A screed support and method for screeding cement comprises digging a plurality of arranged holes in the bed surface of the area to be cemented. Unsolidified cement is poured into each of the holes, a hollow sleeve is inserted into the wet cement and positioned therein in a substantially vertical orientation, and the cement is cured to a solidified state. A rail support member having a threaded rod and a mating, adjustable collar, is telescopically inserted into each of the sleeves. Screed support rails are connected with each rod, and the elevation and inclination of the same is adjusted in infinitely small increments by manipulating each collar in accordance with the desired, predetermined requirements. Additional unsolidified cement is then poured between the rails, and a self-propelled screeding machine is passed thereover to smoothen and level the uneven free surface of the additional cement. Before the additional cement hardens, the rails are disconnected from the support members and the collar and rod assemblies are extracted from the sleeves.
