Abstract

See full text

An existing concrete structure is repaired by covering at least a portion of the existing structure with a repair structure. Standoff retainers (each comprising an elongated member, fastener-receiving features and standoff-engaging curves) are mounted to the existing structure. Fasteners extend through the one or more fastener-receiving features and into the existing structure. Standoffs are coupled to the standoff retainers and extend away from the existing structure by extending the elongated members through apertures in the standoffs and locating each of the standoffs at a location of one of the standoff-engaging curves. Panels are coupled to the standoffs at locations spaced apart from the existing structure. Curable material is introduced to the space between the panels and the existing structure. The panels act as a formwork for containing the curable material until the curable material cures to provide a repair structure cladded by the panels.
