1. A method of laying one or more concrete topping slabs over an existing concrete structure, the method comprising:
providing a concrete form defining an area on a surface of the concrete structure;
drilling a plurality of holes into the surface of the concrete structure within the area;
attaching a slip-dowel receiving sheath to the concrete form, the slip-dowel receiving sheath extending parallel to the surface of the concrete structure along an axis;
inserting a plurality of bent metal bars into respective ones of the plurality of holes such that a first end portion of each bent metal bar is received in the respective one of the plurality of holes and a second end portion of each bent metal bar extends in a common direction parallel to the axis; and
pouring a concrete mixture over the surface of the concrete structure and about the slip-dowel receiving sheath and the second end portions of the plurality of bent metal bars.
