Rock Rolls provide a permanent, cost-effective alternative to rip-rap & gabions in turbulent and fast flowing applications.
Used around lakes and reservoir edges, shorelines, high-flow riverbanks & streams, rock-rolls provide a flexible solution that gives immediate scour protection, particularly in applications below water.
Rock Rolls can be used on their own to provide erosion protection, but when combined in a bioengineering solution they provide a solid foundation to sit preplanted coir rolls upon, helping to create a fully vegetated revetment, giving long-term erosion control, bank support & habitat creation.
Standard pre-filled sizes 300mmɸ x 2m long, 400mmɸ x 2m long…Greenfix also provide a number of supply options for rock rolls, including un-filled bags & 50m long rolls of netting.
Rock Mattresses provide an instant high performance erosion protection system. Used below water or as a permanent revetment around coastal areas, reservoirs, shorelines, lake edges, streams and river banks. They provide an instant cost-effective revetment that is an alternative to rock rip rap and gabions in high velocity applications. The stone mattress is made up of self-contained chambers, made from 5mm knotless polyethylene netting with a mesh size of 50mm x 50mm. Standard size is 2m x 2m x 0.2m & 3m x 2m x .2m…..Monolithic Rock mattresses can save on rock material, at a lower density than comparable non rip rap non confined revetments.
