Project Highlights
- Revolutionary solution for long-term concrete repairs
- Included substantial concrete repairs and reinforcement
- Specialized protective coating system selected based on chemical exposure and vehicle access
Project:
The chemical building at a large Nuclear Power Plant stored both hazardous and general chemicals required for operation and maintenance of the power plant. Three of the storage rooms were equipped with adjacent outside drainage basins that would contain spills. Also, the loading/unloading and building access areas on each end of the building functioned as secondary containments for spills.
The protective coating for these containments had deteriorated, and the concrete slabs and substrates had cracked over the years. Thus, the containment structures required rehabilitation and protective coating replacements to restore the integrity of the system.
Solution:
After an initial review with the owner, it was determined that a repair could be completed using a combination of advanced materials including high strength polymer grouts/concrete, carbon fiber strengthening systems and a fiberglass reinforced chemically resistant protective coating.
Results:
The facility life has been extended significantly with the completion of the rehabilitation work. The work was completed without interruption of normal plant operations.
