Bardon Aggregates can provide a range of materials for sea and river defence works from various sources on a national basis. Rock armour stone which complies with CIRIA specifications is available from stock, together with rip-rap, gabions and walling stone. These are produced from strategic units throughout the UK and Norway, all controlled directly by Bardon Aggregates. Road, rail and sea transport can be co-ordinated to service the exact requirements of specific contracts as appropriate. Extensive and flexible loading facilities are available ensuring continuity of supply can be maintained. In the North West Bardon Aggregates has an alliance with Railtrack / Nuttalls as preferred supplier.

River Defence Bardon Aggregates rock armour has been widely specified by the Environment Agency and consulting engineers for river revetment and diversion contracts. In such situations, natural rock is more harmonious with the environment than steel piling and longer lasting than timber. An effective interlock between blocks can be achieved on either a coursed or random joint pattern.

Sea Defence Extremely durable to the harshest wave power, and used in major sea defence projects throughout the UK, Rock Armour from Bardon Aggregates is widely specified by leading consultants and is the UK's principal supplier of armour stone for sea defence projects. A range of sizes is available from stock, held at strategic locations throughout the UK and Norway. These materials can be supplied to meet with specific customer and site requirements.
