Reno mattresses are structures made of hexagonal woven wire Mesh Type 60, commonly referred to as double twist wire mesh as per SANS 1580:2005. Reno mattresses are filled with rock at the project site to form flexible, permeable, monolithic structures for river bank and scour protection, channel linings for erosion control and underwater pipeline protection. The steel wire used in the manufacture of the gabion is heavily zinc coated. When required, a 0,5 mm nominal thick PVC coating is then extruded over the galvanised wire to provide enhanced protection for use in aggressive environments such as in salt water, in water carrying a high abrasive sediment load or wherever the risk of corrosion is present. In order to reinforce the structure, all mesh panel edges are selvedged with a wire having a greater diameter than the mesh wire. The Reno mattress is partitioned into cells by means of diaphragms positioned at approximately 1m centres.

 The advantages of Reno mattresses(Terra mesh):

Permeability of the front face, guaranteeing drainage of the backfill

Flexibility, enabling the structure to tolerate differential ground settlement without compromising structural integrity

Ease of construction

Significant soundproofing characteristics (18-28 decibel)

Structural safety in case of fire near the front face

The versatility of gabions, which allows the formation of a structure with vertical, battered or stepped front face as required and minimization of environmental impact.
