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 BS EN 1992-1-1 (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. Lead time 2-6 weeks; bespoke heights and 120-year design lives priced individually. Includes the named WCCP Rapid Fit Retaining Wall System.
- · Heights 1m–6m (3'3"–19'8")
- · Up to 60 kN/m²
- · Eurocode 2 design
- · 50-year design life
- · Four systems
- · 2–6 week lead

Four ways to retain ground.
Same yard, same paperwork — different shapes for different jobs. Click through to the system page for full specs.
King Post Walls
UB/UC posts · panel infill
Fast-build retaining using prestressed panels slotted between steel king posts. Heights 1m to 6m.
L-Block Retaining
1m–6m · interlocking
L-shaped precast blocks for silage, grain and bulk storage bays. Stack like Lego, no foundation needed.
Cantilever Walls
Free-standing · 50-yr life
Engineered free-standing cantilever walls to BS EN 1992-1-1. Heavy civils retention.
Prestressed Panels
BS EN 14992
Catalogue panels for any of the three systems above, or for direct fix to existing structures.
Named system
Rapid Fit Retaining Wall System™
WCCP's named retaining-wall system. A 900 × 1500mm (2'11" × 4'11") face on a 1200mm (3'11") depth at 2,120kg (4,670 lb) per unit, with 'L' shaped top units available at 885kg (1,950 lb).
The unit shape permits both convex and concave wall faces — a single system cope with curved retention runs, civils retention bends and the gentle sweeps that L-blocks and cantilever panels can't follow. Engineered to BS EN 1992-1-1 with 50-year design life.

Heights, surcharge and foundations.
Indicative ratings across the four systems. Site-specific design always carried out to BS EN 1992-1-1.
| 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 | 1.0–6.0m (3ft3in–19ft8in) | 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 |

Common questions
What people ask about retaining walls.
Five questions we answer most weeks. If yours is not here, ring the yard.
Which retaining system do I want? +
For agricultural bay storage, L-blocks every time — quick to set, no footing. For civils retention up to 6m with surcharge, king post is usually the cheapest. For free-standing engineered retention to road or rail loadings, cantilever. We will design the cheapest right answer for your loadings — send us the section and we will spec it.
What heights can you go to? +
All three systems run from 1m (3ft 3in) up to 6m (19ft 8in) as catalogue. Above 6m we get into bespoke engineering and tied-back solutions — talk to the yard.
What surcharge ratings do you support? +
Up to 60 kN/m² on king-post systems with the right post and footing, 50 kN/m² on cantilever, 30 kN/m² on free-standing L-blocks. Site-specific design always to BS EN 1992-1-1.
Do you do the install? +
King post and cantilever installs we project-manage end to end. L-blocks are designed for the customer's teleporter or loader. We supply the install drawing, the bedding spec and the lift points either way.
How are designs signed off? +
Every wall is designed to BS EN 1992-1-1 (Eurocode 2) and manufactured to BS EN 14992 / BS EN 13369, with a designer's sign-off; structural calcs and conformity documentation are available on request. For grant-funded jobs we supply the SSAFO 2018 paperwork too where slurry contact is involved.
