Application Situation
Waterproofing of the Olympic Complex roof.
Application Method
Application was carried out in accordance with Belzona Know-How System Leaflet RPA-1. Firstly the asbestos coating inside the dome was removed. The roof was resurfaced using a cement based screed to provide a good base for the new coating. A fully reinforced Belzona® 3111 system was then applied. 
Belzona Facts
The Application was revisited in 2009. After 6 years in service, there was no deterioration of the roof structure. The coating, although covered in dust following a dust storm, was still in an excellent condition underneath. The coating still provided UV-resistance and was watertight.
