Sustainability,
honestly accounted for.
Concrete is carbon-intensive. We don't dress that up. What we do is hold to British and European standards, cut emissions where we can, and publish the work — finished and in progress.
How we think about it
Four things we hold to.
Concrete that lasts 50 years +
The most sustainable building is the one you don't have to rebuild. Properly specified precast carries a design life of 50 to 100 years. Most of what we cast outlives the original brief.
Local sourcing where we can
Aggregates from Devon and Cornwall quarries. Steel from UK suppliers. Drivers and fitters who live within an hour of the yard. Less haulage, less embodied carbon.
Co-located with renewable energy
Our Chilsworthy yard sits next to Severn Trent's anaerobic digestion plant. The infrastructure links are real and growing.
Honest about the journey
Concrete has a carbon problem. We're not pretending otherwise. We're cutting where we can — mix design, transport, energy — and we'll publish numbers as we have them.
Accreditations & standards
What we hold.
The British and European standards we conform to — covering product marking, concrete specification, structural design and panel manufacture. Plus manufacturer approvals from DeLaval and Lely for milking robot bases.
BSI Kitemark — ready-mixed concrete
CurrentReady-mixed concrete and aggregates are BSI Kitemark-certified to BS EN 206:2013+A2:2021 / BS 8500-2:2023. Mix designs documented and traceable, including sulphate-resisting and low-permeability variants.
BS EN 13369
CurrentCommon rules for precast concrete products — the factory production control framework WCCP manufactures under.
BS EN 14992
CurrentEuropean standard for precast concrete wall elements. Prestressed and reinforced wall panels manufactured to this standard.
BS EN 15037-1
CurrentPrecast concrete beams for beam-and-block floor systems, manufactured under factory production control.
BS EN 15258
CurrentPrecast concrete retaining wall elements. Covers king-post, L-shape and cantilever retaining systems.
BS EN 12737
CurrentPrecast concrete floor slats for livestock. Covers cattle slats manufactured to declared load classes.
BS EN 1992 (Eurocode 2)
CurrentDesign of concrete structures. Bespoke and structural elements designed and detailed to Eurocode 2.
Carbon
Numbers, not slogans.
We're working on Environmental Product Declarations (EPDs) for our flagship products and a published embodied-carbon figure (kgCO₂e/m³) for our standard mix designs.
When the figures are independently verified, they'll go on the site — not before. In the meantime, ask us at quote stage and we'll share what we have.
Coming soon
Carbon disclosure in preparation.
We're working on embodied CO₂e per m³ figures for our standard mixes — C32/40, C40/50, C40/50 SR and C50/60. When independently verified, they'll be published here.
- · kgCO₂e/m³ for standard mixes
- · Methodology: BS EN 15804+A2 (A1–A3)
- · Initiatives: GGBS, local aggregate, reduced transport miles
Co-location
Next door to the biogas plant.
Our Chilsworthy yard is built adjacent to the Holsworthy Biogas Plant, owned by Severn Trent Green Power — the FTSE-100 utility's renewable arm and one of the UK's largest food-waste AD sites. A circular-economy story on the doorstep: digestate one side of the fence, precast concrete the other.
Sitting next door is a deliberate choice. Heat, power and infrastructure links are part of the long-term plan. It's not a silver bullet for concrete's carbon footprint — but it's a sensible bit of joined-up thinking, and a story we're proud of.
Low-carbon spec
GGBS / CEM III/A mixes available on request — for architects and consulting engineers writing low-carbon specifications. Replacement of up to 50% Portland cement with ground granulated blast-furnace slag, designed to BS 8500-1:2023 with the same exposure-class compliance. Ask at quote stage.
What's next
Environmental Product Declarations.
EPDs are how architects and BREEAM assessors compare embodied carbon between manufacturers. We're working toward published declarations for our main product families — but we won't claim dates until we're confident in them.
In the meantime, if you need an indicative carbon figure for a specification, ask at quote stage and we'll share what we have.
Ask the awkward questions.
Specifying for a BREEAM project? Need a declaration of performance? Want the carbon figure on a panel? Ring up and ask.
