PROBLEM

The electric transmission support poles are made of precast concrete. Years of exposure to chloride and carbonation attack caused concrete spalls and cracks on many of the poles. The spalling cracks compromised the ability of the poles to structurally support their loads. To compound the problem, the rural local of the poles made access difficult.

APPLICATION

The loose, damaged sections of concrete were removed. VpCI®-386 was applied to the rebar with a brush. MCI®-2000 was added to the repair mortar to repair the area. A cementitious coating of MCI®-2020 and a cement wash were brush applied as a finish coat, giving additional protection and an esthetically pleasing appearance.

CONCLUSION

To replace a power pole in the field would have cost $900. By using Cortec’s MCI®-2000, MCI®-2020 and VpCI®-386, the poles were brought back to almost new condition at a cost of $250 – a savings of $650 per pole.
