Avoid Costly Repairs by Maintaining Your Parking Structure

Indications You Need Parking Structure Restoration


  • Water leakage: Water and parking structures don’t mix! Leaking water is a clear sign that your structure needs repairs. The longer leaks are left unattended, the more expensive the consequences can become.
  • Ponding: Standing water is a huge issue in parking structures that can cause a tremendous amount of damage over time if not addressed early. Drain installation can prevent future, larger problems.
  • Expansion joint failure: Detecting expansion joint problems and reacting quickly to make repairs is very beneficial in the long run. Failed joints provide another avenue for water to reach the reinforcing steel and connector plates.
  • Horizontally or vertically cracked concrete: Concrete that has spalled or is cracking represents areas of potential structural damage that needs to be addressed. Cracks let water reach the structure’s reinforcing steel causing it to erode.
  • Exposed rebar: If you can see rebar, it deserves immediate attention. Introduced to water, rebar corrodes and expands up to eight times its original size. This is due to water penetration into the concrete.

Water is the number 1 cause of parking structure deterioration. Water-saturated concrete can freeze, expand, and spall. Combined with oxygen, water can also cause corrosion of the concrete reinforcing. Exposure to deicing salts accelerates this process. As reinforcing steel expands as it rusts, this process also leads to concrete spalling. Spalled concrete provides less cover or protection of the reinforcing which leads to further (and accelerated) deterioration if not repaired in a timely manner.
