The present apparatus and method relates in general to sealing a hole in a floor with a precast plug. A precast plug is created by pouring a wet aggregate mix into a form mold and thereafter inserting a pre bent rod into the uncured mixture, positioning it such that the center of the rod rests in the center of the form mold and the ends of the rod extend outward near the top of the form mold. The mix is then cured. The precast plug may then be transported to the hole that it is destined to fix. Grooves may be carved on either side of the hole to accommodate the rod's ends. The interior of the hole and the exterior of the plug may then be covered with a sealant, after which the plug may be inserted into the hole. Once the sealant cures, the hole is fully repaired.

1. An apparatus for sealing a hole in a floor comprising: a concrete housing; anda plurality of rods, each rod partially situated immediately below a top planar surface of the concrete housing including a middle portion and distal ends, the middle portion of each rod embedded within the concrete housing, the distal ends of each rod situated external to the concrete housing and substantially flush with the top planar surface, wherein the plurality of rods are parallel to each other and configured to register with grooves adjacent to the hole. 2. The apparatus of claim 1, wherein the middle portion of each rod is bent to form a c-shape between the distal ends of each rod, the c-shape entirely embedded within the concrete housing. 3. The apparatus of claim 1, wherein the concrete housing includes the top planar surface, an outer wall, and a bottom planar surface that are integral to and unitarily form the concrete housing. 4. The apparatus of claim 3, wherein, the top planar surface of the concrete housing is parallel to the bottom planar surface of the concrete housing. 5. The apparatus of claim 1, wherein the concrete housing is cylindrically shaped and tapers inward. 6. The apparatus of claim 1, wherein at least one rod is comprised of steel. 7. The apparatus of claim 1, wherein at least one rod is comprised of plastic. 8. The apparatus of claim 1, wherein at least one rod is comprised of wood. 9. The apparatus of claim 1, wherein at least one rod is comprised of composite materials. 10. The apparatus of claim 1, further comprising a logo and a size indicator embossed on the concrete housing. 11. The apparatus of claim 1, further comprising a logo and a size indicator stamped on the concrete housing. 12. An apparatus for sealing a hole in a floor comprising: a concrete housing including a top planar surface, an outer wall, and a bottom planar surface that are integral to and unitarily form the concrete housing, wherein the top planar surface of the concrete housing is parallel to the bottom planar surface of the concrete housing; anda plurality of rods, each rod including a middle portion and distal ends, the middle portion of each rod bent to form a c-shape between the distal ends of each rod, the c-shape entirely embedded within the concrete housing, and the distal ends of each rod situated external to the concrete housing, wherein the plurality of rods are parallel to each other and configured to register with grooves adjacent to the hole. 13. The apparatus of claim 12, wherein the distal ends of each rod situated external to the concrete housing are substantially flush with the top planar surface of the concrete housing. 14. The apparatus of claim 12, wherein the concrete housing is cylindrically shaped and tapers inward. 15. The apparatus of claim 12, wherein at least one rod is comprised of steel. 16. The apparatus of claim 12, wherein at least one rod is comprised of plastic. 17. The apparatus of claim 12, wherein at least one rod is comprised of wood. 18. The apparatus of claim 12, wherein at least one rod is comprised of composite materials. 19. An apparatus for sealing a hole in a floor comprising: a cylindrical concrete housing including a top planar surface, an outer wall, and a bottom planar surface that are integral to and unitarily form the concrete housing, wherein the top planar surface of the concrete housing is parallel to the bottom planar surface of the concrete housing; anda plurality of steel rods, each rod including a middle portion and distal ends, the middle portion of each rod bent to form a c-shape between the distal ends of each rod, the c-shape entirely embedded within the concrete housing, the distal ends of each rod situated external to the concrete housing and substantially flush with the top planar surface of the concrete housing, wherein the plurality of rods are parallel to each other and configured to register with grooves adjacent to the hole.
