Washer beneath in concrete, lifted up (9)
I believe the answer is:
launderer
'washer' is the definition.
(I've seen this before)
'beneath in concrete lifted up' is the wordplay.
'beneath' becomes 'under' (under means beneath or underneath).
'in' is an insertion indicator.
'concrete' becomes 'real' (similar in meaning).
'lifted up' says the letters should be written in reverse (in a down clue, letters go up).
'real' reversed gives 'laer'.
'under' inserted inside 'laer' is 'LAUNDERER'.
(Other definitions for launderer that I've seen before include "Washer" , "Money dealer" , "Cleaner (of clothes, linen)" .)
