Reduce Differential Settlement & Maintenance in High Impact Zones

Areas subjected to heavy stresses at bridge approaches, diamonds, turn-outs and crossings create the highest maintenance liabilities for operations.  The GEOWEB 3D soil confinement system is effective in reducing maintenance in these high impact areas.  By stiffening the ballast layer, movement and deflection is limited and maintenance in these critical transition zones is significantly reduced.

“The area with the GEOWEB system has been subjected to 25 MGT this year with no deflection. The other end of the bridge without the GEOWEB system has settled over 2 inches and has been resurfaced twice”. Chief Design & Construction, FEC Railway Bridge Approach project.

GEOWEB Benefits for Track Ballast Reinforcement

Railway engineers worldwide have relied on the GEOWEB technology to create high-stiffness roadbed foundations under track, and at bridge approaches, diamonds and turn-outs. The GEOWEB system is extremely effective in stabilizing track subgrades, and has even more beneficial value in soft soil areas.

  • Reduces Rock Size and Cross-Section Thickness: Rock confined in the 3D GEOWEB structure replaces expensive larger stone, reducing aggregate size by up to 10X. The aggregate thickness & cross-section can be reduced by up to 50%.
  • Less Down-Time: The GEOWEB material can be quickly installed to make any necessary repairs and minimize costly track disruptions.
  • Installation Benefits: Due to the ease of installation, the GEOWEB material can be installed by the railroad’s on-site crews.

GEOWEB 3D Benefits Compared to 2D Geogrids

GEOWEB 3D Benefits:

  • Reduces ballast depth 2-3 times.
  • One-step direct deployment over soft soils.
  • Limits differential and long-term settlement through hoop strength and active/passive resistance.
  • Ideal for difficult or limited access.
  • Fast deployment = limited down-time.
