Crystal House Façade and Balcony Repairs

Cyrstal House is a 12-story apartment building consisting of two cast-in-place concrete structures constructed between 1962 and 1965. Severe spalling and delamination of the balcony top surfaces and soffits, deteriorated mortar joints, cracked and spalled bricks as well as systemic water infiltration into the building were some of the problems that affected the integrity of the structure and quality of life. A comprehensive condition assessment was provided for the Crystal House apartment building along with repair recommendations for the preventive maintenance of the balcony and exterior enclosure.

The project included various brick masonry flashing repairs above leaking windows, the removal of spalled and delaminated concrete slab and nosing, and the cleaning of reinforcing bars and placement of the corrosion inhibitor induced concrete. The damaged balcony rails were removed and replaced with new rails to meet current building codes, an acrylic coating was applied to the balcony top surfaces, soffits, and nosings along with the replacement of deteriorated mortar joints and damaged bricks and glazed CMU blocks on the façade. Additionally, the damaged concrete windowsills were removed and replaced, and sealant was re-sealed on the vertical joints between the masonry bricks and the glazed CMU blocks.
