RTC Quarries

RTC Quarries: natural slate from Cornwall and Devon

RTC Quarries Ltd. is a British company dedicated to the extraction and sale of natural slate, operating in Cornwall and Devon. The company presents itself as a supplier of ethically quarried stone and plant hire services, serving both private customers and trade professionals.

Three working quarries

The company operates three distinct quarries:

• Trebarwith Road, in Delabole, linked to the internationally renowned Delabole slate.
• Trevillett, located in the parish of Tintagel, in Rocky Valley.
• Mill Hill, in Tavistock, with over 400 years of operation according to the company itself.

Product catalogue

The catalogue is organised into several lines of natural stone and complementary materials:

• Facing stone, to clad facades and enhance the appearance of properties.
• Walling stone, designed for durable structures in the landscape.
• Hedging stone, intended specifically for dry stone walls.
• Roofing slate, quarried, sawn and split in Cornwall.
• Paving stone, natural west country slate for gardens.
• Rockery & feature slate rocks, for gardens.
• Aggregates, with recycled stone materials.

Extraction and preparation process

The company describes a three-stage process: mechanical extraction of the stone from the quarry face, screening and sorting into designated product lines, and loading and preparation for transport to its destination. The company states that respect for the environment is present throughout the process.

Delivery and logistics

According to the information published, most materials are delivered loose, although some are palletised and others can be supplied bagged if requested. The company asks the customer about site access before delivery, as not all vehicles are suitable for every location. The transport methods it uses include vehicles with Moffett all-terrain forklifts, tipper lorries, Hiab crane lorries and flatbed lorries.

Frequently asked questions about the product

The website covers several common questions. On coverage per tonne, the company warns that the figures are approximate, that wastage must be allowed for and that each product has a different coverage, so it recommends asking for advice. Regarding colour, it points out that slate is a natural product and does not guarantee uniform tones: once extracted, exposure to the environment causes natural oxidation and rustic and sandy hues may appear. It also indicates that it is possible to buy small quantities, paying only for what is taken away, and that lead times depend on seasonal demand and conditions at the quarry itself.

Customer profile and complementary services

The company states that it serves the local area and customers further afield, and offers additional technical information to trade professionals. In addition to stone, it provides plant hire services.
