The clean-up operation is under way at the sunken gardens in Douglas.
A large section of wall collapsed, and gardens were submerged in sea water following tidal flooding on Monday.
Douglas Council parks staff have been breaking up the stone by hand, and it will be used to rebuild the wall if possible. The council is awaiting the results of a preliminary survey to see whether the wall can be repaired.
Engineer Ian Clague said: ‘The issue we’ve got is there’s a drop down so we really have to make sure it’s safe enough to stay up in future.’
He said the damage was one of the worst he’d seen during his career.
Meanwhile, head of parks David Hughes said he was praying for rain to wash away the salt from the soil.
He said he would have to wait and see how the flowers fared when they were planted in the spring.
