STEPOC
Designed to readily accept vertical and horizontal reinforcement; the Stepoc retaining wall is a system of concrete shuttering blocks that are highly-engineered and dimensionally coordinated.
Stepoc Calculators
Our Stepoc Calculators allow you to quickly determine the quantity of blocks required to construct your project – just select the appropriate block thickness and enter your details.
Stepoc is filled with concrete, which is pumped down through the inter-connected cavities in the blocks. The blocks unique design creates a cascade or waterfall effect which ensures a smooth filling of the pumped concrete, forcing out air and eliminating segregation, to create walls which have immense compressive and lateral strength.
What is Stepoc?
Stepoc is a precast concrete block retaining wall system that can be laid dry. Stepoc blocks are hollow which allows for reinforcement bars to be inserted and for concrete to be pumped down through the inter-connected cavities in the blocks.

The Benefits of Stepoc
Anderton’s precast retaining walls are a great alternative to shuttered and poured concrete.
Stepoc enables the fast construction of single skin retaining walls up to 4.0 metres high, subject to a design carried out by a structural engineer. It can be filled in a single pour from 1.8-2.25m depending on block thickness. Stepoc is available in three widths, 200, 256 and 325mm and at less than 20kg per unit.
Stepoc is proven in use on applications the length and breadth of the UK with a huge growth in sales over recent years proving its suitability and popularity. From basement walls and swimming pools, to flood defences and blast panels, Stepoc can be used in almost any applications.
Anderton has a team of experienced personnel with a wealth of knowledge in the construction industry on hand to assist you with your project requirements. Stepoc combines the ease of blockwork construction with the versatility of in-situ concrete, and yet is faster to apply than both.
Examples of Construction using Stepoc:
- Retaining Walls
- Basement Walls
- Flood alleviation schemes
- Swimming Pools
- Blast Panels
- Lift Shafts
- Platform Edges

No, unfortunately Anderton Concrete does not offer this service. We can however carry out a take-off to determine the number of blocks required. https://www.andertonconcrete.co.uk/about-us/
We would suggest a maximum distance of 20m between movement joints but the final decision lies with the engineer designing the structure.
he following volumes of concrete are for guidance purposes – 200mm Stepoc 0.12m³/m², 256mm Stepoc 0.15m³/m², 325mm Stepoc 0.19m³/m²
We would recommend a maximum of 8 courses for 200mm Stepoc and 10 courses for 256mm and 325mm Stepoc, however final pour height will be determined by the construction sequence on site.
We would recommend the use of a concrete pump; however in restricted situations the use of other methods can be employed. It is important to use a fluid concrete mix with a minimum 150mm slump to allow the concrete to flow through the blocks.
There are 11.11 blocks per m² of wall for 200mm and 256mm Stepoc and 13.6798 blocks per m² for 325mm Stepoc.
Please refer to the Anderton Brochure (page 54) for further information
We would recommend that any free ends and corners are temporarily propped prior to filling.
Yes, standard brick ties can be built into the Stepoc walls as they are constructed as the block height of 225mm coordinates with traditional brick and block coursing.
Yes, we would recommend this is carried out prior to filling the wall with a hole being cut through the blocks and PVC pipe or other preparatory system being employed.
Yes, We would recommend speaking to a fixing specialist who will be able to determine the correct type of fixing for your particular situation and loading.
We would always recommend speaking with a waterproofing specialist prior to undertaking any product application and also ensure that the method meets the guidelines set out by the NHBC or other warranty provider where applicable.
The face of Stepoc is quite close textured and can be left unfinished, however in the majority of situations an additional finishing layer would be normal practice.
We can normally dispatch blocks within 1 week of an order being placed.
Yes this is possible, please contact the Technical Department for further details.
Yes, it is possible to construct curved structures using Stepoc. Please contact the Technical Department for further details.
The wall once in-filled with concrete will provide a Thermal Conductivity (k value) of 1.60 W.m-1.K-1) (figure taken from CIBSE guide)
We would recommend that backfilling takes place approximately 7 days after the concrete has been poured but the final decision lies with the engineer designing the scheme.
Please refer to the Transport Options guide for further information.
Yes, we have a number of stockists that hold blocks on the ground for immediate order and delivery. Please call the Sales Office for further information.
