Belzona Facts:

First mill done in 1997 checked in 1999 and no change in clearances measured. Welding and machining considered but production losses would have been too great. Belzona application completed in 33-hour shut down with no production losses. Equipment and peripherals more realiable leading to increased quality and production.
