  • Patent number: 11761220
    Abstract: A method covers at least a portion of a surface of an existing structure with a repair structure. The method comprises: providing a standoff, the standoff elongated in a longitudinal direction and operable from an open configuration to a closed configuration; while the standoff is in the open configuration, mounting the standoff to the existing structure, such that the standoff projects outwardly away from the surface of the existing structure; closing the standoff to the closed configuration, the closing of the standoff forming a standoff connector; and coupling a cladding panel to the standoff by engaging the panel with the standoff connector at a location spaced outwardly apart from the surface of the existing structure by a void.

  • Patent number: 9879436
    Abstract: 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.
