Removal and replacement of a failing waterproofing system in place on an upper level patio (over occupied space) at the Providence Portland Medical Centers’ Child Center. The patio is frequently accessed by staff and patients and therefore required a waterproofing system design to withstand rigorous foot traffic and the placement of patio furniture and healing aids.
- Removal and replacement of the existing concrete roof pavers, waterproofing membrane, and sheet metal flashings. Several rows of brick masonry units were removed to allow for proper installation of copper flashings following the installation of the waterproofing system.
- Modified bitumen cold-process adhered waterproofing membrane with granule surfaced base flashings.
- Fabrication and installation of 20 oz. copper counter-flashings within the brick masonry wall and completed with the reinstallation of brick masonry.
- Fabrication and installation 20 oz. copper coping and skirt flashings along the exterior parapet wall with stainless steel support flashings.
- Installation of 24” x 24” concrete deck pavers and supports for maximum protection of the new waterproofing system; pavers designed and installed in a custom checkered pattern for improved appearance.
PRC documented the construction process with Quality Assurance inspections and Field Reports issued to the Tam. The project was closed out as specified, with all warranties issued for the installed systems.
