A machine for compacting and leveling a poured floor covering. The machine includes a frame having a pair of side members and a pair of parallel, ground engaging, cylindrical rollers rotatably supported on the side members and supporting the frame for movement in forward and reverse directions. A screw member is rotatably supported on the side members and has a right-hand screw segment over a portion of the length thereof and a left-hand screw segment over a remainder portion of the length thereof. If desired, a second screw member, a trowelling mechanism and a vibratory mechanism, can be provided. Structure is provided on the front screw member for pushing the material arriving at the region between the screw segments forwardly of the machine, the leveled material passing under the screw member, as the machine is moved forwardly, being compacted by successive passage beneath the cylindrical rollers.
