Profile: Zetica Ltd. specializes in 3D mapping and site investigation services. Our trackside provides a holistic, fit-for-purpose approach to investigating the rail environment. Its services range from high speed GPR for ballast condition assessment to total route evaluation. Ballast condition survey provides objective information on track ballast condition that helps to cut the costs of maintenance and renewals. It scans track ballast condition at high speed using train-mounted multichannel GPR equipment linked to positioning systems and integrated with the results of track geometry surveys. The stability of the survey platform and repeatability of the data facilitates automatic processing and integration with track geometry data to forecast ballast renewal, formation renewal and track maintenance. Landsweep™ is used to locate underground storage tanks, locate buried pits & foundations, locate buried utilities, detect buried hazards on brownfield sites, map groundwater surface & flow paths and map depths to clay aquitard.
