Certain precautions need to be taken with ballasted rail tracks in order to prevent upward migration of fine particles into the ballast,  diminished bearing capacity of clay soils and creation of voids (gypsum) caused by the dissolution of soils by rainwater. The use of COLETANCHE® NTP4 which is a thick bituminous geomembrane under the ballast is particularly recommended.during  construction and maintenance of rail tracks.
