Established in 1987 as DMC Quarries, the business specialised in supplying coloured stone to architectural, landscaping and concrete markets across Australia. With a clear focus on quality, reliability and service, DMC supported regional infrastructure and construction projects by providing trusted aggregate solutions. In 2019, DMC was acquired by SEE Group, a proud family-built organisation with a similarly strong reputation across the civil and mining sectors. Values of hard work, long-term thinking and commitment to excellence underpinned both businesses from the very beginning.
In 2026, SEE Group rebranded DMC Quarries to Specialised Aggregates. With SEE Group’s depth of capability, investment and operational expertise, Specialised Aggregates is positioned to grow while maintaining the hands-on approach and local knowledge that has always defined the operation. The transition reflects both continuity and progress: respecting the legacy of the past while embracing new opportunities for innovation, safety and sustainable growth. Specialised Aggregates is focused on supplying high-quality materials, supporting local communities and delivering dependable outcomes for clients — work that lasts well into the future.
Specialised Aggregates has been a trusted supplier of high-quality Australian white rock since 1987. From our Dowes quartzose quarry in Tenterfield, we proudly serve customers across New South Wales and further afield, delivering structural-quality white aggregates for construction and landscaping projects.
The popularity of white quartzose lies in its durability, aesthetic appeal, and versatility, making it a preferred choice for architects and landscapers. Specialised Aggregates’ sustainability procedures and service excellence has established us as a reliable partner, shaping a positive reputation in the quarry sector. We seek opportunities to provide our unique offering of resources from our white rock quarries. Contact us today.
