Terratex® 4050 is a needle punched, non-woven, staple fibre geotextile manufactured from virgin polypropylene fibres to give outstanding puncture, abrasion and permeability properties.
Terratex® 4050 is a separator and filtration geotextile for use between the track ballast and a sand layer or granular sub grade. Extensive and continual testing and development of the product has demonstrated its class leading mechanical strength and hydraulic properties, coupled with its proven long service life under dynamic loading conditions.
A filter/ separator placed between the subgrade and ballast has to overcome a number of obstacles to remain efficient.
This can include the possibility that sharp ballast could tear the geotextile and/ or the geotextile might also become highly tensioned under the load of the ballast above.
