Belzona® Restores Acid Flow By Refurbishing Concrete Channel

 
 

Industry:

Power (POWR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Coal-fired power station - Scotland

 
 

Application Date:

May 2001

 
 

Application Situation:

A channel used to contain and transport sulfuric acid.

 
 

Problem:

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

 
 

Products:

Belzona® 4181

 

Substrate:

Concrete

 
 

Application Method:

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

 
 

Belzona Facts:

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.
