Fibrwrap Rehabilitation Systems (FRS®) are constantly used because of their technological advantages (under- and near-water applications) on a variety of waterfront structures (piers, wharfs, jetties, etc.). Because of the extremely aggressive environment, these structures are in a condition of constant deterioration, hence they suffer from loss of strength mainly due to corrosion.
The FRS® are developed and installed to these structures in order to provide rehabilitation of corroded sections, extension of service life, seismic repairs, underwater repair of structures, cathodic protection and even enhancement for change of use (e.g. commercial to industrial loads). The FRS® include epoxies developed for partial or underwater curing, pre-fabricated FRP jackets, grouts for the jacketing system and cathodic protection system. The FRS® are designed to regain the capacity of corrosion damaged structures in and around waterways. Also, whether wet lay-up or pre-fabricated, they can be installed on circular, octagonal, rectangular and alternatively-shaped cross sections.
In addition to protecting structural elements and regaining their original strength, the FRS® may also be designed to increase the original capacity for change-of-use retrofit projects.
