Substructure diagnostic
Our enterprise makes compaction measurements, bearing capacity measurements, stability inspections and prepares expert’s report about these related to construction works and existing earthworks as well. In connection with this activity, it is also possible to make laboratory tests of ballast and to determine soil physical properties.

Besides conventional substructure inspections our company has implemented the utilization of track geometry measurement data in the detection of substructure defects. It is based on the calculation of level moving standard deviation parameter and the analysis of its temporal variation. From its characteristics we can make conclusions about track geometry defects originating from substructural causes.

The level moving standard deviation results of track geometry measurements and the georadar inspections provide a comprehensive view about the substructure condition and assist in planning the location of conventional inspections. / CC BY 3.0
