US Patent:

20170370115, Dec 28, 2017

Filed:

Aug 10, 2017

Appl. No.:

15/674404

Inventors:

Gerald R. Gray - Costa Mesa CA, US
Robert W. Johnson - Costa Mesa CA, US

International Classification:

E04G 23/02

Abstract:

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.
