Belzona Facts:

Every few weeks some of these pipes become holed and are traditionally welded. Welding these pipes is typically very difficult and after a very short time the problem reappears at the some point. After the application of the Belzona® solution at 30-40mm along with steel plates the problem stopped. By January 2006 there had been many of these repairs completed and none had become holed again.
