Wires for gabions and mattresses may be polyester coated. The wires shall be resistant to chemical attack in the pH range 2 to 9, be resistant to attack by bacteria, and not be attractive to vermin. They shall also be stable over a temperature range of -60℃ to 100℃ and be resistant to degradation by ultraviolet radiation such that strength loss due to 10 years exposure to sunlight shall not exceed 20%.


Gabion mattresses are used for river bank and scour protection

The mesh shall be securely tied to salvage wires to form rectangular panels which shall be securely wired together to form the completed gabion baskets. The ties and connections for each gabion basket shall comprise not less than 8% of its total weight, and the fabrication shall be all to the satisfaction of the Engineer.

Gabions shall be made to the sizes as shown on the drawings. Gabion mattresses shall be made to sizes shown in WAJ Typical details of trenches for sewer pipes and as per MPWH specifications. Each gabion mattress or compartment of a gabion mattress shall be provided with at least 4 cross- connecting wires.

Gabion Mattress is a double twisted hexagonal woven galvanized steel wire mesh compartmented basket with a rectangular mattress shape. The compartment or cells of the mattress are of equal size and dimension and are formed by internal diaphragms being placed within the basket providing even distribution of the stone fill throughout the mattress even after structural movement. Even distribution of the stone fill ensures that the reno mattress maintains intimate contact with the foundation soil.

Gabion Mattresses have been used for channel linings, river training, soil retention, slope stabilization, and other applications successfully throughout the world for over 100 years. Gabion Mattresses offer many advantages over other types of construction materials.

Advantages offered by double twisted mesh gabion mattresses:

are flexibility, durability, strength, permeability, ecology, reliability, longevity, low cost, and an aesthetic appearance.

Flexibility - the most important advantage of using gabion mattresses
Gabion mattress has a flexibility both for the individual unit and the overall gabion structure. The Double Twisted Hexagonal Mesh construction of the units permits it to tolerate differential settlement without failure. This property is especially important when a structure is on unstable soil conditions or in areas where scour from wave action or currents can undermine the toe of the structure and cause structural settlement.

Durability - achieved by high strength material and structural integrity
Material: Gabion Mattresses are built from high strength double twisted hexagonal mesh and connected together to create a monolithic mass structure capable of undergoing structural movement without any loss of structural integrity creating a highly durable structure.

Strength - to withstand forces generated by water and earth masses - Strength value in ASTM A975-97
The strength of gabion mattresses is achieved in several aspects:
breaking strength;
the mesh wire tensile strength;
Pull apart resistance strength of the mesh;
Corrosion resistance of the mesh.

Permeability - Free Draining Structure
The porous structure permits an active air circulation through the wire netting and soil is deposited and plant growth invades the structure, transpiration further assist in removing moisture from the soil being protected.
