Abstract
A retrofit for diverting water leaking into an elevated expansion joint is formed by lowering an applicator that carries an adhesively treated water run-off arrangement into the joint and pressing the arrangement against inside walls of the joint with an expanding bladder under fluid pressure. When the adhesive cures, reducing the pressure collapses the bladder and allows withdrawal of the applicator.
