Major repairs on parking garages cause several issues for property managers. Disrupting tenants, unexpected costs, and safety concerns are just some of the challenges to deal with. So, how do we avoid these unwanted headaches? Below are five key indicators that your garage could use preventative maintenance, so you can avoid major repairs.
Signs of Water Leakage
Leaking water is a clear sign that your parking garage is in need of a tune-up. The longer it is left unattended, the more expensive the consequences become. Two indicators that water leakage is occurring are: exposed metals rusting and rust stains along the walls.
Water and parking garages just do not mix well, so sitting water is obviously not something you want present in your garage. A simple drain installation or surface overlay will prevent future, larger problems.
Failed expansion joints provide another avenue for water to penetrate and reach the reinforcing steel and “T” to “T” connector plates. Repairing expansion joints is much simpler than resolving issues created by corroded reinforcing steel and connector plates. Detecting expansion joint problems and reacting quickly will be very beneficial in the long run.
Delaminated, Spalled, Horizontally Cracked, and Vertically Cracked Concrete
Concrete is bound to crack at some point. Delaminated or spalled concrete is when a piece of concrete detaches from the structure. Along with delaminating and spalling, vertical and horizontal cracks in the concrete also represent threatening areas of weakness. These issues are problematic as they can lead to structural damage because they allow water to reach the garage's reinforcing steel.
Exposed Rebar (Reinforcing Steel)
If you can see rebar, you have a problem that deserves swift attention. When rebar is introduced to water, it corrodes and expands up to eight times its original size. This undesirable introduction usually is the result of a crack in the concrete that allows water to travel through and reach the rebar. The force of the expanding rebar causes more damage to the concrete around, which creates greater access for water and more corrosion. It is imperative to stop this compounding cycle as soon as possible.
Essentially, the goal is to keep water away from the parking garage's reinforcing steel. The damaging and compounding cycle never gets better on its own, and the longer these warning signs are ignored, the more serious and costly the repairs become.
