Space-saving hoarding with quick-fit fixings

Each block features a fork recess in the base for easy handling and precast through-holes for securing with scaffold poles. Optional threaded sockets allow you to bolt on steel brackets for posts – no drilling or resin anchors required.

Product Features & Specifications of Hoarding Blocks

Our 850kg concrete hoarding blocks are designed for durability, flexibility, and safe handling. Here’s what sets them apart. 

Concrete strength: C40 mix

Manufactured with a high-strength mix for reliable performance through repeated uses. 

 

Connection: flat edges (non-interlocking)

Flat-sided blocks for easy placement and alignment. 

Edge detail: chamfered edges

Chamfers reduce visible chipping and keep edges neat on public-facing sites. 

 

Concrete finish: mould finish on visible faces

Smooth mould finish for a professional appearance; non-visible faces are hand-trowelled. 

Design life:  50 years+

Built for a long service life, reusable in multiple projects. 

 

Reinforcement cover: N/A (unreinforced)

No steel means no risk of corrosion; blocks can be crushed and recycled at the end of their life.
