What was involved
- Surface preparation back to sound concrete, with the deck profiled for adhesion.
- Detailing at the ballast retention edges, where water would otherwise track down the structure.
- Continuous spray-applied membrane across the deck — no laps, no seams.
- Work sequenced around rail traffic, with the deck returned to service the same shift.
