Abstract:
The present invention is directed to a Concrete Decorative Inlay Process where the concrete slab is initially poured with a recessed section constructed with a rough broom finish on the bottom. After curing a bonding agent is applied and an artistic form is located on the depressed area and additional concrete, possibly of different colors or textures to enhance the design, is poured into the design cavity and a variety of decorative elements are inlayed this area. After the design area has cured the artistic form is removed and the recessed area is then filled in, possibly with still a different color or texture of concrete to finish the project. This allows ample time to work in close proximity to the design area and the ability of using different elements to enhance the design.

Description:
FIELD OF THE INVENTION 
     This application provides a unique process of inlaying decorative elements into the finished surface of concrete during the initial construction processes. 
     BACKGROUND OF THE INVENTION 
     There is a growing need for quickly and easily inlaying decorative materials within artistic designs in concrete during the construction process. Too often when these designs are attempted they are rough, the edges where the materials meet are uneven, the decorative materials tend to release and come out during climate changes and the complete designs do not have a professional finished appearance that the artist has desired. The artists that create the designs are not normally capable of getting out on the wet concrete to actually create the finished product and will rely upon the concrete finishers to duplicate the artistic rendering they had created. This generally ends up being not quite what the artist had in mind. Additionally the drying time of concrete is relatively short which often limits the time to inlay the decorative elements while completing the surface finishing processes. 
     Numerous innovations for providing decorative patterns on a variety of surfaces have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present design as hereinafter contrasted. The following is a summary of those prior art patents most relevant to this application at hand, as well as a description outlining the difference between the features of the Concrete Decorative Inlay Process and the prior art. 
     U.S. Pat. No. 7,493,732 of Robin Brailsford et al. describes a mosaic concrete product, methods of creating the same, and methods of fabricating a module for use in creating the mosaic are provided. The methods of installing the mosaic upon an uncured concrete surface utilize the module. The module may be fabricated by mapping out tile in a design corresponding to the mosaic adhering the tile to a template utilizing an adhesive, the tile being positioned thereon corresponding to the design; and allowing the adhesive to set. The module may define upper and lower surfaces; the upper surface including the tile adhered thereto. The methods of installing the mosaic comprises: positioning the module upon the uncured concrete surface; embedding the tile into the concrete surface; massaging the tile into the concrete surface to interpose a quantity of cement/fines paste between the adjacent tiles; and finishing the concrete surface. 
     This patent describes a process of adhering mosaic tiles to a template of paper or a mesh utilizing an adhesive. The paper is to be placed on top of the wet concrete and the mesh to be imbedded into the concrete. This provides a limited time to work on the project. When using the paper the concrete has to set enough to hold the mosaic tiles and the adhesive has to release from the tiles in time to finish the concrete around the design. Depending upon the ambient temperature this can create a very limited working time. When the tiles on the mesh are imbedded in the wet concrete slab there will not be any concrete around the design that will enhance the design with color or texture. This process does not depict the unique features of the Concrete Decorative Inlay Process where design patterns are inlayed in concrete slabs. 
     U.S. Pat. No. 4,217,740 of Philip N. Assanti a variable mosaic pattern formed from interfitting blocks formed into standard shape is disclosed groups with curved or serpentine shapes. Interchangeability of the groups of the standard shapes permits easy installation, and production machinery presently available permits low cost manufacturing of the interchangeable components, which can be made of a suitable plastic molded from suitably shaped molds or stamped out on presses, cut from slabs of stone, or formed by other suitable means. The interchangeable components can be assembled indefinitely in any direction in an ever-changing mosaic pattern creating a random decorative effect. 
     This patent describes a variable mosaic pattern formed from interfitting blocks formed into standard shape and does not depict the unique features of the Concrete Decorative Inlay Process where design patterns are inlayed in concrete slabs. 
     U.S. Pat. No. 5,398,458 of Lars E. Henriksen describes an invention that generally relates to a process of and apparatus for manufacturing tile mosaics from at least two stone slabs, such as marble or granite slabs. The process comprises the steps of: a) cutting each of the two slabs into a matrix of pieces while maintaining the original orientation of the pieces, b) classifying the pieces of each matrix into two or more sets of pieces, c) intermixing a first set of pieces of one slab with a second set of pieces of another slab while maintaining the original orientation of the pieces, thereby forming the mosaic. The cutting apparatus comprises: a) a platen having a resilient layer for supporting the slab, b) a gantry table saw having a plurality of blades and a rotatable table for supporting the platen, and c) a hold-down rack for securing the slab and platen during cutting. At least two grippers are used to intermix at least one set of pieces from one slab with at least one set of pieces from a second slab to form the mosaic. By mixing the color shades and grain patterns of several different stone slabs, a mosaic having a handset look is achieved. Adjacent rows of the newly formed mosaic matrix may be offset to further enhance the handcrafted appearance of the mosaic. 
