    Causes:
  • Lateral instability
  • Air forcing dirt and debris on grid system
  • Unsealed cutouts
  • Missing edge trim
  • Improper maintenance of subfloor
  • Flooding of floor surface causes build-up of residual water and chemicals on stingers and pedestals

 

    Consequences:
  • Vertical instability
  • Structural damage to other components
