Although concrete is a relatively durable construction material, preventive maintenance and necessary corrective actions are required to extend the useful life of parking structures. Parking facilities experience harsh exposure conditions which can contribute to accelerated concrete deterioration and adversely affect the life expectancy of the structure. Quite often, owners and operators have to repair deteriorated structures with only 15-20 years of service (Figure 15–1). It is not uncommon for repair costs to exceed $10.00 per square foot. In addition, the repairs disrupt the facility’s operations and cause inconveniences for users, which result in a loss of revenue.
