Method and apparatus for two-lift concrete flatwork placement

Abstract:

A method of manufacturing a concrete substrate includes placing a first concrete layer on a support base configured to support the concrete substrate, positioning a concrete slab load transfer apparatus on a top surface of the first concrete layer, wherein the top surface of the first concrete layer supports the concrete slab load transfer apparatus, and placing a second concrete layer on the top surface of the first concrete layer such that the second concrete layer covers the concrete slab load apparatus.
