What Capital Concrete Ltd does

Capital Concrete Ltd is a London-based ready-mix concrete and flowing screed supplier operating ten batching plants across Greater London and Southeast England, with flagship capacity of 300 m³/hr at its Wembley plant (which features a dedicated rail siding) and additional capacity at Silvertown (200 m³/hr), Cricklewood (160 m³/hr), Staines (100 m³/hr), Rainham (80 m³/hr), Croydon (70 m³/hr) and Bow, Enfield, Langley and Romford (50-60 m³/hr each). The portfolio spans standard mixes plus specialty products including waterproof, steel-fibre and polypropylene, self-compacting, slipform, high-rise (grades up to C100/105), lightweight (1,550-2,000 kg/m³), heavyweight (2,400-4,200 kg/m³ using barytes/magnetite), coloured and extended-open-life concrete, alongside Gyvlon anhydrite and Cemfloor cement-based flowing screeds. Differentiated low-carbon offerings include the exclusively London-licensed Earth Friendly Concrete geopolymer (up to 87% embodied carbon reduction), Ecocem ACT low-clinker cement (up to 70% reduction) developed via consortium with BRE Group, Creagh Concrete, Loughborough University, Ramboll Group and Sisk, CarbonCAP, CarbonCure, and the UK's first calcined clay concrete residential deployment at Brent Cross Town using LKAB Minerals' recycled-brick-derived calcined clay.

The company is a wholly-owned subsidiary of Brett Group, a diversified UK construction materials conglomerate, with headquarters in Maidstone, Kent and serves two customer segments: commercial construction firms and main contractors (its primary segment, supplying Crossrail, Thames Tideway Tunnel, Northern Line Extension, Battersea Power Station, The Shard, Wembley Stadium, the 2012 Olympic venues, Westfield Stratford, and sole-supplying HS2's Central Section in London) and domestic/homeowner customers via phone, email and a website contact form supported by a concrete quantity calculator. Sales are direct (no channel intermediaries) with project-tendered pricing and same-day order placement, and the senior team averaging 30+ years of London ready-mix experience anchors a reputation-driven book of repeat business among London main contractors.

Pricing is not publicly disclosed and follows a project-based quote model; revenue is generated through one-time sales of ready-mix concrete batches delivered via the company-owned fleet to construction sites within roughly an hour's drive from each batching plant, with the headquarters routed through Eclipse House, Eclipse Park, Sittingbourne Road, Maidstone, Kent ME14 3EN.
