Architect Harry Weese constructed the Northwestern Mutual low-rise building at 611 E. Wisconsin Ave. In 1964. The rebar and concrete construction that presented Weese with so many possibilities as an architect faced challenges in the midwestern climate. Moisture had corroded the rebar, and this expansive deterioration had pushed out the concrete, creating even more opportunity for future moisture damage. Masonry Restoration, Inc. Was tasked with cleaning the entire facade, Complete Sealant Remediation and repairing over 1800 holes in the concrete structure.
Two crews worked 20 hours daily to minimize the potential impact on Northwestern Mutual’s office. Special care was taken to match the aggregate concrete as closely as possible.
The restoration reinforced compromised facade components, reduced vulnerability to moisture intrusion, and improved the performance of the surrounding materials. Together, these outcomes strengthen the building’s exterior systems and extend service life.
