Whatever the size or scope, we have high-quality construction aggregates for every conceivable project.

With over 60 quarrying operations across the country, backed by a nationwide transportation network, we are a major supplier of fine and coarse aggregates to the UK construction industry.

It includes readily-available products for all types of construction projects, including drainage solutions, rail ballast and sea defences.

We have a wide range pf products including granite, grit stone, basalt, limestone and ironstone. These typically are crushed graded into Type 1, Type 2, 600 series materials, bulk fill material, pipe beddings, gabion stone & track ballast. We also provide sand products to 6mm/10mm/14mm/20mm grading, 20mm ballast, washed concrete sand, building sand and fill sand and gravel products to 20mm/ 40mm grading.

With an aim to become the UK’s leading supplier of sustainable construction materials, we provide a number of recycled and secondary construction aggregates. These include Aggneo, a natural secondary aggregate with the same quality and performance as newly-quarried construction aggregate.

We’re constantly striving for innovation and greener solutions, and by reprocessing and reclaiming aggregate which would otherwise become waste material, we are driving a circular economy in infrastructure, industry and the building sector.
