Gradus Block
Ballast block for temporary fencing and hoarding
The Gradus Block is a high-visibility ballast system designed to provide stability for temporary fencing and hoarding. Used widely on construction sites, roadworks, and event perimeters, it improves site safety by reducing the risk of panels toppling in windy or exposed conditions.
Manufactured from durable, UV-resistant MDPE, the block can be supplied pre-filled with concrete (44 kg) or filled on site with water (20 kg). Its stackable design allows additional ballast to be added where required, while built-in handles make it easy to carry, position, and remove.
The Gradus Block is compatible with standard fence feet and hoarding systems, fitting directly over the panel base for fast and secure installation. Its bright yellow colour ensures high visibility, with custom colour options available to suit site or branding requirements.
