    If referring to the black plastic strip, its a cavity closer. If you remove it the cavity will be open . Not ideal for supporting a mat tho. If there's room for ply beneath the mat then you could create adequate support if not then an option is to remove it, line the cavity with a sheet of dpm (damp proof membrane), forming a continuous tray and then fill it with concrete/ screed. Without dpm then you will create a damp issue.
