Interlocking tongue & groove blocks for fast, straight runs
The 3m concrete hoarding block creates a stable, continuous base for hoarding systems. With an interlocking tongue and groove design, the blocks align securely, giving you a neat, straight line that also provides added protection for pedestrians.
At just 450mm wide, these blocks maintain a minimal footprint, making them ideal for city-centre projects, pedestrian zones, and construction sites where space is limited. They’re compatible with timber hoarding, steel panels, and reusable PVC systems, giving you flexibility to choose the hoarding type that best suits your project.
Product Features & Specifications of Hoarding Blocks
Our 3m concrete hoarding blocks are built for stability, flexibility, and long service life.
Concrete strength: C40 mix
Made with a strong C40 concrete mix, providing strength and durability for both temporary and long-term hoarding projects.
Connection: tongue and groove interlock
Interlocking design keeps the line straight, reduces movement, and offers added security compared to standalone ballast blocks.
Edge detail: chamfered edges
Chamfered edges prevent damage and help the blocks maintain a clean finish when installed in visible locations.
Concrete finish: mould finish on visible faces
Cast to a high-quality finish on visible faces, making them ideal for public-facing environments such as city centre projects.

“JP Concrete were as reliable in delivery as they were throughout the rest of our dealings with them. They manufactured over 140 blocks within a tight timeframe and organised staggered deliveries which were all on time. They also collected the blocks from the bridge, which presented its own issues, but again these were worked around with the minimal amount of fuss.”
