Competitor Failure Brings Belzona® Back



Power (POWR)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

Power Plant, Birmingham, Alabama U.S.A.


Application Date:



Application Situation:

Sulfuric acid containment area. Failed coating allowed chemical leakage into the environment.



Competitor coating failed within two years. Belzona was asked to coat the concrete since Belzona® 4311 had been on the sulfuric acid tank itself for almost 12 years.



Belzona® 4311 (Magma CR-1)

Belzona® 4111 (Magma Quartz)

Belzona® 5811 (Immersion Grade)





Application Method:

Application was carried out in accordance with Belzona Know-How System Leaflets TCC-9 and TCC-15. Damaged concrete was repaired with Belzona® 4111. Coated the acid side of the containment area with Belzona® 4311 and the caustic side with Belzona® 5811.


Belzona Facts:

Belzona® 4311 was applied to the acid tank in 1988 and 12 years later was still perfect other than a little staining. The client had used a cheap coating in containment area first and after it failed decided to spend a little more money to make it last a long time. 8 years later and minor repairs are all that are needed on the Belzona.
