Silage Clamp Walls.
Acid-tight. Push-rated. Stack and seal.
What are precast silage clamp walls?
Precast prestressed silage clamp panels at heights of 1.0, 1.2 and 1.5 m (3'3", 3'11" and 4'11"), cast in sulphate-resisting C50/60 concrete (CEM III/A) to BS 8500-1:2023 exposure designed to Eurocode 2. Acid-resistant for grass, maize and wholecrop silage; vertical cantilever to your engineer’s retained height with no supporting posts. FETF-eligible variants available — please call to check current yard stock or current lead times.
WCCP prestressed clamp panels. Heights of 1.0m, 1.2m and 1.5m (3'3", 3'11" and 4'11") at thicknesses of 95mm, 145mm or 180mm (4in, 6in or 7in). Custom lengths to order plus 15' and 20' standard stocked lengths. The 180mm Vertical Cantilever Panels can stand without supporting posts, to the retained height and surcharge your engineer specifies.

Prestressed Panels
Three thicknesses, three heights.
95mm, 145mm or 180mm thick (4in, 6in or 7in) at 1.0m, 1.2m and 1.5m heights (3'3", 3'11" and 4'11"). Custom lengths to order, plus 15' and 20' standard stocked lengths.
| Thickness | Heights available | Lengths | Typical use |
|---|---|---|---|
| 95mm (4in) | 1.0m (3ft3in), 1.2m (3ft11in), 1.5m (4ft11in) | Custom + 15' & 20' standard stocked | Lighter clamp side walls and bay divisions |
| 145mm (6in) | 1.0m (3ft3in), 1.2m (3ft11in), 1.5m (4ft11in) | Custom + 15' & 20' standard stocked | Mid-size clamps; cantilever heights reduced 0.3–0.4m (1ft–1ft4in) vs 180mm |
| 180mm (7in) | 1.0m (3ft3in), 1.2m (3ft11in), 1.5m (4ft11in) | Custom + 15' & 20' standard stocked | Standard clamp panels; vertical cantilever rated |
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 filling vehicle |
| Earth retention | To your engineer's design | Retained height from the section drawing |
