Floor Detective® Claims and Conditions Guide

Summary

Buckling or upward deformation of resilient plank or rigid core flooring may occur when vapor-impermeable flooring systems are installed over wood substrates located on or adhered to concrete slabs. In these assemblies, wood flooring, plywood panels, or wood-based underlayments are positioned between the finished floor and the concrete. Because wood is a hygroscopic material (a material that absorbs and releases moisture), it expands when moisture content increases. When a vapor-resistant flooring system is installed above the wood layer, the ability of the wood substrate to dry upward may be significantly
