Moisture pathologies in historic masonry

Moisture in historic structures rarely stems from a single cause. Its behavior depends on thickness, porosity, orientation, salts and thermal cycles.

A serious diagnosis does not begin with the product but with water trajectory. That trajectory determines whether drainage, sealing, material compatibility or detail redesign is needed.

The technical priority is to intervene without betraying the original construction logic. The right solution resolves the conflict while preserving the architectural reading.
