Advantages of Gabion Mattress(Gabion Mattresses)
The mattresses possess the strength to withstand forces generated by water and earth masses. The most important and relevant strength characteristics pertaining to gabion mat design standards are the mesh punch strength, the mesh tensile strength, the pull apart resistance strength of the mesh, and the corrosion resistance of the mesh. The strength values of the double twisted mesh are located within the individual product specifications for each product and are represented in ASTM A975-97.
It builts from high strength double twisted hexagonal mesh filled with natural hard durable stone 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.
One of the most important advantage is its flexibility both for the individual unit and the overall. The construction of the units permit 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.
* Low Construction Cost
The installation is very cost effective. The mattress is easy to construct requiring limited equipment, unskilled labor, minimal foundation preparation, no drainage provisions, and low cost stone fill generally provided by a local stone or rock supplier. The structure requires very little if any maintenance and if designed and built properly can be a permanent structure.
Gabion mattresses creates structure that is naturally free draining. Hydrostatic heads do not develop behind gabion and reno mattress structures. Drainage is accomplished by gravity and by evaporation as the porous structure permits an active air circulation through it. Moreover, as soil is deposited and plant growth invades the structure, transpiration further assist in removing moisture from the soil being protected.
