Project Overview

Recipient: The Basilica Landmark

Thirty monitors were installed to measure moisture readings in the upper reaches of the Basilica of St. Mary. Restoration projects had been put on hold due to previous water infiltration and the damage that was caused by saturation of masonry walls and ceiling plaster. Such infiltration takes a long time to dry. There were concerns that plaster was continuing to absorb moisture from the attic insulation or the masonry walls.

A lift was used to visually inspect and manually "sound" ceiling plaster on three representative arches where they meet the exterior wall. The monitoring sensors were then installed on the ceiling and in the attic. The results from the first readings confirm that the masonry walls are drying out. Restoration projects can resume.
