Railway Track Ballast Support

A highly cost effective solution for the reinforcement of ballast over a soft subgrade are Tensar biaxial geogrids, which bring significant benefits to railway engineers. Tensar biaxial geogrids can be applied to two major areas - beneath and within the railway track ballast:

• Direct ballast reinforcement reduces the rate of track settlement and reduces maintenance cycles.

• Reinforcement of a granular sub-base layer beneath the railway ballast to increase the bearing capacity of the track foundation.

• An alternative to increasing the depth of ballast, or adopting chemical stabilisation.
• Improved rail ballast performance allows consistent high speeds to be achieved.
• Reduction of the rate of permanent settlement.
• Avoids the need for excavation of soft soil and replacement with thick layers of imported fill.
• Reduced maintenance due to a proven increase in the intervals between maintenance interventions.
