Masonry & Moisture Protection-Restorations

This project for the Church of Our Saviour in New York City was the first phase of our office's Existing Conditions Assessment recommendations. Extensive water erosion was found in the existing limestone cladding which required stone replacements and sculptural rebuilding of the stone architectural detail and bas-relief narratives. After conducting a network of probes, all parapet, gable, and buttress coping stones were also determined to be in need of removal and reinstallation for the application of missing through-wall flashings.

The parish's rectory sits upon the flat roof of the church building, whose setback is an accessible roof terrace. As originally constructed, the tar-pitch roofing was applied under a clay tile in a Portland Cement setting bed. Our office specified and detailed the installation of a cold-applied liquid roofing membrane and a floating paver system.
