Damp under vinyl / lino floor in Kitchen

My kitchen is square with one side against the outside wall, 3 walls have all the usual kitchen cabinets and appliances installed leaving a square area in the middle of the floor which is covered in lino up to the edge of the cabinets/appliances.

Underneath the lino dampness forms, but underneath cabinets and appliances around the edge of the room the floor is always dry.

The floor surface is concrete.

I intend to replace the lino with floor tiles.

Have I got a problem or do I need to prepare the floor area before tiling to prevent problems?

Any advice would be a great help, thanks.

i would expect the whole of the floor to be damp.

what's happening is the lino is trapping the damp from evaporating into the air. under the cabinets there must be enough air flow to disguise the damp.

if u are going to use ceramic tiles ie impermeable then ok to go straight down.

if not then would look to put liquid dpm down 1st.
