Belzona Facts:

Prior to contacting Belzona, the company had to replace this piece of equipment every 1 or 2 years. An inspection of the Belzona lining 3 ½ years later, in August 2010 showed it was still in place and none of the metal parts were exposed. As a result, the customer asked Belzona for several similar applications.
