In November 2016, Wessling Architects completed a multi-phase exterior restoration project for the Healthcare Trust of America at the Wang Theatre on Tremont Street in Boston. The Wang Theatre, constructed in 1925, consists of three coated pre-cast concrete facades on the Tremont Street elevation and two adjacent north and south elevations.
The project began as a City of Boston Ordinance Report survey but upon discovering significant deterioration of the concrete façade, evolved into a full scale exterior façade restoration project. Many of the areas of spalled concrete were in danger of becoming falling hazards to pedestrians below. Therefore, Wessling Architects was tasked with developing a cost efficient long term repair to these areas.
Working in conjunction with the masonry contractor, PJ Spillane Co. Inc., Wessling Architects deemed that repairing the spalled areas with Conproco Mimic, a single component concrete repair mortar, was the most appropriate solution where the was sufficient sound backup masonry. This repair occurred not only applied to the flush portions of the façade, but also at the parapet to recreate the dentil work, cornice band, lion's heads and decorative theatre heads which had deteriorated over time. In cases where the spalling and deterioration was severe and there was no sound backup, Glass-Fiber-Reinforced-Polymer (GFRP) panels were installed. These lightweight, carefully molded panels replicated the original shape of the lion's heads, cornice sections and window spandrels they were to replace. A final finish of Conproco Conpro Lastic, a waterproof elastometric membrane coating, was applied over the entire pre-cast concrete façade to unite the various repair methods and create a uniform aesthetic appearance.
The result of this multi-year restoration effort was a beautifully restored façade that reflects the long history of the Wang Theatre and will continue to invite theatre-goers for many years to come.
