Retaining Walls.
Engineered to Eurocode 2. Cast in North Devon.
What's the difference between a retaining wall and a king post wall?
What's the difference between a retaining wall and a king post wall? "Retaining wall" is the family — any structure holding back earth. A king post wall is one type, with steel UC posts in piles and precast infill panels. Cantilever, L-block and gravity walls are other types in the same family. WCCP supplies all four.
Precast retaining walls 1.0m to 6.0m high (3'3" to 19'8"), designed to Eurocode 2. King-post systems handle up to 60 kN/m² surcharge, cantilever 50 kN/m², L-block 30 kN/m², panel-and-post 40 kN/m². Foundations vary by system. Bespoke heights priced individually — please call to check current yard stock or current lead times.
- · Heights 1m–6m (3'3"–19'8")
- · Up to 60 kN/m²
- · Eurocode 2 design

Same yard, same paperwork — different shapes for different jobs. Click through to the system page for full specifications.
King Post Walls
UB/UC posts · panel infill
Retaining using prestressed panels slotted between steel king posts. Heights 1m to 6m.
L-Block Retaining
2.5m–4m · free-standing
'A', 'L' and 'T' precast wall sections, plus Interlocking Beton Blocks, for silage, grain and bulk storage bays.
Cantilever Walls
Free-standing · no tie-back
Free-standing cantilever units, manufactured in compliance with applicable British Standards. Heavy civils retention.
Prestressed Panels
Precast wall panels
Catalogue panels for any of the three systems above, or for direct fix to existing structures.

Heights, surcharge and foundations.
Indicative ratings across the four systems. Site-specific design always carried out to Eurocode 2.
| System | Height range | Max surcharge | Foundation | Typical use |
|---|---|---|---|---|
| King Post | 1.0–6.0m (3ft3in–19ft8in) | Up to 60 kN/m² | Strip + post pockets | Civils, road schemes, basement props |
| L-Block | 2.5–4.0m (8ft2in–13ft1in) | Up to 30 kN/m² | Compacted hardcore | Silage, grain, aggregate, biomass bays |
| Cantilever | 1.5–6.0m (4ft11in–19ft8in) | Up to 50 kN/m² | Cast-in-situ heel | Free-standing civils retention |
| Panel + post | 1.0–4.5m (3ft3in–14ft9in) | Up to 40 kN/m² | Strip + UB/UC posts | Boundary walls, push walls |

Standards & certification
Engineered to current code.
Our products are manufactured in compliance with applicable British Standards. Structural design is carried out to Eurocode 2 by your engineer; we supply to their design. For information regarding the specific standards applicable to a particular product, please contact us.

Common questions
What do buyers ask about retaining walls?
Do you design retaining walls?
Yes — King Post, L-Block and cantilever units are manufactured in compliance with applicable British Standards, under factory production control. Tell us the retained height and surcharge your engineer has specified and we'll come back with the units to suit and a casting drawing. We are a manufacturer, not a design practice: the wall design and any signed structural calculations come from your own engineer.
What concrete grade do you use?
Standard mix is C40/50 sulphate-resisting with CEM III/A cement (around 50% GGBS) for slurry and cubicles, with silage clamp walls at C50/60 sulphate-resisting, cast with a DC-3 or DC-4 designation where the ground or exposure class calls for it. Lightly reinforced items such as padstones use C40/50 (50 N/mm² at 28 days, CEM I); prestressed panels and robot bases use C50/60 high-strength. A C40/50 low-carbon mix with CEM III/B (around 70% GGBS) is available for retaining walls. Bespoke mixes available on request.
Are your products CE / UKCA marked?
Our products are manufactured in compliance with applicable British Standards, under factory production control. For information regarding the specific standards applicable to a particular product, please contact us. CE/UKCA marking and Declaration of Performance status vary by product — ask the office to confirm exactly what applies to your order before you rely on it for a compliance submission.
Can you provide drawings or CAD blocks?
Yes — PDF data sheets and 2D .dwg blocks for AutoCAD, from our /downloads page. We do not publish BIM models or parametric Revit (.rfa) families. Most of our CAD work is in SketchUp, and for a specific job we can sometimes export an IFC that Revit will read — ring the office and ask rather than expecting a download.
Do you offer installation?
No — we manufacture and supply only. We don't have an install team and we don't fit, erect or build in anything we make, on any product line. Installation is down to your groundworker or civils contractor. What we will do is give them what they need to get it right first time: setting-out drawings, lifting anchor positions and fixing details, plus a phone call with the yard if they want to talk it through before the load arrives.
