Abstract:

The authors have investigated and repaired a number of premature inservice failures of masonry paving systems in recent years. These systems have become common, built over underground structures, frequently garages. Usually a waterproofing membrane is employed between the paving system and the structure. These pavements can be high maintenance paving systems, probably in any climate, but in many instances service life is drastically reduced. The failure of these systems has resulted in substantial costs for repair, reconstruction and liability coverage. This paper explores the nature of the failures on several recent investigative projects and the causes of the failures, and presents the authors' recommendations for improving the design and construction techniques in order to provide a longer service life.
