Abstract
Explains the phenomenon of osmosis in resin flooring systems, focusing on how moisture movement within substrates can lead to defects such as blistering and delamination. It identifies the underlying causes, including water-soluble contaminants and inadequate moisture control, and outlines methods for diagnosis and prevention. The document also provides practical guidance on design, installation, and remediation strategies to minimise the risk of osmotic failure and ensure long-term floor performance.
