Ballast Blocks for Security and Perimeter Protection
Maintaining secure and controlled site boundaries is critical across renewable energy and construction projects.
Elite Precast ballast blocks provide a robust, non-invasive solution for anchoring fencing, barriers, and security infrastructure, delivering stability, flexibility and ease of deployment without permanent groundworks.
What Are Counterweight Blocks (Kelly Blocks)?
Reliable Security for Temporary and Permanent Sites
From active construction zones to operational renewable energy sites, effective perimeter protection is essential. Elite ballast blocks are manufactured using high-strength precast concrete, providing the weight and durability required to securely anchor fencing and barrier systems in a wide range of environments.

Key Applications
Elite Precast ballast blocks are widely used for:
Fencing Systems
Providing stable anchoring for temporary and semi-permanent fencing to secure site boundaries and restrict unauthorised access.
Barriers and Traffic Control
Supporting pedestrian barriers, vehicle management systems and exclusion zones to maintain safe and organised site operations.
Gate and Access Points
Stabilising temporary gates and entry systems to control site access effectively.
Protective Infrastructure
Securing safety barriers around sensitive equipment, hazardous areas or restricted zones within the site.
Benefits
Ballast blocks eliminate the need for digging, drilling, or concrete pouring, making them ideal for sites where ground disturbance must be minimised. Their fully removable design allows for easy repositioning or complete removal, supporting phased developments and temporary security requirements.
