STEPOC

Designed to readily accept vertical and horizontal reinforcement; Stepoc is a system of concrete shuttering blocks that are highly-engineered and dimensionally coordinated.

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.

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. Anderton has a team of experienced personnel with a wealth of knowledge in the construction industry on hand to assist the customer. 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

FAQ's
Do you carry out the design of the Stepoc walls?

No, unfortunately Anderton Concrete does not offer this service. We can however carry out a take-off to determine the number of blocks required.

How often do I need movement joints in my wall?

We would suggest a maximum distance of 20m between movement joints but the final decision lies with the engineer designing the structure.

How much concrete do I need to fill my wall?

he following volumes of concrete are for guidance purposes – 200mm Stepoc 0.12m³/m², 256mm Stepoc 0.15m³/m², 325mm Stepoc 0.19m³/m²

What height can I build my wall before filling with concrete?

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.

How should the walls be filled?

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.

How many blocks are there per m² of wall?

There are 11.11 blocks per m² of wall for 200mm and 256mm Stepoc and 13.6798 blocks per m² for 325mm Stepoc.

How many blocks are in a pack?

Please refer to this page for further information www.andertonconcrete.co.uk/stepoc

Do the walls need to be propped prior to filling?

We would recommend that any free ends and corners are temporarily propped prior to filling.

Can I incorporate brick ties as I build the wall?

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.

Can I Install weep holes into my wall if required?

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.

Can I fix into the Stepoc wall?

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.

What method should I use for waterproofing the blocks?

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.

Does the block come with a finished face?

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.

What is the typical Lead time?

We can normally dispatch blocks within 1 week of an order being placed.

Can I construct non 90º corners with Stepoc?

Yes this is possible, please contact the Technical Department for further details.

Can I build curved walls with Stepoc?

Yes, it is possible to construct curved structures using Stepoc. Please contact the Technical Department for further details.

What is the Thermal Conductivity of Stepoc?

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)

When can I backfill behind the Stepoc wall?

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.

What types of delivery vehicles do you offer?

Please refer to the following guide

Do you have any stockists?

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.

Is there a minimum order quantity?

No
