Reno Mattress also known as rock mattresses, are thin, flexible rectangular mesh cages made from double twisted woven wire mesh. The cages are divided into cells and filled with rock to limit movement during high-flow conditions. Because of their flexibility, Reno Mattresses are used mainly for hydraulic applications such as weirs, and for scour protection along riverbanks and embankment stability in channel linings. Mattresses can handle water velocities in excess of 6m/sec for long durations. FUNCTION Reno Mattresses are manufactured from double twist hexagonal wire mesh with new polymer coating, and are supplied 6m x 2m dimensions with a thickness less than 500mm. Reno Mattresses are filled with stones on site to create a flexible, permeable and monolithic structure for use in river and canal bank protection works as well as erosion control and scour protection of slopes. Hydraulic testing of Reno Mattresses has shown that by containing rock within the cells of the mattresses the resistance to rock movement under high flows is dramatically reduced resulting in the use of smaller and less rock for channel lining works. Reno Mattresses are highly permeable making them well suited for promoting the regeneration of plants along water course and in environmentally sensitive sites.
