Sea and river defences
Materials from our quarries are used for vital river and sea defence work. We supply rock armour stone that complies to CIRIA specifications, together with rip-rap, gabions and walling stone.
Our 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.
Rock armour is also used to protect the UK’s shorelines as it is extremely durable. With a range of sizes available to meet specific requirements, we are a major supplier to sea defence projects.
All of our Garside Sands range of natural silica sands contain a high silica content - typically above 90% - and a sub'angular grain shape. Our specialist silica sands are quarried at two locations within the UK: Leighton Buzzard and Levenseat, located in Scotland.
