BACKGROUND INFORMATION:
This project will provide specialized structural concrete remediation at the Hutchins Street Square Pool (Pool), utilizing pressure epoxy injection to restore the monolithic integrity of the concrete shell and mitigate hydrostatic leakage.
Attached investigations by Siegfried Engineering, Inc. (SEI) and Pacific Coast Leak Detection (PCL), identified active seepage through the deep-end concrete shell. Technical assessments revealed:
* Sub-Structural Fractures: Multiple stress fractures exist within the gunite substrate, likely obscured by the existing fiberglass overlay.
* Permeation Pathways: Hydrostatic pressure is forcing water through compromised pipe penetrations or voids, leading to localized spalling and oxidation of the reinforcing steel (rebar).
* Acoustic Analysis: Hydrophone testing by PCL confirmed that while the structural fractures are significant enough for water migration, they remain subsurface and require targeted injection rather than simple topical sealing.
This project's proposed remediation serves as a medium-term structural solution until a comprehensive remodel and plaster resurfacing project can be phased into the Capital Improvement Plan.
