PROBLEM

Water was leaking from an above ground parking lot into sub-level garages through cracks and faulty joints in the concrete.

APPLICATION

1. The entire surface was pressure washed at 150 bar.

2. MCI®-2023 passivating grout was applied as a primer to joints and corners of the parking lot, followed by a top coating of MCI®-2038 finish repair mortar.

3. MCI®-2020, a water based, topically applied, migrating corrosion inhibitor, was sprayed over the entire surface and allowed to penetrate for three days.

4. After the three day waiting period, the entire surface was again pressure washed at 150 bar.

5. MCI®-2022, a silane/siloxane based sealer containing migrating corrosion inhibitors was sprayed over the entire surface.

CONCLUSION

All leakage stopped immediately after the repairs were made. There is still no leakage 14 years after the application.
