• Clean and dry the basin areas for repair in an environmentally friendly manner • Remove and dispose of all existing basin joint membrane material(s) • Prepare joints for replacement - Mechanically clean all seams and adjacent surfaces to remove dirt, debris, old sealant, loose concrete, and biological growth. Pressure wash the seams and cracks with a minimum of 3,500 PSI. Allow to dry thoroughly before recaulking. • Replace all joints - Install appropriate closed-cell backer rod where required. Apply specified joint sealant to all seams in accordance with the manufacturer’s installation guidelines. Tool and finish joints for proper adhesion and appearance. • Repair all cracks in basin floor - Inspect and map all visible cracks in the basin structure. For minor surface cracks (<1/16”), apply penetrating crack sealer. For structural or active cracks: Chase cracks to appropriate width and depth (1/4” x 1/4” minimum). Clean and prep the area. Fill with epoxy or polyurethane crack injection material or patching mortar as per severity and location. • Conduct quality assurance (QA) with the FMPA Project & Plant Manager by means of standing water in the basin for signs of air bubbling, level drop, sweating/seepage, etc., with adequate time to address any quality issues within the allotted outage availability window
