Belzona® Repair To Concrete Stock Chest



Pulp & Paper (PLPR)



Tanks and Chemical Containment Areas (TCC)


Customer Location:

Containerboard Paper Mill, North Alabama, U.S.A.


Application Date:

February 2007


Application Situation:

Concrete block tank holding stock being fed to the #1 Paper Machine. It has a pressure release valve to allow blow-by in case of emergencies and it failed. The pressure grew to the point that the solid, reinforced concrete lid lifted and stock blew out the sides.



The top not only lifted, it blew chunks out of the sides all the way around. Job was to fill in the the voids created by the stock and to seal the edges against further leaking.
