Meaning and Definition
A phenomenon where ground moisture travels upwards through porous building materials (like brick, stone, or plaster) by capillary action, often causing damage to walls and floors.
Used more broadly to describe any insidious, creeping problem that starts from a low or foundational level and gradually causes widespread damage or decay, often hidden until significant harm is done.
Dialectal Variation
British vs American Usage
Differences
The term is far more common in British English due to the prevalence of older buildings with solid walls and lacking damp-proof courses. In American English, the specific technical term is less frequently used in everyday conversation, though understood in construction/real estate.
Connotations
In the UK, it strongly connotes a serious, costly property defect. In the US, it may sound more like a technical description without the same immediate cultural recognition of severity.
Frequency
High frequency in UK property surveys, DIY, and renovation discourse. Low-medium frequency in US equivalent contexts.
