Belzona Facts:

The cost of replacing the runner would have been $19,500. No other type of repair was considered viable. The total cost of the repair utilising Belzona® was $600. There are many such units in the area and several of them have been treated in the same manner. The output of the repaired unit is greater than when the equipment was new.
