Abstract
A prefabricated leave-in-place screed rail for use in forming a floor or pavement slab of slab material cast on opposite sides of the screed rail so that the slab material forms a bond with each side of the screed rail, has an upwardly open groove extending along the rail between the sides. The groove provides for preferential cracking of the screed rail upon shrinkage of the slab material. The screed rail has a toughened upper layer adjacent each opposite side of the groove, and a sealant in the groove.
