Slot Block Water Barriers are water-filled barriers designed for UK site perimeter fencing. They attach to standard temporary mesh fencing to stabilise the base and remove trip hazards, providing a practical, safety-focused solution for site managers and contractors.

• UK design: Specifically developed to meet UK site standards and operational practices.
• Size: Each block measures 1.75 m in length when filled with water, aligning with standard fence panel layouts.
• Colours: Available in red or white for clear visibility on busy worksites.
• Weatherproof: Built to withstand outdoor conditions and frequent handling on construction sites.
• Hi-Vis: High-visibility finish enhances site safety and boundary awareness.
• Attachment: Designed to attach securely to temporary mesh fencing, enabling rapid deployment.
• Stability: Helps stabilise standard temporary fence panels, reducing movement in wind and minor impacts.
• Independently tested: Barrier performance and safety have been verified to support compliant site fencing.
• Panel compatibility: Two barriers required per panel, typically used with Heras panels for optimal stability.
• Installation guide: Slot Block Barrier Installation Guide available to download for reference and setup best practice.

Using two water-filled blocks per panel provides a solid, low-profile base that minimises trip hazards without adding significant height. The system supports safer perimeter management on construction sites, industrial yards, events, and other outdoor applications where temporary fencing is needed. Once deployed, these barriers offer practical ballast, clear visibility, and straightforward reconfiguration to adapt to site needs. For best results, follow the downloadable installation guide and consult site safety requirements to ensure compliant use.
