Abstract
Methods are provided for repairing an existing structure to cover at least a portion of the existing structure with a repair structure. Such methods comprise mounting one or more standoff retainers to the existing structure; coupling one or more standoffs to the standoff retainers such that the standoffs extend away from the existing structure; coupling one or more cladding panels to the standoffs such that the panels are spaced apart from the structure to provide a space therebetween; and introducing a curable material to the space between the panels and the existing structure, the panels acting as at least a portion of a formwork for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the panels. Corresponding apparatus for effecting such methods are also provided.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
