Belzona Facts:

The worn concrete in this public building had become a health and safety hazard. Damaged areas were rebuilt with Belzona® 4111 & 4141. The underside of the stairwells was coated with Belzona 3111 to prevent moisture from entering the concrete. Belzona® 5811 was used to protect the stairs and balconies, and a non-slip system was created by incorporation of aggregates mixed into the Belzona® 5811. Three years later, this application was still in great condition with only a few areas needing to be touched up.
