cases this condition is further exaggerated at the locations
where the handrail posts are imbedded into the concrete
allowing moisture a place to enter the concrete if the posts
are not installed correctly resulting in sections of concrete
falling.
Another common problem is when a unit owner will
cover the balcony with a carpet or some other material
which holds the moisture and does not allow it to drain
from the balcony.
2. Parking garages. The surfaces of the parking garage
exhibit similar problems to the balcony surfaces although
the deterioration can be accelerated by the salts carried
into the garages by the cars in the winter. In many cases
this also leads to problems with the structural concrete
beams and columns as well as steel beams which are
exposed to these conditions. In many cases the expansion
joints which separate sections of the parking garage decks
allow moisture to travel from the top levels to lower levels.
3. Podium decks. In many high rise buildings a podium
deck is installed above parking garages or other parts

of the building. The construction of this podium deck is
typically comprised of a waterproofing membrane directly

drainage plane to allow moisture to be drained and a top
surface that is for public use and may be brick, grass, plant-
