Cement Plant Mills CM1 CM2 Cladding Replacement

Roof cleaning and replacement of corroded, leaking roof sheets on cement mills CM1 and CM2, including the section that had collapsed.

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.
