Reno Mattress (DP-GBRM)

Reno Mattresses are thin flexible cages (less than 500mm thick), made of hexagonal double twisted woven wire mesh. The Mattress is divided into cells by internal diaphragms/partitions positioned at 1 m centres to limit rock fill movement during high flow conditions.
Reno Mattress:
Material of Reno Mattresses:
1. Galvanized wire
2. PVC coated wire
3. Galfa wire.
Use of Reno Mattresses:
Reno mattresses are used for river bank and scour protection, channel linings for erosion control, and embankment stability. Reno mattress are filled with rock at the project site to form flexible, permeable, monolithic structures to promote rapid growth of natural vegetation. The base section of the Reno mattress is divided into compartments and filled with stones at the project site. With lids secured, Reno mattresses form flexible, permeable, monolithic structures.
Advantages of Reno mattresses:
1) Flexibility The woven mesh system has the capability of withstanding unexpected and/or localized stresses due to ground settlements and scour by deflection while maintaining its structural integrity.
2) Permeability The stone fill allows the water to seep through the structure while retaining the soil, therefore no additional drainage is required to relieve the hydrostatic pressures.
3) Cost Effective, Easy to Build Reno mattress construction does not require skilled labor because they are very easy to build. Standard construction equipment can be used. Structures can be built in stages, if necessary, and baskets can be prefilled and launched to enable the installation under water. Site assistance is available from any Maccaferri area office.
