Rock Rolls offer flexibility and the fact they arrive on site pre-filled with stone greatly reduces installation time and therefore cost, compared to in-situ filled gabions. Rock rolls and mattresses can also be installed during live flow situations, which is not possible with standard gabions.
The £21.7 million flood defence scheme involved works on 16 individual reaches of the river and it reduced the risk of tidal flooding to 488 homes and 94 commercial properties in Sandwich. Client – Jackson Civil Engineering working on behalf of the Environment Agency.

The Environment Agency are responsible for the river bank stability at Railway Lane, Lewes and recognising the integrity of the existing blockwork facing was deteriorating began to look into solutions to this challenge.
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.

Salix were awarded a design and build contract to prevent further erosion of a section of the riverbank and reinstate a scour hole threatening a high pressure gas pipeline on the River Tywi.
The integrity of the existing blockwork facing was deteriorating as a result of the tidal inundation and draw-down cycles together with areas of groundwater seepages emanating from the slope profile.
