GEOfabrics Limited has specifically developed GHP3RT to serve the demanding requirements of the rail industry. It has a full Railtrack approval certificate for use as track ballast separator and drainage wrap.
GHP3RT is distributed on behalf of GEOfabrics to the UK rail industry as Terratex geotextile by Aqua Geocomposites Ltd. About 100 km of track was renewed using Terratex beneath the track ballast.
