Doming (Resilient Plank)

Floor Detective® Claims and Conditions Guide

Summary

Doming in resilient plank flooring is a condition in which the center portion of a plank becomes elevated relative to its edges, producing a convex surface profile across the plank body. The condition reflects internal dimensional stress and curvature behavior occurring within the plank structure itself rather than upward movement of the entire flooring system. Because resilient planks are multi-layer composite constructions, differences in dimensional response between layers may create internal stress that causes the plank center to rise while the edges remain lower or maintain contact with the substrate. Doming may affect isolated planks, repeating groups of planks, or larger installation areas depending on the contributing mechanism. Visibility commonly increases under directional or reflective lighting, especially when light travels across the centerline of affected planks. Proper evaluation requires differentiation from curling, edge lift, buckling, peaked joints, or telegraphing. The timing of visible appearance alone does not independently establish causation. See also Curling, Cupping, or Edge Lifting, Peaked End Joints, and LVT and SPC Floor Problems for broader context.
