This project is a good example of how cathodic protection can prolong the service life of a structure and /or reduce its overall construction cost.

Conventionally, a sacrificial thickness is allowed in the design of steel H-piles to cater for corrosion loss in time, leading to the use of much larger piles and hence substantial cost increase. In this project, an impressed current cathodic protection system (ICCP) was designed and installed to protect 242 pieces of underground steel H-piles with a design life of 100 years. The average length of the piles is about 45m and the section is 305mmx305mmx223kg/m. With this method, the size of the steel H-piles are reduced with substantial savings in material and construction costs.

The scope of works included the following: Detailed design and preparation of workshop drawings for the ICCP system
Supply and installation of ICCP system, including anodes, reference electrodes, cables, junction boxes and transformer rectifiers
Testing and commissioning of cathodic protection system

A newly-completed luxury residential apartment in the heart of Jakarta was having an urgent requirement to strengthen the reinforced concrete beams and slabs at the mezzanine due to a sudden change in the function at this floor level. As the residential development was gearing up towards full completion and residents taking over their units, the requirement for the strengthening will need to be completed within a very short period of time.

The engineering team of PT. Fyfe Fibrwrap Indonesia was contacted by the project consultant and contractor to submit the strengthening proposal based on their requirement for strengthening of the beams. The project was duly confirmed upon approval of the strengthening proposal and the installation team was mobilised to complete the work. The Tyfo® Fibrwrap® System was successfully installed to the affected beams within the project time-frame as set forth by the contractor.
