A nozzle utilized to grout or fill cold joints and cracks formed in or occuring at structural corners. The nozzle includes a tip which is defined by converging planar surfaces about an axial opening. The nozzle tip defining surfaces include a relatively large area which is separated from the nozzle axial opening for wall contact to permit the nozzle to be secured by an adhesive or bonding agent to the corner walls before injection of the grouting material or sealant.
