Customer Location: Concrete products manufacturer, Bedfordshire, UK
Application Date: August 2017

Products:
Belzona 1111 (Supermetal)

Belzona 5811 (Immersion Grade)

Application Situation

The customer manufactures concrete beams, blocks and other structures at their large site in Bedfordshire. The cement silo is a vital part of their plant

Application Method

Application was carried out in accordance with Belzona System Leaflets TCC-1 and TCC-5. Steel plates were bonded to the lid using B1111 where required to repair the holed areas before applying two coats of Belzona 5811 to provide overall corrosion protection.

Belzona Facts

Having the silo lid refurbished rather than replaced saved the company in excess of £21000 for a new lid and the contractor fees. In addition, the Belzona solution allowed them to carry on production as the silo could still be used safely whilst work was being carried out saving a huge amount of money in lost time and revenue.
