Frequently asked questions
Does the tide affect a basement that is nowhere near the water?
Near the older core it can. A tidal river holds groundwater up along its corridor and that level moves with the tide and the season, so a basement can be damp on a dry week for reasons that have nothing to do with rainfall. Distance from the bank matters less than elevation.
Rain gets in during a storm but not during ordinary rain. Why?
Pressure rather than volume. Coastal storms drive rain nearly horizontally and push it against joints that only ever needed to shed water falling downward. A detail that performs for a year of normal rain can leak in an hour when wind puts the water under pressure.
What should be expected of a period basement here?
That it moves moisture. Stone and lime mortar were built to breathe, and no damp-proof course exists in that construction. The realistic aim is controlling what reaches the outside of the wall and managing humidity in the space, not converting it into a modern barrier.
