Concrete ballast block weighing 18.8kg designed to increase stability and wind resistance for temporary or semi-permanent fencing. Sized at 440mm x 215mm x 140mm, it fits seamlessly into ballast trays or base plates. Ideal for use with HERMEQ hoarding systems, this low-cost, easy-to-handle block delivers a reliable and tidy solution for site fencing stabilisation across construction and infrastructure projects.
Concrete ballast blocks provide the essential weight needed to stabilise temporary fencing and hoarding systems under high wind loads. Designed to work seamlessly with HERMEQ’s ballast trays and stabiliser systems, these 18.8kg blocks are used to secure steel hoarding panels and improve safety at active sites.
Their compact form factor (440mm x 215mm x 140mm) makes them ideal for use where space is limited but maximum ballast is needed. Unlike rubber blocks or sandbags, concrete blocks remain stable, tidy, and easy to count for compliance and site reporting.
- Increased Wind Resistance – Weigh down ballast trays and stabiliser systems to improve fence line strength.
- Steel Hoarding Compatible – Perfect for HERMEQ Safe Base Wind Systems and block tray stabilisers.
- Easy Handling – Size and weight balance makes them suitable for fast deployment and removal.
- Non-Spill Solution – Unlike bags of ballast, these maintain form without mess or leakage.
Concrete ballast is most often required when using solid hoarding panels due to their wind load. By contrast, mesh fencing typically requires lighter support. For demanding weather conditions or exposed locations, concrete blocks ensure long-lasting support. For best results, pair them with HERMEQ’s stabilisation kits, hoarding panel trays, or perimeter fencing anchor systems.
Whether securing roadside fencing or protecting public-facing developments, concrete ballast delivers cost-effective assurance that your fencing system will stay in place. Each block meets BS EN 771-3 standards and is suitable for repeated use.

Concrete ballast is relied on across all sectors where wind resistance and perimeter security must be guaranteed. Common deployment zones include:
- Urban Development Sites – Stabilise hoarding around city-based construction projects.
- Road & Rail Infrastructure – Secure perimeter fencing along highways or live transport zones.
- Events & Festivals – Anchor fencing around large crowds or wind-exposed zones.
- Retail & Utility Installations – Reinforce fencing during short-term fit-outs or utility maintenance.
HERMEQ ballast blocks are made from high-density concrete and offer an economical, practical alternative to more expensive rubber or water-filled ballast solutions. Designed for repeat use, their clean geometry and sturdy form make them ideal for both single and multi-site applications. Used in combination with stabilisers, these concrete blocks provide reliable ballast for both temporary and semi-permanent fencing structures.
