Safety and Environmental Protection Measures:
A tarp system was used to collect paint chips - to avoid contamination of the
roof gravel.
Unusual Job conditions:
Due to the height of the building, it was not feasible to use sandblasting or to economically remove all existing paint on the crane system. By using water
and a specialized tarp system the roof gravel was not contaminated.
Evidence of good performance:
No rusting or deterioration of coating system after one winter and semi-frequent use of the crane.
Why Termarust was used:
Termarust and the contractor provided a 5-year warranty on leakage from pack rusted joints and connections and a minimum 25-year coating system service life.
