Vapor and termite barrier and method for concrete slab construction

摘要

A vapor and termite barrier and method for use in concrete slab construction includes applying an elastomeric-seal fluid in a liquid state that cures into an elastomeric seal of all ground surface, reinforcement, conduits and concrete on a slab area. A method for applying the elastomeric-seal fluid is preferably spraying, but can include pouring, hosing and dumping. The elastomeric-seal fluid can include a mixture of germicide grade of chemical, such as boron, and a conventional product that is preferably white and has a consistency that is produced commercially for tops of house trailers and motor homes. Preventing runoff of the elastomeric-seal fluid before it cures into the elastomeric seal can be provided by a preparation step of eliminating excessive ground porosity and providing slab-area walls to a height necessary to contain the elastomeric-seal fluid at a rate that it is applied before it cures. Depth of the elastomeric-seal fluid can be ten to twenty mills, depending on consistency of the product. A highest preferred consistency of the product mixed with about one-fourth boron can be applied for a depth of about ten to twenty mills. Pouring concrete after applying the elastomeric-seal fluid and allowing it to cure for two-to-four hours, depending on weather and on product consistency, then can proceed more rapidly with less risk of damage to its protective barrier than for pouring concrete onto conventional plastic material.
