Nanopool protects tunnel with NP® technology

Innovative protective coating demonstrably reduces cleaning costs and increases road safety

Already 17 tunnels in Austria have been protected with the NP® technology.

Since 2007 ASFINAG GmbH has been successfully using NP® liquid glass on tunnel walls to reduce costs.

The comparison between treated and untreated tunnel walls shows that the adhesion of dirt and exhaust gasses is reduced. The cleaning intervals of the tunnels are also minimised from twice annually, to cleaning once only. Cleaning no longer requires chemical cleaners, simply water, and the water pressure can also be reduced from 130 to 30 bar. As a result, the high cost of energy and detergents is reduced greatly.
