Geosynthetics are finding a broad range of uses in Railways. Well thought out concepts and designs provide permanent answers to technically demanding construction problems. High-tensile geogrids and wovens reinforce unstable ground, and as no expensive soil replacement is necessary, they also reduce construction costs. The easy handling characteristics of geosynthetics speed up progress on site. Geosynthetics are used as a separation layer to prevent the structural layers from mixing with the underlying ground - as can be seen in the animation.

Main applications in Railways:

foundations of earthworks on soils with low-bearing capacity

reinforcement of embankments over pile caps, vibro-stone columns, etc.

reinforcement of retaining walls and extra-steep earthwork slopes

separation of original ground and load-carrying layers

safety of railway infrastructure in areas prone to subsidence

access roads and transport routes

subgrade dewatering
