About This Project

Battery Parking Garage, was the first garage built by a public agency and finished in 1950.  It was subsequently expanded in 1968 to it's current capacity.  Located at the southern tip of Manhattan, the facade is subjected to severe weather and deterioration from salts and pollution.  The aged concrete surface was seriously degraded with extensive corrosion of exposed steel structural rebar. The MTA needed a cost-effective and long-term solution that would provide a weather and water repellent finish, while helping to mask the unsightly cracking and help minimize the appearance of extensive patching and beautify the exterior facade.  
Challenges Aged concrete was seriously degraded and required extensive restoration.  Intensive water penetration and spalling conditions had caused steel structural rebar to corrode and become exposed to the elements.  The entire concrete surface had extensive hairline cracking which was further allowing water to penetrate adding to the accelerated corrosion of steel structure and the concrete itself.  
Solutions A mineral finish was chosen, and applied in combination with a silane water repellent to provide the concrete structure with long-term protection from water penetration and weathering.  Further, various grades of mineral textures were used to fill-in cracks further helping weatherproof the aged concrete.  The texture also provided the final project a uniform appearance, masking the patched areas and surface cracks.  Penetration of the sol-silicate finish also helped consolidate and strengthen the aged concrete surface.
