ABSTRACT:
First and second cast-in-place concrete slabs are maintained in alignment by cutting a semi-circular groove in an edge surface of the first formed slab, positioning a flat rectangular dowel within the groove so that the dowel extends outwardly from the edge surface, and then casting the second slab against the edge surface to embed the dowel within the second slab. A gasket is engaged with the dowel to seal the groove against the intrusion of fluid concrete as the second cast-in-place. The gasket also serves to space the dowel from the groove to accommodate limited lateral movement of the dowel and groove relative to one another.
