16.3.5 Moisture detection (3): Decks & balconies
16.3.5.1

General information

Although there are differences in design, materials and construction, decks—plaza
decks, courtyard decks etc—suffer from the same moisture and leaking problems as
low-slope commercial roofs. Improper flashing, inadequately sealed membranes,
and insufficient drainage may lead to substantial damage in the building structures
below.
Balconies, although smaller in size, require the same care in design, choice of mate-
rial, and workmanship as any other building structure. Since balconies are usually
supported on one side only, moisture leading to corrosion of struts and concrete re-
inforcement can cause problems and lead to hazardous situations.
