A system and method for repairing and reinforcing a pipeline includes a pair of opposing composite wrap bands that are located on the external surface of the pipeline and positioned a predetermined horizontal distance from a jointed section of the pipeline. A composite wrap is then applied over the bands to create a bridge that spans the bands and forms a cavity above the jointed section. A second pair of bands located on the external surface of the bridge provides structural support. An actuator within the bridge monitors the pressure within the cavity and activates upon the presence of internal pressure, indicating that a gasket failure has occurred. A fitting may also be inserted into the bridge in order to pressurize the cavity and test the repair.
