A floor panel and a floating floor system include a top surface and a bottom surface. The top surface has a visible decorative pattern and the bottom surface has a recess which extends about the periphery of the bottom surface. The recess has a recess surface. The floor panel includes a joining member with a top surface and a bottom surface. The top surface of the joining member is adhered to the recess surface of the recess. The bottom surface of the joining member and the bottom surface of the floor panel are essentially flush which each other. The use of the joining member does not create any imprints on the top surface of the floor panel.
