100 Year-Old Copper Plant Reinforcement

The constant exposure to vibrations, moisture and chemicals in this copper facility caused significant degradation over a century of operation. The client was faced with a $26 Million price tag to tear down and replace the structure, not to mention millions in lost production. For roughly $10 Million, HJ3 and its installation partners, leveraged the benefits of CarbonSeal to revitalize the entire facility over a 5-year period, with little to no interuptions to plant operations.
