The client spent around €10,000 for the application. Compared to the €50,000 that a new auger screw would have cost. This was a considerable saving – even more so considering that the client would normally have had to buy a new auger screw every year, which they avoided thanks to the Belzona repair. As a result so far the client has been able to save around €300,000 over the last 6 years.
