Industry:

Power (POWR)

 
 

Application:

Tanks and Chemical Containment Areas (TCC)

 
 

Customer Location:

Power Station, Queensland, Australia

 
 

Application Date:

June 2008

 
 

Application Situation:

Damaged Sulphuric acid bund at power station

 
 

Problem:

Spills of sulphuric acid over many years had significantly damaged the containment capabilities of the bund leaving it questionable about whether it could contain a major spill.

 
 

Products:

Belzona 4111 (Magma Quartz)

Belzona 4311 (Magma CR1)

 

Substrate:

Concrete

 
 

Application Method:

Application was carried out in accordance with Belzona System Leaflets TCC-9 and TCC-15. After removing damaged sections of old coating, the underlying concrete was neutralised using HP water and bicarbonate of soda. After drying damaged areas of concrete were rebuilt with belzona 4111 before coating overall with Belzona 4311 system.

 
 

Belzona Facts:

Being a Power Station that operates 24/7, there is limited time to carry out any significant repairs. The Belzona materials were chosen for their high performance and fast curing properties that kept downtime to a minimum whilst ensuring that the bund would remain effective for many years to come.
