It was intended to have a solution that would recover the original capacity of the structural resistance, lasting and easy to apply. Given the location of the structure, it was also important to avoid stopping of structural service during the maintenance work.
As a solution to that, the DYNAMIS consultants recommended as a solution the application of the FX-70® system, applied since the 70's by our company, with excellent results
The FX-70® System consists of applying to each column to repair a fiberglass jacket, lost formwork, integrant part of the column structure protection system , protecting the concrete from any aggression of the marine environment.
Prior to the application of the FX-70® Jackets, it is necessary to carry out a cleaning of the support by removing all the concrete spalling parts and passivating the reinforcements with the S & P TECNOPROT-EPOX epoxy base product.
All Fiberglass Jackets are tested by the American ASTM standard and are custom made to suit project requirements. In this case, translucent circular Jackets with a diameter of 42 cm by 3 mm thickness were applied to the original rectangular columns .
Since the average height of the pillars exceeds 5 meters in height, for easier application, the protection system was applied in two sections.
