Thanks for the reply the back wall looks wet up to about 50cm right across but there is no grey salts...but the back of the house gets no sun so that might have something to do with it I guess. The front of the house is fine it seems to just be bad where the water sit. The soil is thick clay as well so I guess it won't drain easily. I'm gonna try and put some drainage in this summer. Have you any suggestions on how to remove the salts? Thanks

Which would cause foundation movement

are you suggesting a wet slab is impossible?

A wet slab is not impossible, its just that it would be obviously wet as the DPM would contain dampness within the slab so as to have soaking wet internal floors and the associated issues to other parts of the structure

The pattern of dampness and being on the external wall only, with no other issues, would not suggest a mains water leak

What ground slab would that be?

A concrete slab is above the DPM
