Full rehabilitation of an underground Manhattan parking structure including structural concrete repairs, De Neef PUR crack injection, 458 LF drain installation, and engineered shoring.
United Brothers was engaged as general contractor for the full rehabilitation of an underground parking structure at 370 East 76th Street in Manhattan. This complex structural scope included full-depth concrete patching, De Neef PUR polyurethane crack injection for active water infiltration, and rigid epoxy injection for dormant structural cracks.
The project also included installation of 458 linear feet of 4-inch PVC drain lines integrated with the waterproofing system, and a complex boiler room structural intervention requiring engineered shoring towers and monitored preloading to safely transfer loads during the repair sequence. All work was documented for allowance-based billing and NYC DOB compliance. Project schedule managed through April 2026 completion.
