Use & Purposes
Rock Mattresses are a “thin” gabion and traditionally have been used in applications such as creek and channel linings where long term scour is an issue. The confinement of appropriately sized stone within a mesh effectively increases the resistance of such rock to scour for a given flow condition. Rock Mattress products are typically supplied in plan area of 6m x 2m with varying thickness products ranging between 0.17m to 0.3m.
Rock mattresses be supplied as either a heavily zinc coated, Galfan® unit or may be supplied with an additional layer of plastic coating over the zinc coated, Galfan® wire to afford additional protection in locations where corrosion is likely to be a problem.
Link Mattresses provide a highly versatile solution of earth retention and erosion protection for designers and contractors in a wide variety of applications. Link Mattresses are used in a wide of hydraulic structures. Link Mattresses are low profile and constructed of double twisted hexagonal woven galvanized steel wire with internal diaphragms that create compartments or cells. The compartment or cells are of equal dimensions and spacing to provide even distribution of the stone fill throughout the mattress even after structural movement. Even distribution of the stone fill ensures that the Link Mattress maintains intimate contact with the foundation soil.
