Tunnel Coatings

Waterview Tunnel Project

Work commenced at the Waterview Tunnel in August 2015. The first stage includes water blasting the concrete surface, and application of Sika Wallguard T- Black.

The staged process allows our night crew to work around the cross passages team. This project will continue well into 2016, with 20% of the required 88000m2 of ceiling completed.

IMC Ceramicoat Magnolia will be applied to 4m on the tunnel walls and barriers.This project is due for completion in 2017. Click here for more information on the Waterview Connection Project.
