Precast concrete provides low on-going costs for maintenance, repair and other needs that add material and labor costs. Generally, precast concrete components, even those exposed to weather, require little maintenance. A regular inspection and routine recaulking of cladding panels every 15 to 20 years is all that may typically be required.
Panels can be washed with strong chemicals and cleaners without losing their color, and UV rays will not cause them to fade, as will happen with paint.
Parking structures, more than any other building type, require routine maintenance. The severity of the wear and exposure demands will depend on the structure’s location, environmental conditions and maintenance schedule. Based on national surveys, precast concrete parking structures provide superior resistance to deterioration. Components produced by PCI-certified plants in particular use durable concrete mixes with specialty curing can be created that cannot be achieved in the field.
In general, there are three types of maintenance: housekeeping, for general upkeep; preventive maintenance, with periodic checkups and cleaning of components; and structural repairs, due to spalling, cracking or other wear issues. All of these are minimized with the use of precast concrete components.
