Vertical Instability
Vertical instability is rocking floor panels which do not rest securely on the pedestal head or grid system. Panels move up and down when weight is applied.
- Missing gaskets
- Missing stringers
- Missing pedestal pads
- Dirt/Debris on pedestal/grid caused by lateral instability
- Subfloor dirt/particulates forced on grid by air conditioning
- Removing stringers, not replacing properly
- Removing panels, not replacing properly
- Swollen woodcore panels
- Warped panels
- Moving equipment on floor too soon after installation
- Tipped pedestal
Causes:
- Reduction in plenum pressure from air conditioning
- Tripping hazard for personnel
- Edge trim is exposed, subject to breaking (If edge trim is broken, laminate surface is exposed to chipping)
- Dirt/Debris drops into subfloor
- Subfloor dirt/particulates forced on grid by air conditioning
- Permanent panel damage
