Concrete Cast-in-place Conventionally Reinforced Parking Garage
Durability of Parking Garage Structures Note 1 March 1994
The purpose of this best practice series on the Design, Construction, Maintenance and Repair of Parking Garages is to inform Property Managers, Project Managers and Project Leaders on the essential requirements in obtaining a durable parking garage structure. The objective of this note is to summarize the main points which relate to Concrete Cast-in-place conventionally reinforced parking structures which are the most common structural system.
General
Premature deterioration of parking structures became apparent
in the mid 1970's. The main cause of this deterioration is the
increased use of chloride based de-icing chemicals used to melt
snow and ice on our roadways. The salts carried into garages on
cars migrates through pores and cracks in the concrete resulting
in the corrosion of reinforcing steel.
Durable parking structures can be built provided proper planning
and attention to design details, quality controlled construction
and a comprehensive maintenance program is followed.
