Bubbling or Swelled Edges
Swelling or Bubbling (Laminate)
Floor Detective® Claims and Conditions Guide
Summary
Swelling or bubbling in laminate flooring is a moisture-driven condition that occurs when liquid water or prolonged moisture exposure enters plank joints and is absorbed into the fiberboard core. Laminate cores are hygroscopic by design and will respond dimensionally to liquid exposure. Moisture entering seams is absorbed by the core, leading to expansion and visible joint distortion such as edge lift, peaking, or crowning. Expansion at joints can disrupt mechanical engagement within the floating system. Liquid intrusion at seams differs from normal vapor equilibrium exposure, which does not typically create the same magnitude of thickness swell. The presence of swelling does not independently establish manufacturing defect; origin determination requires correlation
