Retaining Wall
Noise Barrier Systems
Permacrib Environmental Noise Barrier Systems are constructed of timber components to form a series of parallel silos. The silos, (centre of the wall) are infilled with a suitable material. Infill may consist of crushed rock, river gravel or unprocessed pitgravels.
Several wall designs are available including vertical walls which use internal posts.
Post specifications are matched against wind and seismic loads. Concrete, steel, timber or other posts of suitable strength and design life may be used.Permacrib systems can be constructed to any length and will adapt to terrain contours with ease.
