Written by  Oct 31, 2017

The road owner seek solutions that can give a light and maintenance-friendly tunnel, that also feel safe for the motorists. White coating can contribute to make the tunnel lighter. The right amount of tunnel lighting can also be used, often in a combination with lining and coating. 

CemPro Whitecoat is a white-colored and water-repellent mortar developed in consultation with road authorities for spraying primarily on tunnel walls, but can also be used on other surfaces. When used in tunnels, the tunnel will become significantly lighter and therefore it may have a traffic safety effect.

This Whitecoat is a white through-colored and drop repellent, but at the same time diffusion open mortar. This effectively prevents the penetration of dust, oil, salt and other substances into the surface. In order to get it clean, high pressure can therefore be used according to standards without adding soap or chemicals. The whitecoat last long and keep the color well, and is used where there is a need for a strong and washable surface. The product can withstand frost and also inhibit carbonization.

By spraying the walls at a height of 3.0 - 3.5 meter, provides a surface that helps the tunnel to be perceived as safe. This type of measure can also give a good optical effect.
