The moisture, which works their way up from the earth in concrete on and felow grade, is inclined prevent or destroy satisfactory bonding of adhesives by shear physical displacement. This report describes that (1) warping and floating of plastic floor tiles mainly cause by absorbing or removing moisture, (2) these displacements are influenced by amounts of ground moisture and the variety of tiles, and (3) necessary bonding stress to fix floor tiles could be estimated by geometrical analysis of warping of them.
