A95 Spey Bridge: preserving a heritage structure

The ‘New’ Spey Bridge

This is the New Spey Bridge. It was the second-largest concrete arch span in the UK at time of construction.

Well, it was new in 1931.

Now? Not so much. In fact, it now carries a level 7 Historic Significance Rating.

As part of the ongoing maintenance cycle for this ageing structure, AQURON 7000 spray-applied hydrogel treatment was chosen as an alternative to cathodic protection and to prevent further degradation.

The treatment provided protection of the steel reinforcing, but also the concrete itself to provide durable, corrosion-resistant concrete for the overall structure. The structure is waterproofed, and protected from reactive contaminants.

AQURON 7000 can play a key role in the CIVIL-TECT^® protection system for existing concrete infrastructure.
