TRACKSIDE
Track renewals site investigation
For track renewals SI our services include:
- Drainage – assist in characterising existing drainage including visual catch-pit inspection, mapping location, investigating condition
- Ballast – using GPR and targeted sampling during various stages in the life of a trackbed. Stages include targeting renewals, designing trackbed, quality control following renewals and interim assessment of ballast condition.
- Formation – non-invasive geophysical techniques and minimally invasive cone penetration testing methods combined with conventional intrusive SI methods such as trial pits and cable percussive boreholes.
- Subsidence – former mineworkings and infilled sinkholes can represent a significant risk to the safety of a railway. A range of geophysical methods suited for use in the trackside environment are offered that can help identify the location, depth and size of structures.
