Masonry consultant Richard Irons points to gaps in the masonry needing repair at the Kennebec Arsenal on Arsenal Street in Augusta on Wednesday. Irons explains that the masonry breaks down over time due to weather, and without repair, water and moisture seep into the building. A team of masons from the Maine School of Masonry is making repairs to buildings built between 1828 and 1838.
