The erosion of Permanent Way sub-grades can result in the loss of rail track alignment, leading to costly maintenance and complications caused by the temporary track closures. The traditional solution has been to use a sub-ballast and/or a graded-sand layer to prevent the upward movement of fine sub-grade particles. Geotextiles has been adopted to maintain separation between the adjacent sand/ballast layers to prevent sub-grade erosion. We at Viridi Contracts offer high quality Railway Track Bed Geotextiles with end-to-end railway track erosion consultancy.

The rapid passage of trains applies dynamic loads to the soil resulting in very intense compression and decompression cycles. The foundation, being thus subjected to fatigue stresses, can undergo fracturing up to the point of collapse. Under these conditions, both very thick layers of aggregate, and frequent and expensive maintenance are required. Railway Track Bed Geotextiles laid on the base of the railway ballast, constrains the aggregate by laterally confining it, and creating the necessary tensile forces. The aggregate’s thickness may therefore be reduced to give cost savings.

Thermally bonded geotextile suitable for good granular sub-grade soil
Manufactured from high tenacity UV stabilised virgin polyolefin fibres to provide long term durability in all soil types
Excellent uniformity with high permeability and low pore size for soil filtration
