Abstract
Laying floor tiles is more convenient because the floor tiles are provided with tongues which can be fitted readily into grooves in adjacent tiles because the depth of each groove is less than the magnitude of the portion of a tile which is overhanging a portion of the adjacent tile. Such overhanging and underfitting relationships supplement tongues along adjacent sides into grooves of two adjacent tiles. Peripheral floor tiles can be anchored, but central area tiles can be free from the conventional adhesion to the subflooring. Venting for moisture equilibration between the atmosphere and a sub-flooring such as a concrete slab is achieved because of the absence of adhesive between vertical walls of adjacent tiles.
