Terra System, company for track construction and stabilization – that has an exclusive cooperation with Gremmler Bauchemie GmbH, uses since 2012 only GREBOPOX® for ballast bonding. Its splendid characteristics and the fact of doing no harm to the environment have been confi rmed repeatedly by comprehensive tests conducted by neutral authorities. Our resin GREBOPOX® is certifi ed from the German EBA-Institute (Eisenbahnbundesamt) for the use on the tracks of the deutsche Bahn. Since nearly 20 years, our ballast bonding resin, labeled fi rst as KRYORIT®, than AgriTec® and now GREBOPOX® has been used successfully for national- and international track construction.
Favourable processing characteristics
In contrast to ballast bonding systems based on 2 component polyurethan resin, our GREBOPOX® ballast bonding material is especially developed for outside jobsides.That means, GREBOPOX® is low sensitive to humidity and can be used as well on wet ballast surface as during slight raining (drizzel). Warmed up it can be processed starting at an air temperature of 2°C. Because of its warm temperature our ballast bonding systems applied on ballast surfaces spreads equally, thus bonding even down to a depth of 30 cm (depending on the size of the ballast) is possible. Another advantage are the pot life of 20-30 minutes and the extended hardening time of 3-6 hours (ground temperature approx. 20°C-10°C.
