Belzona Facts:

The conventional repair by welding was done previously without success. The welds cracked soon due to the induced stresses and brittle condition of the engine casing. All conventional repair companies refused any repair. After application and test runnings of the engine the customer was fully satisfied with the results. Belzona solution was time and cost effective and saved the customer replacement costs.
