I went to inspect the garage this evening just before I go and order the timber tomorrow morning and found something quite concerning - quite a fair amount of water/moist in the rear corner of the garage. I can't see where it's coming from and given the amount present (see attachments), I'm not sure it can be explained by water ingress, surely?
Can anyone suggest where this may have come from and whether this is a typical appearance of water coming from something external?
