Right on track: heavy-duty grout for iconic bridge rail deck

Client needs + challenges

  • Scheduled supply of large volumes.
  • No delays, fast turnaround, precise delivery.
  • Australian-made products and scalable production.
  • High vibration resistance and strength for rail track pads.
  • UV resistance for exposed track pads.
  • Exceptional service at every step.

Solutions, service + simplicity

We were proud to provide the right solution and support to help our client achieve their objectives – and stay on track – to deliver this complex project.

  • Once the rail height and width were set, formwork was placed around the Delkor Rail Egg Pad (a rail fastener for high vibration and noise attenuation).
  • Megapoxy 206 Ultra was poured into the formwork to lock the rail system onto the concrete rail deck. 206 Ultra is a heavy-duty, flowable, 100% solids epoxy grout – designed specifically for civil engineering and structural applications where strength is imperative.

Standout benefits

  • Supply and service helped keep the project right on schedule.
  • Reduced deck maintenance with more robust and longer-lasting materials.
  • Works estimated to extend the life of the 88-year-old railway corridor by another 120 years.
  • Trains to run more quietly, smoothly and reliably.
