Rock Rolls

Rock rolls are a robust and permanent revetment for use around reservoirs, shorelines, lake edges, streams and river banks. They are cost-effective revetments that are suitable alternatives to rock rip rap and gabions in many scour applications.

When joined together, rock rolls can form a rock roll mattress capable of resisting high velocities and shear stress up to 1200 k/N in high energy river situations. They also accrete silt due to small stone size and can be fully vegetated. This is not possible with rock armour and large rip rap.

Rock rolls provide an instant flexible solution to many scour problems particularly below low water level where pure bioengineering techniques will not function. When used in conjunction with coir rolls, coir pallets or live willow, rock rolls provide a solution which can support healthy invertebrate and even native crayfish populations.