     This patent describes an invention that generally relates to an apparatus for manufacturing tile mosaics from at least two stone slabs, such as marble or granite slabs and does not depict the unique features of the Concrete Decorative Inlay Process where design patterns are inlayed in concrete slabs. 
     U.S. Pat. No. 5,470,623 of Jacques Lucas tells of a device making it possible to install tiles or any other decorative design in the form of a panel, particularly on walls or floors, wherein these decorative designs are laid down and adhere by adhesive pre-bonding on a mesh consisting of a trellis of filaments, the said panels are formed of two parts, an external polygon consisting of mosaics arranged in rigorously defined positions which determine the manner in which the panels fit together, and a random arrangement inside the said polygon or frame with a density of mosaics or stones such that they do not touch and do not form any alignment, the juxtaposition of the said panels formed in this way provides a final appearance devoid of connection joint lines. 
     This patent tells of a device making it possible to install tiles or any other decorative design in the form of a panel. This patent is very similar to that of U.S. Pat. No. 7,493,732 of Robin Brailsford et al, but does not provide the extended working time or the benefit of accenting colors or textures around the central design area. 
     U.S. Pat. No. 6,033,146 of Lee Shaw et al, tells of a surface seeded exposed particulate concrete called Glass Chip Lithocrete being method of use includes use of small particulates, the particulates not necessarily chemically inert in the concrete mixture. The particulates are broadcast over the tipper surface of the concrete, and mixed into the cement paste derived from the concrete matrix by floats and finished by hand sponging. A surface retarder and vapor barrier are applied, and washing and curing operations follow. The present invention adds a chemical treatment of hydrolyzed alkali silica solution, preferably lithium quartz, penetrating the upper surface of the concrete mixture with minerals and silicates within the concrete mix. The resultant exposed particulate concrete has extreme flatness and high wear resistance suitable for high-traffic flooring applications, aesthetics resembling terrazzo or ceramic tile at a fraction of the price, and the strength and resistance to corrosion expected of concrete surfaces. 
     This patent tells of a surface seeded exposed particulate concrete called Glass Chip Lithocrete but does not depict the unique features of the Concrete Decorative Inlay Process where design patterns are inlayed in concrete slabs. 
     None of these previous efforts, however, provides the benefits attendant with the Concrete Decorative Inlay Process. The present design achieves its intended purposes, objects and advantages over the prior art processes through a new, useful and unobvious combination of method steps and component elements by employing readily available materials. 
     In this respect, before explaining at least one embodiment of the Concrete Decorative Inlay Process in detail it is to be understood that the design is not limited in its application to the details of construction and to the arrangement, of the components set forth in the following description or illustrated in the drawings. The Concrete Decorative Inlay Process is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for designing of other structures, methods and systems for carrying out the several purposes of the present design. It is important, therefore, that the claims be regarded as including such equivalent construction insofar as they do not depart from the spirit and scope of the present application. 
     SUMMARY OF THE INVENTION 
     The principal advantage of the Concrete Decorative Inlay Process is that the design area can easily be worked on separately after the complete concrete slab has partially cured. 
     Another advantage of the Concrete Decorative Inlay Process is that a decorative recessed area around the central design can be filled with a different colored or texture to enhance the central design feature. 
     Another advantage of the Concrete Decorative Inlay Process is that the design template can be cut by the artist at a separate location. 
     Another advantage of the Concrete Decorative Inlay Process is that there is not the limited time required to create the design as there is in other design projects. 
     These together with other advantages of the Concrete Decorative Inlay Process along with the various features of novelty, which characterize the design, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. 
     The initial preparation for the preferred embodiment of the Concrete Decorative Inlay Process is to compact the substrate to 90-95% compaction and form the outer perimeter area and install reinforcement wire mesh or rebar as required. Form the recessed design area, and install the concrete to the form height, with the recessed design area having a heavy broom finish. Allow the perimeter area to cure enough to be walked on allowing the workers to work closely to the design areas. 
