High ground levels can make a damp problem look like “rising damp” — when the real issue is moisture bridging into the wall from outside.
At this property, the external level was too high against the masonry, allowing moisture to bypass the intended damp protection and keep the wall wet at low level.
The first step is proper diagnosis: check external levels, drainage, bridging and defects before reaching for chemical damp proofing.
