Belzona Restores Acid Flow By Refurbishing Concrete Channel



Power (POWR)


Áreas Know-How:

Tanks and Chemical Containment Areas (TCC)


Cliente / ubicación:

Coal-fired power station - Scotland


Fecha de aplicación:

May 2001


Situación de aplicación:

A channel used to contain and transport sulfuric acid.



The concrete channel was deteriorated from the acid. A previously applied bituminous screed was failing which caused peaks and troughs in the channel.



Belzona® 4181





Método de aplicación:

The application was carried out in accordance with Belzona Know-How System Leaflet TCC-15.


Hechos Belzona:

The Belzona® 4181 leveled out all the peaks and troughs and it offers excellent impact resistance should any of the steel channel plates be dislocated and dropped during maintenance. Belzona® 4181 was the best solution because the channel is frequently exposed to sulfuric acid above ambient temperatures.
