What is TrackTex
TrackTex is a multilayer geocomposite which provides an effective alternative to sand blankets and filter geotextiles to control subgrade pumping under ballast. It is the result of more than a decade of research by railroad engineers and materials scientists.


TrackTex is a multilayer composite with a unique microporous filter media protected by specially engineered protective nonwoven geotextiles. The filter is an orientated microporous polymeric film with a series of microcells and interconnecting pores, characterised by its relative strength and ability to transmit vapour.

The geocomposite can effectively facilitate the passage of liquid under pressure, but the pores are such that the passages of clay fines is prohibited. Without pressure, water cannot pass through the filter, therefore any underlying clay formation will, over time dry out and have an improved modulus. TrackTex therefore improves track quality.

This unique, patented system has been shown to extend maintenance intervals where mud-pumping has caused trackbed failure by more than 25 times, meaning significant savings over any available alternative.
