TenCate Polyfelt® in Dutch rail renovation

The renovation of a section of railway track near Bodegraven (NL) last October involved the use of TenCate Polyfelt– a geotextile separation material.

ProRail, the rail operators, deployed the largest work train in Europe to carry out this work. The result is a structural, environment-friendly solution.

The work in Bodegraven attracted a great deal of attention: trainspotters and other people who were interested came to take a look at the train.

To reinforce the soil and carry out repairs to this section of the track, ProRail used the largest railway machine in Europe. This track layer is more than 1200 metres long. The train lifts the rails up over a distance of one kilometre and excavates the existing subsoil in three layers, which may be as much as six metres deep. The soil that is removed is immediately cleaned, sieved and – as happened near Bodegraven – placed on top of the TenCate Polyfelt® geotextile, which had already been automatically installed. This separation material received special certification by ProRail for use under the ballast bed.

In the past couple of years more than 500,000 m² of TenCate Polyfelt® and TenCate Polyfelt® Geolon filtration fabric have been installed during similar work.
