Latest MCI® Applications
National Bank, Vati Building
Case History #132

The Vati Building was suffering from corroded rebar which was causing the concrete to expand and deteriorate.

Before applying any of the MCI® products the spalled concrete was removed. Then the cavity was sprayed with MCI®-2020 corrosion inhibitor liquid and the bonding agent, MCI®-2023, was applied. Next, MCI®-2038 repair mortar was used to fill the area. After that had set, a finishing spray of MCI®-2020 covered the repaired section and the surrounding area.

The Vati Building was now repaired and protected against corrosion with the effective, long-lasting Cortec® MCI® products.


Plankenton Street Parking Ramp
Case History #121

The City of Milwaukee, Wisconson-Plankenton Street Parking Ramp was deteriorating from deicing salt being carried on automobiles and the steel rebars were corroding. The ramp is located in the heart of downtown Milwaukee and is a valuable source of revenue. The city wanted a fast and economical way to renovate and protect the parking ramp with the least amount of down time. The Specifying Engineer and the City wanted to renovate the structure with the best products and procedures. MCI®-2020 was an important part of the renovation system.

MCI®-2020 was applied to the concrete decks by the renovation contractor at the rate of 150 square feet per gallon (4m2/liter).

The MCI migrated through the concrete to form a protective, corrosion-inhibiting barrier on the structural steel. MCI®-2020 was chosen as part of the system because its corrosion inhibiting properties will extend the life of the structure and reduce maintenance.


Black Sea, Russia
Case History #119

The city needed to protect an eroding concrete bridge foundation. The unusually adverse weather conditions threatened the integrity of this 35-year-old structure. They wanted an immediate repair solution. Even more importantly, they wanted to protect the structure from further deterioration. Otherwise, they faced the even greater expense of replacement.

MCI®-2020 was applied onto the prepared concrete surface in order to provide protection of the rebar after the repair work was finished. Next, the prepared surface was coated with the primer that included Z-40 and fibers. The thickness of the applied primer is 3-4 mm. Then a water-resistant layer was applied. This was a poly-cement that included fibers, migrating corrosion inhibitor MCI®-2000 and a Xypex concentrate. This served as the base for the hydro-insulation layer. Next the hydro-insulation layer was applied. This was a poly-cement material with the addition of Z-40. The ratio of cement to sand was 1:1.5. The thickness of the layer was 5 mm. There were at least two layers applied. Lastly, a final clear coat sealer was applied, which worked as a water and salt repellant.

The repair procedure, along with the Cortec leading technology products, provides a high quality, long-term repair, as well as a visually attractive service site.

The following suggestions were made for future applications:

• Use more Migrating Corrosion Inhibitors in order to prevent
corrosion on the exposed rebar.

• During surface preparation, use Cortec rust remover, which
would allow faster and better preparation.

• Detail the concrete joints with additional protective layers.
