Damp Proofing

Small damp patch on concrete kitchen floor

I have a small damp patch on a concrete kitchen floor (Victorian terrace) where it was filled in following the removal of a chimney breast. The new kitchen units are now in and the damp came through later so I suspect there was no damp-proof membrane in that one patch. Taking the whole floor up is not an option. Would a liquid damp proof membrane painted over the main part of the kitchen floor but around the cabinet legs be sufficient to then lay flooring over this? If not, what options are there for flooring without removing the new kitchen. Update in answer: hard to know if it was always damp because we laid floor, had a water softener leak and then the floor bubbled. Thought it was due to the leak (which has been mended) but after drying out the rest of the floor is ok but this separate patch remains. This all happened over about a year, the patch is now surface dry but remains damp when tested with a meter.
