If a tile is not quite flat extra care must be taken when laying to avoid lipping. Simply put the tiles are set at different levels meaning that they are spaced evenly in width but not in height. Unfortunately with such dramatic eye appeal comes the risk of lippage the difference in height between the.

For a paver tile commonly used on floors the allowable warpage is defined as follows. When measured as described in astm c 485 the warpage of each tile in the sample shall not exceed 1 0 percent along any edge nor 0 75 percent on either diagonal.
