ballast applications.
Designed to deliver consistent mass and resistance, our precast concrete counterweight blocks are widely used where stability is required without ground penetration, excavation or permanent fixings.
Manufactured in the UK to exacting standards, Elite Precast counterweight blocks are suitable for a broad range of industries including construction, civil engineering, utilities, renewables, infrastructure, events and modular construction.
What Are Counterweight Blocks (Kelly Blocks)?
What Is Structural Ballast?
Structural ballast is mass added to a structure or system to resist forces such as wind load, uplift, overturning moments or lateral movement.
In many modern applications, ground anchoring is either restricted, impractical or undesirable. In these cases, precast concrete counterweight blocks provide a safe and effective alternative.
By using ballast rather than fixings, projects benefit from faster installation, reduced ground disturbance and improved flexibility for future removal or reconfiguration.
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
Applications for Counterweight Ballast
Elite Precast counterweight blocks are commonly used as ballast for:
Temporary and permanent buildings
Modular and portable structures
Cranes and lifting equipment
Hoardings, fencing and perimeter systems
Signage, lighting columns and street furniture
Renewable energy installations
Temporary works and site compounds
Event infrastructure and temporary venues
Each application may require a different block weight or configuration. Our technical team can advise on suitability based on load, environment and duration of use.
Benefits
For temporary installations, counterweight blocks offer rapid deployment and easy removal without leaving permanent ground damage. This makes them ideal for construction sites, events, temporary buildings and short-term infrastructure projects.
Key advantages include:
No excavation or foundations required
Fast installation and decommissioning
Reduced reinstatement costs
Reusable across multiple projects
Suitable for restricted or sensitive sites

Frequently Asked Questions
What is the difference between temporary and permanent ballast?
Temporary ballast is intended for short-term use and easy removal, while permanent ballast provides long-term stability. Elite Precast counterweight blocks are suitable for both applications.
Do counterweight blocks replace foundations?
In some applications, yes. Counterweight blocks are commonly used where foundations are impractical or not permitted, but structural suitability must be confirmed by an engineer.
Can counterweight blocks be reused?
Yes. Our precast concrete counterweight blocks are designed for repeated use across multiple projects, however you must check the lifting pins before moving the blocks.
Are counterweight blocks suitable for high wind areas?
They are frequently used to resist wind and uplift forces. Required block weight and configuration should be determined by structural calculations.
Do the blocks require fixing to the structure?
This depends on the application. Some systems rely purely on mass, while others may incorporate brackets or restraints.
Are lifting points included as standard?
Yes. All Elite Precast counterweight blocks include integrated lifting points for safe handling.
Can you deliver across the UK?
Yes. We offer nationwide delivery with reliable lead times.
