Carnsew Quarry is the largest inland quarry in Cornwall, located toward the centre of the developing area lying between Redruth, Falmouth and Truro. The quarry is sited within the Carnmenellis Granite Intrusion producing high quality coarse-grained silver-grey granite, in a full range of products to meet demand in all sectors of the construction industry. Our Ammann asphalt plant produces a range of asphalt products and has the ability to incorporate recycled material, such as RAP (recycled asphalt planings) into base and binder mixes. The quarry has been granted planning for extraction until 2095.
The on-site technical department provides laboratory, design and testing services enabling it to respond to customer’s specific requirements and ensure material quality is actively managed and conforms to relevant standards and specifications.
Our recent £1.5m investment in a mobile crushing plant at the quarry extends it's capability giving us greater flexibility in production and the ability to meet future market needs rapidly.
