Why We Recommend These Products

Rail transport in Australia is a crucial aspect of the transport network. It consists of various track gauges and operates across urban and regional vast areas.

There is an invariable wear and tear performance of the rail infrastructure assets and equipment, which is consolidated by the harsh terrain(s), axle loads, operational specifications and urbanisation requirements or needs.

The installation of the Projex Damtec Sub-Ballast Mat (SBM) improves operational performance and allows reduction of the peak pressure in the ballast, to increase the stability of the track geometry, to effectively reduce the structure-borne sound and static vibrations.