     Install foam template or compressed board as per Artist and Architect&#39;s rendering and coat the broom finish on the recessed design area with a bonding agent. Place concrete within the foam template or compressed board design with a plus or minus 2 inch to 4 inch special concrete mix with a ⅜ inch or 1 inch mix and added in shrinkage reducer. A wide variety of design elements can easily be inlayed into the surface of the concrete to create a tessera finish such as, vitreous glass tile, aggregate rock, ceramic tile, ammonite fossils, glass baubles, and tumbled broken glass. Tamp and float the materials to required elevation and work cementations materials to ensure monolithic adhesion and apply the surface retarder as required. 
     When the surface has reached a reasonable cure then wash surface to remove cementations exposure over the design elements, a soft scrubber may be required. Continue power washing as necessary to the desired aesthetics and uniformity and remove the mold. Protect the tessera inlay and coat the remaining recessed area having a heavy broom finish with a bonding agent. Pour concrete in the depressed area around the raised design having the tessera inlay. This concrete may have a different color or surface texture to enhance the design features. Apply sealers when concrete has amply cured. 
     The preparation for the alternate embodiment of the Concrete Decorative Inlay Process will be to make designer templates of the outer contours of the desired design out of wood, composition or fiberglass approximately ½″ thick. The edges of these templates may be squared or have a beveled edge to facilitate in the removal process. Prepare sub-grade to a 90%-95% compaction and form the outer perimeter area installing reinforcement wire mesh or rebar as required. Place minimum of 2″ sand in form work to ensure ample bleeding once concrete has been placed and install form members and reinforcement set to desired depth, depending on thickness of concrete being placed. 
     Install concrete within the formed area and screed, tamp and float in the conventional manner. Seed aggregate into wet concrete if aggregate finish is required. Optional finishes can be acid etch or acid stains, sand finish, hard trowel, stamped textures or colored concrete. All may be used to enhance and compliment the architectural or artist&#39;s design. 
     While the concrete is still wet settle the designer templates into the wet concrete in the desired location. Finish surface elevation around the designer template tamping and floating cementatious materials in and around template insuring ample consolidation embedding aggregate uniformly into the fines and cement paste. Apply retarder by working with soft broom and install cure blanket to insure slowing curing procedure. 
     Once concrete has cured, wash slab and remove designer templates. Using a thin set or grout mixture, place inset tessera materials such as aggregate rock, ceramic tile, ammonite fossils, Glass bobbles or tumbled broken glass into desired location. Tamp and float tessera surface into position again to insure all particles fully embedded. The thin set or grout material may also be colored to enhance the Tessera design features. Apply retarder. Wash off concrete films to desire exposure. Once fully cured apply sealers and densifying agents. 
     Wet Set 
     The preparation for the second alternate embodiment of the Concrete Decorative Inlay Process will be to make flexible designer templates of a material like Mylar or Plexiglas and select all materials to be placed in artist&#39;s reproduction stencil. Place a minimum of 2″ of sand to ensure ample bleeding once concrete has been placed and install form members and reinforcement, set to desired depth depending on thickness of concrete being placed. 
     Install concrete within the formed area and screed, tamp and float in the conventional manner. Seed aggregate into wet cement if aggregate finish is required or use an acid etch, acid stains, sand finish, hard trowel, stamped textures or colored concrete. All may be used to enhance and compliment the architectural or artist&#39;s design. 
     Once surface is satisfactorily floated and the concrete has achieved a partial cure, lay out stencils in the desired location. Using outline within the stencil, begin inlaying the desired tessera material in place and tamp to the level of the template. Remove stencil and begin tamping the surface of the concrete to proper elevation. Floating in circular motion will work the concrete paste and fines into voids creating a monolithic bond. Apply retarder. Wash off concrete films to desire exposure. Once fully cured apply sealers and densifying agents. 
     The foregoing has outlined rather broadly the more pertinent and important features of the present Concrete Decorative Inlay Process in order that the detailed description of the application that follows may be better understood so that the present contribution to the art may be more fully appreciated. Additional features of the design will be described hereinafter which form the subject of the claims of this disclosure. It should be appreciated by those skilled in the art that the conception and the disclosed specific embodiment may be readily utilized as a basis for modifying or designing other structures and methods for carrying out the same purposes of the present design. It should also be realized by those skilled in the art that such equivalent constructions and methods do not depart from the spirit and scope of this application as set forth in the appended claims.
