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 formed 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.

The apparatus of claim 1, wherein the first rod comprises a circular cross-section. 4. The apparatus of claim 1, wherein the first rod comprises a rectangular cross-section. 5. The apparatus of claim 1, wherein the second rod comprises a terminal end with an anchor. 6. The apparatus of claim 1, wherein the second rod comprises a circular cross-section. 7. The apparatus of claim 1, wherein, the top planar surface of the concrete housing is parallel to the bottom planar surface of the concrete housing. 8. The apparatus of claim 1, further comprising a sealant on the outer wall of the concrete housing. 9. The apparatus of claim 1, wherein the first protruding end and the second protruding end of the first rod situated external to the concrete housing are substantially flush with the top planar surface of the concrete housing. 10. The apparatus of claim 1, wherein the height of the concrete housing is the minimum height of the hole. 11. The apparatus of claim 1, further comprising a batch control number embossed on the concrete housing. 12. The apparatus of claim 1, further comprising a batch control number stamped on the concrete housing. 13. An apparatus for sealing a hole, comprising: a concrete housing configured to substantially seal a hole in a floor of a building;a first rod situated within the concrete housing, the first rod including a first protruding end and a second protruding end, each protruding from the concrete housing, wherein the first protruding end and the second protruding end are configured to register with one or more grooves on a surface of the floor adjacent to the hole; anda second rod coupled substantially perpendicular to the first rod, the second rod entirely embedded within the concrete housing, wherein the second rod is coupled to the first rod at a bent middle portion of the first rod. 14. The apparatus of claim 13, wherein the concrete housing includes a top planar surface, an outer wall, and a bottom planar surface that are integral to and unitarily form the concrete housing. 15. The apparatus of claim 14, wherein, the top planar surface of the concrete housing is parallel to the bottom planar surface of the concrete housing. 16. The apparatus of claim 14, further comprising a sealant on the outer wall of the concrete housing. 17. The apparatus of claim 14, wherein the first protruding end and the second protruding end of the first rod situated external to the concrete housing are substantially flush with the top planar surface of the concrete housing. 18. The apparatus of claim 14, wherein the concrete housing is cylindrically shaped and tapers inward.
