Tensar geogrids stabilize the ballast and sub-ballast trackbed structure and work to distribute the imposed loads more efficiently over the underlying area. This leads to a reduction in the required layer thickness while still meeting the required factor of safety. The geogrid also limits lateral spread and thereby minimizes track settlement.
