The answer is yes. The force-bearing area of the big size tiles is very large. It must be ensured that the big size tiles are flat when paving and cannot be different in height. In addition, the big size tiles must be fully combined with the tile glue, otherwise unevenness or hollowing will occur. It is fatal for paving. Lay the tiles evenly on the base layer, and use a vibrator to beat the tiles to make it easy to discharge air bubbles and increase the full grout rate at the bottom of the tiles to avoid hollowing. Use a vibrator to flatten the tile surface and measure it with a level to ensure that the tiles are laid horizontally.
