Feed-Stop Walling.
Steel where it scrapes. Concrete where it sits.
3m precast feed-stop wall units with a galvanised steel lip cast into the top edge — the part the tractor bucket scrapes against every feeding round. Cast in sulphate-resisting C40/50 concrete to BS 8500-1:2023. SSAFO 2018-compliant. Catalogue lead time 2-4 weeks.
A feed-stop wall is the upright concrete face of a silage clamp — the part the loader bucket scrapes when taking the next feed cut. WCCP feed-stops cast a 6 mm × 100 mm (¼in × 4in) galvanised steel lip into the top edge so the wear hits the steel, not the concrete. Design life 25+ years versus 8 for bare concrete.
We cast, deliver and install across England and Wales — the right answer for new silage clamps, AD feedstock storage, and SSAFO 2018 refurb work.

Specification
Heights, lengths and lip detail.
Catalogue 3m units in three standard heights. Bespoke corners, taller faces and AD feedstock walls quoted on application.
| Variant | Dimensions | Detail | Typical use |
|---|---|---|---|
| Standard Feed-Stop 3m × 1.2m | 3000 × 1200 × 200mm (9'10" × 3'11" × 8in) | Galvanised steel lip cast in | Silage clamp face — dairy and beef |
| Tall Feed-Stop 3m × 1.5m | 3000 × 1500 × 200mm (9'10" × 4'11" × 8in) | Galvanised steel lip cast in | Deep clamp face / maize silage |
| Short Feed-Stop 3m × 0.9m | 3000 × 900 × 200mm (9'10" × 2'11" × 8in) | Galvanised steel lip cast in | Smaller clamps / wholecrop |
| Corner Feed-Stop | Bespoke L-profile | Mitred junction · steel lip continuous | Clamp ends and L-junctions |
| Tractor-Bucket Wear Plate | Galv. lip section only | Bolted-on retrofit lip | Refurbishing existing concrete walls |
The galvanised steel lip is hot-dip to BS EN ISO 1461 — typically 85 microns coating — cast in with shear studs at 300mm (1ft) centres for permanent bond to the concrete.

Where they go
Common applications.
From a 1500-tonne dairy clamp in Devon to a 6000-tonne AD feedstock store in the Midlands, the feed-stop unit is the same — it is the lip that earns its keep.

Common questions
What people ask about feed-stop walling.
Five questions we answer most weeks. If yours is not here, ring the yard.
What is the steel lip for? +
Silage clamp faces are abused. Every day a tractor bucket scrapes the top of the wall taking the next feed cut. Without a steel lip the concrete chips, then crumbles, and within five years you have a half-rotten wall. The galvanised lip — typically 6mm (about ¼ inch) thick, 100mm (4 inches) tall — takes the wear and saves the concrete underneath. WCCP feed-stop walls last 25+ years where bare concrete walls last 8.
What concrete spec do you use? +
Sulphate-resisting C40/50 to BS 8500-1:2023. Silage effluent is acidic — pH 3.5 to 4.5 — and standard concrete dissolves in it. The sulphate-resisting mix plus a 50mm (2 inch) cover to the steel gives a design life of 50+ years for the buried portion.
Free-standing or anchored? +
Both. Standard 3m units are free-standing on a 600mm × 200mm (2ft × 8in) reinforced strip foundation, locked together with cast-in dowel bars. For taller clamps and AD feedstock walls we anchor to a continuous toe slab. Either way the design is signed off by our consulting engineer.
How are they delivered? +
On our HIAB lorry — a 3m × 1.2m (9'10" × 3'11") unit weighs about 1.7 tonnes (roughly 3,750 lb), so we lift straight off onto the prepared base. We deliver UK-wide; site access for an articulated HIAB needs about 4m (13'1") clear width and a hard standing within 12m (39'4") of the wall line.
What is the lead time? +
Catalogue 3m feed-stop units run 2 to 4 weeks. Bespoke heights and corner pieces 4 to 6 weeks. Major SSAFO 2018 refurbs with engineering design run 6 to 10 weeks for the design-and-cast cycle.
