Repair System Selection:

Although the Navy had considered suspending a heavy fabric from the underside of the thin shell concrete roof in order to protect both personnel and helicopters from falling spalls, it was determined that this was not an optimum solution since it did not prevent additional deterioration of the concrete structure. Also, the cost of this suspended fabric would have been nearly two million dollars, which is about twice the cost of the repair system that the structural engineers recommended to the Navy. The structural engineers recommended to the Navy that the selected repair do the following:

Restore the original structure.

Prevent future deterioration for about twenty-five years.

Limit the expenditure of repair funds.

Accomplish the repair in three months so that the Navy could quickly utilize the hanger bays.

The structural engineers utilizing a repair method that directly attacked the problem of reinforcing steel corrosion and concrete spalling/laminations achieved these objectives. This repair/restoration consisted of the following basic procedures in this sequence:

1.

Removing spalled concrete by hand methods.

2. Applying high strength polymer repair mortar to spalls by hand methods

3.

Applying a penetrating, corrosion inhibiting impregnation to all exposed concrete surfaces.

4.

Applying a protective, anti-carbonation acrylic coating to all exposed concrete surfaces.
