Application Method:

The application was carried out in accordance with Belzona Know-How system leaflets TCC-9 and TCC-15.

 
 

Belzona Facts:

The customer was impressed that this permanent repair was completed in five days. The first application was recently inspected after eight months because of an acid spillage during maintenance and the Belzona was still as good as the day it was first applied. Belzona® 4311 was chosen because the bund is frequently exposed to spillage and has proven to withstand the chemicals. Belzona® 4181 allowed rebuilding and protection of the channels whilst providing erosion resistance to the flow of acid.
