Damp rising through concrete floor

[whitehart]

hi all, i have a timber built ground floor with i believe concrete oversight below the void, damp is coming up through this, is there anything i can apply to this to stop it coming through??

thanks in advance.

make sure its well ventilated and all the airbricks are clear,and the concrete is free from debris,The damp will dissapear if this is done,Its not unusual for damp or water to appear from time to time.Especially in wet weather
