Abstract:
Concrete parking decks are subject to several unique problems which can initiate or aggravate deterioration. These include negative-moment cracking, cold joint cracking, cracking due to embedded conduit runs, and other water related damage. This paper will deal with these problems encountered during the rehabilitation of the parking decks in a 3-story, 28-year-old garage. This structure was not maintained for its entire life, except for the installation of a waterproofing membrane on the top deck about 8 years ago. The topics covered are: 1) inspection and testing what to look for and specific test procedures; 2) causes and recommendations for the repair of some of the problems encountered.
