Terramesh, although an old invention, are quite popular today.
Terramesh a wirework container filled with rock, broken concrete, or other material, used in the construction of dams, retaining walls, etc. Nomally there are two kind Terramesh baskets: Hexagonal wire mesh made flexed Terramesh basket and Welded wire mesh made Terramesh basket.
The Advantage of Terramesh:
1 Easily installed and long life
The Terramesh barrier is made from Class A Galvanised mesh, or together with a PVC coating making it very weather and corrosive resistant. Installation is achieved using local unskilled labor, and no plant is necessary.
The installation of a gabion clad or freestanding Terramesh wall using the right rock type can be very visually appealing to the observer.
The Terramesh barrier can be used as a solid barrier structure alongside roads to protect from vehicle crash damage, can also be used as a cladding to an existing brick building to achieve a much higher level of sound dampening.
4 Enhanced noise blocking and absorption
The Terramesh because of its rough nature and bulk volume easily archive the purpose of blocking and absorbing loud noise. For example a truck has a noise level of about 80 db, the one meter thick bulk gabion can reduce noise by 60 db as shown in the diagram below.
5 Density of Terramesh
The infill of the barrier wall being very dense and heavy in nature will allow for enhanced sound absorption. Most of the sound with a one metre wall will be reduced.
