Slurry Storage.
SSAFO 2018-ready. Six-month capacity.
Precast slurry walls are SSAFO 2018-compliant, 95mm to 180mm thick (4in to 7in) at heights of 1.0m to 1.5m (3'3" to 4'11"), designed to Eurocode 2, with sulphate-resisting C40 up to C60 concrete.
WCCP precast slurry store walls are 95 mm, 145 mm or 180 mm (4in, 6in or 7in) thick, with the 180 mm panel able to stand in cantilever without posts, to the retained height your engineer specifies. Walls must be impermeable (k ≤ 1×10⁻⁹ m/s).
SSAFO 2018-compliant precast slurry storage. WCCP prestressed panels at 95mm, 145mm or 180mm (4in, 6in or 7in) thick at heights of 1.0m, 1.2m and 1.5m (3'3", 3'11" and 4'11"), with custom or 15' and 20' standard lengths. The 180mm Vertical Cantilever Panels can stand without supporting posts, to the retained height your engineer specifies. Mix matched to the exposure on the drawing.

| Thickness | Heights available | Lengths | Typical use |
|---|---|---|---|
| 95mm (4in) | 1.0m (3ft3in), 1.2m (3ft11in), 1.5m (4ft11in) | Custom + 15' & 20' standard | Bund walls, transition panels, lower-load applications |

Vertical Cantilever Panels
No supporting posts required.
The 180mm panels retain to the heights below in cantilever — no supporting posts in the wall run. 145mm panels can be used in cantilever with retained heights reduced by 0.3–0.4m (1ft–1ft4in).
| Service | Retained height (180mm) | Notes |
|---|---|---|
| Slurry retention | To your engineer's design | Tell us the retained depth and panel thickness specified |
| Silage with vehicle surcharge | To your engineer's design | Surcharge from the vehicles that will run against it |
| Earth retention | To your engineer's design | Retained height and surcharge from the section drawing |

Common questions
What do buyers ask about slurry storage?
Are your slurry products SSAFO 2018-compliant?
Yes. All our slurry storage panels meet The Water Resources (Control of Pollution) (Silage, Slurry and Agricultural Fuel Oil) (England) Regulations 2010 as amended in 2018. Designed for 6-month minimum storage capacity, watertight joints, and compliant freeboard.
How much slurry storage do I need?
For SSAFO compliance you need a minimum 6 months. For a 200-cow dairy herd that's typically 2,500-3,000m³. We'll size it from your herd numbers, housing system and rainfall catchment. Use our slurry calculator on the slurry-storage product page.
What's the difference between prestressed and reinforced?
Reinforced concrete uses passive steel bars to handle tension. Prestressed concrete uses high-tensile strands tensioned before the concrete cures, putting the panel into permanent compression. The result: thinner, stronger, longer-spanning panels with far better crack resistance — particularly important for slurry and silage applications.
What thicknesses are prestressed panels available in?
Prestressed wall panels are stocked in six thicknesses (95, 120, 145, 180, 230 and 280mm), five widths from 500mm to 1500mm (the panel's installed height) and two lengths, 15ft (4572mm) and 20ft (6096mm). Custom lengths to 6500mm and bespoke details are cast to order.
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.

Sizing tool
How much slurry storage do you need?
Plug in herd size, animal type and storage months — we will translate it into an SSAFO-compliant volume, the WCCP panel system that fits, and a panel-count estimate. All compute is on this page; nothing leaves your browser.
Indicative only. Final design is site-specific to Eurocode 2 with surcharge, freeboard and SSAFO 2018 capacity statement issued in the order pack.
