ABSTRACT:
A floating screed device has a first section for cutting through plastic concrete and a second section for floating on the plastic concrete. The first and second sections are coupled together by a mechanism that moves the first section relative to the second section in a direction perpendicular to the planar bottom of the second section as the floating screed device is moved through a volume of unfinished plastic concrete.
