Tip 1 if a concrete floor is damp all over it is hard to isolate the moisture source.
Damp proof course below floor level.
The outside ground level should be at least 150mm below the damp proof course and ideally avoid hard surfaces next to the stone as water will splashback in heavy rain causing damage to the stone.
As it dries out the damp retreats slowly back to the points of ingress so if you are not able to see any isolated damp areas either ventilate and heat or shut all the doors and windows and use a dehumidifier.
When constructing an extension or a new build home it is important that damp proofing measures are taken during the initial construction phase itself.

This may be unavoidable in tenements built tight to the pavement.
The selection of materials for the damp proof course and its various methods of applications in buildings is discussed.
Generally damp proofing keeps moisture out of a building where vapor barriers keep interior moisture from getting into walls.
Depending on the extent of the rising damp this can be a more costly and extensive job to repair.
These days damp proof membranes are required in the construction of all new buildings to prevent rising damp.
As it dries out the damp retreats slowly back to the points of ingress so if you are not able to see any isolated damp areas either ventilate and heat or shut all the doors and.
