Rock Mattresses are a “thin” gabion and traditionally has been used in applications such as creek and channel linings where long term scour is an issue. The confinement of appropriately sized stone within a mesh effectively increases the resistance of such rock to scour for a given flow condition. Rock Mattress product is typically supplied in plan area of 6m x 2m with varying thickness products ranging between 0.17m to 0.3m.
One of the most important advantages of double twisted mesh gabions & Rock mattresses is their flexibility both for the individual unit and the overall gabion or rock mattress 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.
Gabions & Rock Mattresses built 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.
Strength
Double Twisted Hexagonal Mesh Gabions & Rock Mattresses possess the strength and flexibility to withstand forces generated by water and earth masses. The most important and relevant strength characteristics pertaining to gabion and rock mattress 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.
Gabions & Rock Mattresses create structures that are naturally free draining. Hydrostatic heads do not develop behind gabion and rock 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.
Gabions & Rock Mattresses offer an environmentally sensitive solution to soil retention slope stabilization. Gabions and Rock mattress structures utilize natural stone for their stability and strength. Constructed of natural stone fill the gabions are naturally porous allowing interaction between the land and the water table. Soil will generally be deposited in the small voids of the stone fill material during drainage and draw down and will promote vegetated growth inundating the structure. Over time in some applications the structure can become so inundated with vegetation as to no longer be visible. Vegetation, plant and tree growth can be implemented at the time of construction utilizing several methods to ensure vegetation occurs immediately.
The overall strength characteristics offered by the double twisted hexagonal mesh gabions and rock mattress listed above and the long successful history of the material usage world wide ensures that the double twisted mesh gabions and reno mattresses will perform as designed.
Gabions & Rock Mattress installations are very cost effective. Gabions & Rock Mattresses are 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. Gabions & Rock Mattress structures require very little if any maintenance and if designed and built properly can be a permanent structure.
Gabions & Rock Mattresses constructed with care can create visually pleasing structures. Unlike other types of materials such a modular block walls the gabion stones do not discolor due to drainage. In fact the longer a gabion or rock mattress structure is in place and becomes inundated with vegetation the more aesthetic it becomes.
