The challenge
Years of cement and clinker dust had hardened on the cement mill roofs, adding dead load that led to a partial collapse. Once the dust was removed, most of the roof sheets turned out to be corroded and leaking.
The mills had to be re-roofed, including the collapsed section, while the plant recovered from the incident.
Scope of works
- Rope access roof cleaning from scaffolding towers and lifelines
- Removal of corroded and damaged roof sheets
- Re-cladding of the collapsed section
- Installation of new roof cladding on mills CM1 and CM2
Outcome
Both mills have sound, weather-tight roofs again, without the hidden dead load that caused the collapse. Read the cement mill roof cleaning case study and see the related collapsed structure removal.
