Belzona Facts:

The customer had previously tried to weld a steel patch on to the end covers but it had failed. There were no new end covers in the warehouse and to order some would have meant 3-4 weeks of down time, thus the customer was delighted when Belzona solved the problem within two days, saving time and money.
