Our Faringdon quarry, in South Oxfordshire, is the home of our exclusive range of Coxwell stone products, which include the popular Coxwell Self-Binding Path Gravel, path dressing, rockery stone and boulders. The Coxwell products are produced from a totally unique dolomitic limestone sponge gravel which were formed in what was once a prehistoric tropical lagoon at the site of our Faringdon quarry. The Coxwell range of products are only available through Grundon.
