Grundon Sand & Gravel

What Grundon Sand & Gravel does

Grundon Sand & Gravel Limited is a family-owned UK aggregates producer operating four quarries across Southern England — Faringdon (Oxfordshire), Frith End (Hampshire), Kennetholme (Berkshire), and New Barn Farm (Oxfordshire) — extracting and processing sand, gravel, clay, decorative stone, and soil products for the building, construction, landscaping, golf/equestrian/leisure, and DIY markets. The company was founded in 1929 by Stephen Grundon, has remained under family ownership across three generations (Norman Grundon as President/Chairman, Neil Grundon as Deputy Chairman), and is registered in England as Company No. 443147 with its registered office in Benson, Wallingford.

The core technology is physical mineral extraction, washing, and grading, with two proprietary product lines underpinning differentiation: the Coxwell range (Self-Binding Path Gravel, Pathway Sub-Base, Rockery Stone, Gabion Stone, Drainage Stone) sourced exclusively from a prehistoric dolomitic limestone deposit at Faringdon, and the Golden Harvest Gravel exclusive to New Barn Farm. The company holds PRIME (Professional Recognition in Mineral Extraction) status from the Institute of Quarrying across its active extraction sites, CE Declaration of Conformity for all products, and Living Wage Foundation employer accreditation. Recently added to the range are recycled aggregates and carbon-negative aggregates, leveraging the 90%-owned O.C.O Technology subsidiary and its Accelerated Carbonation Technology.

Commercial operations run on a transactional one-time-sale model at unit prices of roughly £66 to £103 per 850 kg bulk bag (excluding delivery and VAT), distributed through two channels: direct quarry weighbridge sales under an 'open-door' policy that serves general public, small builders, landscapers, and DIY customers with no minimum order, and an e-commerce platform offering nationwide pallet delivery. Customer segments span construction trade, landscape architects, golf courses, equestrian facilities, children's play providers, and individual consumers. Sales office hours are Monday–Friday 8:00–16:30. The 11-50 employee operation is led by CEO Clayton Sullivan-Webb alongside seven other directors, with Toni Robinson appointed as the first female board member and Risk & Sustainability Director in August 2024.
