Problem:
-Corrosion Control Australia was approached by the Project Manager for a large fertilizer aeration shed and asked to inspect and advise on some of the issues they were having at their facility.
-They were having serious structural issues in one section of the roof due to advanced corrosion that had affected roof purlins and roof sheeting.
-They asked us to design and implement an emergency repair plan for the corroded purlins and roof sheeting, including treatment of the advanced corrosion inside the aeration shed.
-Some images of the condition of the facility before treatment are below;
Challenges Faced:
-The working environment in the aeration shed was one of the most extreme we have come across in terms of its corrosiveness and danger to human health.
-We had to employ all our years of experience working in extreme environments to come up with a solution to address roof corrosion, install new purlins, all the while keeping our crew safe and working to a tight schedule.
-We were also very limited with our time frame to get access to the work area and were dealing with extreme heat, humidity, toxic vapours and compromised roof structure that was sagging dramatically.
-While working in the aeration shed, all operators had to have respirators and gas meters to measure gas vapours at all times.
