Stepoc is a system of highly-engineered and dimensionally co-ordinated building modules which are designed to easily accept horizontal reinforcement for use where structural performance is the prime consideration.

Stepoc combines the ease of blockwork construction with the versatility of in situ concrete, and yet is faster to apply than both, making it an ideal component for:

• Retaining walls
• Sheer wall
• Laterally-loaded panels
• Blast panels
• Bund walls
• Basement walls
• Swimming pools

It is also suited to any applications that require higher compressive or lateral loads than those achievable with standard masonry. The Stepoc system is available in three widths of 200mm, 256mm and 325mm and each comprises a range of units allowing the construction of terminal ends and corners while still achieving the correct bond.


Built dry, with no mortar joint, and requiring no special on site skills or techniques, the blocks are laid to a running bond, using a combination of half or third and full length blocks. Specific data sheets are available to illustrate the construction of ends, corners and other required details.

Stepoc's unique design enables horizontal reinforcement to be placed adjacent to either block face, or both if required, to ensure that maximum strength is achieved just where it's needed.

Stepoc is bonded with concrete, which is poured down through the interconnected cavities in the blocks. The block's unique design creates a cascade or waterfall effect which ensures a smooth filling of the poured concrete, forcing out air and eliminating segregation, to create walls which have immense compressive and lateral strength.

Stepoc enables the fast construction of single skin retaining walls up to 3.8 metres high, subject to a design carried out by a structural engineer.

At less than 20kg all units are well within the Health and Safety Executive guidelines for a single man repetitive lift. Stepoc is proven in use on applications the length and breadth of the UK.
