Laminate planks lock to each other and float
Laminate is a photographic layer under a hard transparent wear surface, bonded to a high-density fibreboard core with a milled locking profile on every edge. Nothing fastens it to the building. The planks lock to each other and the whole floor rides free on top of the substrate, which is why a laminate install is fast and why it can be lifted later without damaging what is underneath. Floating construction is also where the two failure modes come from. A floor that cannot slide, because a plank is pinched under a door casing or run tight to a wall, buckles when it expands. A floor over a substrate with a hollow in it flexes at the joint until the lock wears loose and the seam opens. Both are prevented at the preparation stage and neither can be fixed afterwards without pulling the floor back up.
