Description: Question: What does it mean when a packaged repair material is labeled as shrinkage-compensating or nonshrink?

Answer: The terms 'shrinkage-compensating' and 'nonshrink' are both intended to describe materials that exhibit no or little net contraction as a result of shrinkage. In practice, however, these terms are of limited use in the selection of repair materials without supporting test data on time-dependent volume changes.
