PROBLEM

The cooling towers of this processing facility had severe concrete deterioration, spalling, and corrosion damage. The question was if the structural integrity of the towers could be saved at a substantial cost savings over replacement cost.

APPLICATION

The spalling, cracked, and loose concrete was removed by jet blasting. VpCI®-423 was used to remove heavy corrosion from the rebar. MCI®-2023 was used to immediately protect exposed and cleaned rebar from corrosion. MCI®-2038 and MCI®-2039 were used in combination to repair concrete, protect structural steel from corrosion, and restore structual integrity. To protect areas that were structurally sound, and did not require repair, a topical application of MCI®-2020 was spray applied to the concrete surface. MCI®-2020 will migrate through the concrete and provide protection to the structural steel.

CONCLUSION

The contractor was able to restore and renovate the cooling towers, bringing back both structural integrity and aesthetics. This was done at a substantial savings to the owners over replacement.
