Limestone isn't all that different from poured concrete- when you insulate it the temperature drops, and the moisture migration slows. When you also factor in the vapor retardency of the it changes the direction of the major flow from inward (toward the basement) to upward, drying toward the above-grade exterior.

Systematic in situ measurement of moisture distribution on the facades of limestone rock-hewn heritage. A linear regression equation between limestone's electrical resistance-based moisture content (ω c) and the gravimetric moisture content (ω o) was obtained.. The surface of the limestone statues contains more moisture signalling a …

The findings reveal that the statues' moisture content is higher than the background wall between the statues, signalling a greater potential for deterioration on the surface of the limestone statue. The primary source of moisture appears to be gaseous water in the atmosphere, which accumulates in the micropores through capillary condensation.

Investigation of elastic weakening in limestone and sandstone samples from moisture adsorption Abstract: Elastic and mechanical weakening from water saturation are widely known to occur in sedimentary rocks, and particularly in carbonate rocks. To improve our understanding of the physics underlying this phenomenon, ultrasonic (f ∼ 0.5 MHz ...
