Tensar Geogrid SSLA30

Tensar SSLA30 geogrid is a large aperture biaxial geogrid specified by Network Rail under PADS number 57/200822

The benefits

Reducing the rate of ballast deformation has several long-term benefits:

• Maintain track geometry: by restricting the movement of the ballast particles, the horizontal and vertical alignment of the rails is maintained for longer
• research has shown that the maintenance cycle can be extended by a factor of around three
• reducing the frequency of maintenance also reduces the rate of ballast degradation caused by the tamping tines and so extends ballast life- a virtuous circle.
• Transition zones: smoothing the track profile at the interface between rigid and low stiffness formations. e.g. At approach embankments to underbridges
