Tunnel Coatings

Topcoat commenced work at the Waterview Tunnel in August 2015, and the project was completed in 2017. Click here for more information on the Waterview Connection Project.

The first stage included waterblasting the concrete surface, and application of Sikagard Wallcoat-T Black to a ceiling area of 88,000m². The staged process allowed our night crew to work around the cross passages team.

Topcoat is the NZ licensed applicator for IMC Ceramicoat, and applied the IMC Ceramicoat product in colour Magnolia, to a height of 4m on the tunnel walls and barriers.

This system was also applied in the Johnstone’s Hill Tunnel, Puhoi in 2008, and the Memorial Park Tunnel, Wellington in 2014.

“We were very happy with the work they’d done for us previously, and their pricing was good.

Nothing was a problem for them. Some suppliers will come to you with a list of issues – but Topcoat just gets on with it. They work around any problems, and come up with solutions themselves.

We’ve now got a floor that’s purpose-designed for our industry, and that meets all industry standards.”
