Gabion Mesh Mattresses

Gabion mattresses are used for river bank and scour protection

The mesh shall be securely tied to salvage rectangular panels which shall be securely 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 abion Mattress is a double twisted hexagonal woven galvanized steel artmented basket with a rectangular mattress shape. The compartment or of the mattress are of equal size and dimension and are formed by internal diaagms 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 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 mattressesGabion 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 integrityMaterial: 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 A975-97The strength of gabion mattresses is achieved in several aspects:breaking strength;the mesh trength;Pull apart resistance strength of the mesh;Corrosion resistance of the mesh.

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

Mattress geometry and material properties

Galvanised and PVC coated Gabion Mattress

The gabion mattress manufacturer must be ISO 9001 certified and the published technical data and values must be verified by Third Party Quality Assurance according to DIN 18200.

Gabion Mattress 375mm thick for sloper scour protection including filter fabric or concrete slope protection inclusive of necessary design where directed by Engineer.

Gabion Mattresses for Flood Protection Embankment

Triple Twisted Hexagonal Mesh Gabion Mattresses are mostly used in projects of Flood Embankment and intake works. Gabions types are boxes and mattresses. Aerct supplies quality gabions system for flood protection, with detailed requirements for the gabion ric, filter fabric, stones and construction of gabions work as following.
