| Aperio | ||
Aperio has unrivalled railway experience and a team of qualified personnel. The company investigates railway assets including track, earthworks and structures using non destructive methods to provide a representative picture of condition and construction. |
Trackbed surveys measure ballast thickness and map hidden problems ahead of renewals. |
Infrared thermography has been used in tunnels to detect defects such as near surface delamination and has been effective in some cases in detecting blind access shafts. |
A resistivity profile showing a 'lost' structure below the railway. Aperio surveys map unrecorded structures, cavities and ground formations in the railway environment. |
Flexible reporting options for geophysical surveys include linking results to geographical information systems to enable comparison with other rail asset and condition records. This image shows trackbed thickness. |
