(57) A method of laying one or more concrete topping slabs over an existing concrete structure includes providing a concrete form defining an area on a surface of the concrete structure, drilling a hole into the surface of the concrete structure within the area, the hole being closer to a first border of the concrete form than to a second border of the concrete form opposite the first border, attaching first and second slip-dowel receiving sheaths respectively to the first and second borders, securing a first end portion of a bent metal bar in the hole with a second end portion of the bent metal bar extending parallel to the surface and the slip-dowel receiv­ing sheaths toward the second border, and pouring a concrete mixture over the surface of the concrete structure and about the first and second slip-dowel receiving sheaths and the second end portion of the bent metal bar.
