The Belzona System allowed for the repair to be carried out during the plant shutdown, saving time and money while undergoing maintenance. These pipes transport 1,400 tons of ore each day. To date, the pipe is perfectly adhered to the concrete. Belzona 1812 needs to be applied only to the bottom part of the pipe, since this is a sacrificial product.
