Rock Rolls are an excellent option for providing erosion control protection to resolving problems where pure bioengineering techniques will not function.
Rock Rolls are a cost-effective alternative to rock rip-rap and steel gabions & mattresses. When used below the low water level they provide a solid but flexible foundation on top of which our pre-planted coir rolls can be installed. Rock Rolls can form part of a bioengineering solution when used in conjunction with coir rolls, coir pallets and wooden revetments. The roots of the aquatic plants will quickly grow and establish into the voids of the Rock Rolls giving long-term erosion control, bank support and habitat enhancement.
In the right application Rock Rolls can be used to very good effect on their own. Pre-planted Rock Rolls can be supplied to site specific requirements. Please ask for details.
