Belzona® 5831 (ST Barrier)

Belzona® 9211 (SuperGrip Aggregate)

Problem: Roof of chemical tank was suffering severe corrosion but due to the highly explosive nature of the tanks contents, no hot works or mechanical tools could be used. The customer wanted an anti corrosion system that would bond with minimal preparation and be flexible enough to move with the tank. As the whole roof is subject to regular inspections, they also wanted a system that could offer good traction under foot on this domed surface.
