The questions we get asked most.
Answered plainly.

Everything that leaves the yard is made under factory production control. Our products are manufactured in compliance with applicable British Standards. For information regarding the specific standards applicable to a particular product, please contact us. Product conformity documentation is available on request.

Standard mix is C40/50 sulphate-resisting with CEM III/A cement (around 50% GGBS) for slurry, silage clamps and cubicles, 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.

Standard prestressed wall panels come in 95mm, 145mm and 180mm thicknesses, in widths from 1.0m to 2.5m. Bespoke sizing available.

Yes. We draw, mould and cast one-offs all the time — from architectural copings to non-standard culvert sections. Send a sketch or DWG and we'll come back with feasibility, cost and a lead time.

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.

Two things: sulphate attack (handled by mix design) and impact damage (handled by panel thickness and reinforcement). Both are addressed at the specification stage to suit the exposure class.

Concrete is non-combustible — as a material it is classified Euroclass A1 without further testing. Fire-resistance performance (the REI classification) is not a property of concrete in general: it depends on the individual unit's thickness, axis distance to the reinforcement, support conditions and load level. Tell us the fire rating your building control or insurer requires and we will confirm the panel specification needed to meet it.

Yes — concrete takes paint, render, timber cladding or stone facing readily. We can supply panels with a smooth as-cast finish, a textured finish, or pre-drilled fixings for cladding battens. Specify at order.

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.

Standard sizes: Holstein-Friesian — 2.4m × 1.2m. Jersey — 2.2m × 1.1m. Beef sucklers — 2.3–2.5m × 1.15–1.25m depending on frame (Continental breeds at the top of the range). Heifers — 2.2m × 1.1m. Custom sizes for crossbreeds or unusual herds available — send us your average mature cow weight. Full breakdown in our cubicle sizing guide.

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.

Yes — bespoke pre-cast bases for DeLaval VMS, Lely Astronaut and similar robot systems. Cast with the right falls, drainage, cable ducts and bolt-down points. Please call to check current lead times from drawing approval.

Start with tonnage required, then density (we use 700kg/m³ wilted grass), then divide by usable height (typically 3m). We use C40/50 sulphate-resisting concrete with effluent channels and non-slip aprons. We'll do the design with you — bring rough dimensions and intended throughput.

Our feed troughs come with cast-in fixings for bolting to a slab, or as freestanding units with footplates. For new builds we recommend cast-in bolt boxes set into the slab pour. We can supply a setting-out drawing.

Yes — a two-part kit in total lengths of 2.5m, 3m, 3.5m or 4m. Overall width 1300mm, overall height 875mm, with a narrower 600mm internal base to save chemical on every fill, 300mm entry and exit stepover walls and four corner drain holes. Lifting loops, sealant and applicator gun come with the kit.

We size cubicles and lying surfaces from AHDB Dairy guidance, and we can cast to whatever dimensions your assurance scheme requires. Tell us which scheme you are audited under and the standard you are working to, and we will confirm the dimensions at quote stage.

We started casting in 1973 — that's over 50 years of precast in North Devon. A family-led business under sole ownership since 2009, now in a purpose-built yard near Holsworthy (since 2023).

Off Andigestion Lane, Chilsworthy, Holsworthy, Devon EX22 7HH. Beside the Severn Trent biogas plant. Visitors welcome by appointment.

Yes — public liability and employers' liability at £10m each, plus product liability. Certificates available on request before any contract.

Yes — independent and privately owned, not part of a national group. Ownership sits with the managing director rather than a plc board.

Devon, Cornwall, Somerset, Dorset and Wiltshire are our home turf. Beyond that we deliver UK-wide on planned runs — England, Wales, Scotland and Northern Ireland — and into Germany, the Netherlands, France and Belgium when European jobs come up. If you're willing to pay the carriage we're willing to load the wagon.
