Our quarries are the backbone of everything we produce — from premium washed building sands to high-performance crushed rock, ready-mix concrete, and specialist aggregates. By managing extraction, processing, and delivery in-house, we ensure quality, consistency, and dependable supply across all orders.
Cowbog is the heart of the business and where it all started 85 years ago. Home to our administrative HQ, concrete block manufacturing, and bagged aggregate line, it’s also the main public collection point for smaller-scale orders, trade customers, and DIY projects.
What’s here:
Blackhills is home to our high-quality washed building sand and specialist sands. Using a state-of-the-art hydro-cyclone washing plant, we produce clean, consistent material trusted by builders, architects, and landscapers for structural, decorative, and finishing applications.
Perfect for:
Cottonhill produces the crushed rock aggregates used in road construction, drainage, groundworks, and civil engineering. Blasting and on-site crushing allow us to supply durable, high-performance materials including Type 1, Type 2, Type 3, single sizes, hardcore, and armour stone.
