A construction method of a flooring material formed of a PLA resin, comprising:

• making construction floor even and removing foreign substances;
• applying an adhesive on the construction floor;
• attaching tiles consisting of a bottom layer, a base layer, a dimensionally stabilizing layer, a balance layer, a printed layer, a transparent layer and protective layer which are formed of the PLA resin and stacked in turn, such that the tiles are arranged to be spaced apart from each other with a gap therebetween;
• and
• forming a construction joint at the gap between the tiles.
