NEW YORK, NEW YORK

Project History
Constructed in 1987, the twin twenty-story buildings marked
the beginning of Harlem’s urban renewal. The two concrete
buildings showed varying stages of spalled concrete,
corroded reinforcing steel, and diagonal cracking. A majority
of these problems were caused by a lack of sufficient
concrete coverage for the rebar. WASA selected ECB,
Conpro Set, Forment, and M3P Stain as a complete repair
and protection system. This combination was the most cost-
effective way to blend repairs and prevent water intrusion.
Corroded rebar was cleaned and treated with ECB, an anti-
corrosion coating and bonding primer. Forment, a form-and-
pour repair mortar, was used to build out the window heads
and sills. Conpro Set was trowel applied wherever formed
repairs were not practical. M3P Stain, a semi-transparent
mineral silicate stain (which will not peel, blister, or flake),
was custom color matched to the original substrate to
provide uniform color as well as long-term protection
from carbonation, chloride intrusion, and water entry.
