How are damaged canal locks restored?

How are damaged canal locks repaired and returned to service?

The affected section is isolated and drained, then engineers stabilize and repair the lock before refilling and reopening it.

Alex Clarke's sister, a civil engineer, describes isolating and draining a lock so repair crews can reach the damaged structure. Stabilization and reconstruction use methods related to coastal works and flood defence. Specialist river and coastal engineering teams can perform the work even when another organization owns the canal. She recalls a river-construction project for flood defence during her time at Capita Symonds, although she cannot remember its location.
