About Parking Structures As cities grow in size and population, so does their demand for local parking. High rise parking structures provide safe parking and vehicle protection within inner-cities by making efficient use of vertical space while reducing the horizontal space required of open parking lots. These structures are crucial in providing close-proximity locations for community members to park their vehicles and shield them from the elements. Unfortunately, parking structures are not immune from environmental damage such as water and chloride attack. Therefore, routine maintenance is required in order to protect the structure’s concrete and steel components from failure.
