## Background
This application claims the benefit of U.S. Provisional Application No. 60/945,457, filed Jun. 21, 2007, entitled “Veneers for Walls, Retaining Walls, Retaining Wall Blocks, and the Like”, the contents of which are hereby incorporated by reference herein.


FIELD OF THE INVENTION
This invention relates to veneers. In particular, the invention relates to veneers for walls, retaining walls, retaining wall blocks, and the like.
BACKGROUND OF THE INVENTION
Retaining walls are used in various landscaping projects and are available in a wide variety of styles. Numerous methods and materials exist for the construction of retaining walls. Such methods include the use of natural stone, poured concrete, precast panels, masonry, and landscape timbers or railroad ties.
A widely accepted method of construction of such walls is to dry stack concrete wall units, or blocks. These blocks are popular because they are mass produced and, consequently, relatively inexpensive. They are structurally sound, easy and relatively inexpensive to install. Because they comprise concrete, they are durable. They can be given a desired appearance, such as, for example, natural stone. Many block systems also use pins that are adapted to fit in corresponding pin holes in adjacent blocks or may use other mechanical means to contribute to the stability of a wall.
Typically, retaining wall blocks are manufactured to have the desired appearance on the front face (i.e., the outer face of a wall) because only the front is visible after the wall is constructed. It is highly desirable to have the front face of the wall system have a natural stone appearance, and many approaches are used in the art to treat or process concrete to evoke the appearance of natural stone, including splitting the block, tumbling the block to weather the face and edges of the face, and using processing or texturing equipment to impart a weathered look to the concrete.
Depending upon their location, the soil type, the amount of water that can flow through the wall, and the mineral content of the water, an undesirable appearance can develop on the surface of a retaining wall. In addition, due to exposure to the elements and freeze/thaw cycles, concrete retaining walls may exhibit spalling, that is, chipping and cracking of concrete, which affects their appearance and can ultimately affect their utility. Freeze-thaw effects are worsened when the wall face is exposed to salt spray, which commonly occurs on roadways where de-icing salts are used to clear the road of ice and snow. Efflorescence refers to the leaching of mineral salts from water and this often occurs on walls in contact with water. The resultant deposit on a surface creates an unattractive white stained appearance on a wall.
There have been prior efforts to add a veneer to regular and segmental retaining walls with natural stone or concrete that is pre-cast molded to closely resemble natural stone. While such veneering produces aesthetically pleasing walls, it is a laborious and highly expensive process, as it requires skilled masonry work to tie in the stone or concrete veneer to the wall using traditional mortared masonry construction methods. Such veneering can double the cost of the finished wall. In addition, segmental retaining walls are not rigid structures and applying a rigid mortared veneer may cause cracking unless appropriate steps are taken to provide slip joints that allow for such movement. Veneers for retaining walls are described in US 2005/0252144 A1, the contents of which are incorporated by reference herein.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In this application, “wall” can refer to structures comprising natural stone, poured concrete, precast panels, masonry, landscape timbers or railroad ties, retaining wall blocks, and exterior and interior walls of buildings. Veneers are attached to the exposed surfaces of a wall.
In one embodiment of the invention, the veneers are used with retaining walls, and in a preferred embodiment, the retaining walls comprise blocks. The retaining wall blocks can be made of a rugged, weather resistant material, preferably (and typically) zero-slump molded concrete. Other suitable materials include polymers, composite materials with reinforced fibers, wood, metal, stone, etc. The blocks may have various shapes and characteristics, as known in the art, and may be stacked one upon the other to provide a vertically straight wall, and also may be stacked so that they are angled or set back from vertical. As known in the art, the blocks may be connected to each other by a pin attachment system, or the blocks may be provided with one or more protruding elements that interlock with one or more corresponding recesses in an adjacent block. Blocks that can be used with the veneers of the invention are described in U.S. patent application Ser. No. 12/124,311, filed May 21, 2008, entitled “Wall Block and Wall Block System for Constructing Walls”, the contents of which are hereby incorporated by reference herein.
“Upper” and “lower” refer to the placement of the block in a retaining wall. The lower, or bottom, surface is placed such that it faces the ground. In a retaining wall, one row of blocks is laid down, forming a course. An upper course is formed on top of this lower course by positioning the lower surface of one block on the upper surface of another block.
Retaining walls may be straight (i.e., substantially linear, as well as vertically straight), curved (concave, convex, or serpentine) or may have sharp corners (i.e., 90 degree angles). Such walls can be angled from vertical. Reinforcing geogrid tie-backs or geosynthetic fabrics (also referred to generally as geogrids and geotextiles) may be used with retaining wall blocks.
The veneers are produced in dimensions that are convenient to manufacture and handle. Convenient veneer sizes are about 4×12 inches (10×30 cm), 6×16 inches (15×41 cm), 8×18 inches (20.5 cm×45.7 cm), 16×48 inches (40.6×121.9 cm), 32×48 inches (81.3×121.9 cm), 2 feet by 4 feet (61×122 cm), 4 feet by 8 feet (122×244 cm), and 2 feet by 8 feet (61×244 cm). The larger veneers preferably are made of polymers, especially polymers including fiberglass, etc. The dimensions of the veneer may vary from these stated dimensions in order to meet aesthetic or functional requirements of particular applications.
The back of the veneer is provided with an attachment means so that the veneer can be affixed to a wall or retaining wall block. If the veneer is made of plastic, a desired attachment means can be molded into the panel when it is formed. The desired attachment means can be attached by adhesive or attached by mechanical means such as screws and bolts. Attachment means include hooks, brackets, connection joints, connection channels, and the like. Preferred attachment mechanisms are described further below.
The invention provides several different embodiments using veneers, including those listed below.
(1) Pre-cast Concrete Veneer Facing Attached to a Dry Cast Concrete Support Block
In one embodiment, a pre-cast concrete veneer facing is attached to a dry cast concrete support block with a connection device. Connection slots are molded into the block.
(2) Pre-cast Concrete Veneer Facing Attached to a Wet Cast Concrete Support Block
In another embodiment, a pre-cast concrete veneer facing is attached to a wet cast concrete support block by integral cast.
(3) Real Stone Veneer Facing Attached to a Dry Cast Concrete Support Block
In another embodiment, a real stone veneer facing is attached to a dry cast concrete block with a connection device. Connection slots are molded into the block. Real stone veneers are typically constructed by attaching stones into a plastic support tray. The tray with the stones then becomes the real stone veneer.
Stone has good compression qualities but is weak in tension. The stone is quite brittle by itself because it usually is thin in section to minimize the weight and cost of the stone. The plastic support tray acts as the tensile element. Once they are glued together, the stone and support tray from a “stressed skin” or diaphragm structure, where they combine the compression and tension elements to form a strong structure.
(4) Real Stone Veneer Facing Attached to a Wet Cast Concrete Support Block
In one embodiment, a real stone veneer facing is attached to a wet cast concrete support block by integral cast.
(5) Polymer Veneer Facing Attached to a Dry Cast Concrete Support Block
In another embodiment, a polymer veneer is attached to a dry cast concrete support block with a connection device. Connection slots are molded into the block. In one embodiment, the polymer veneer has the appearance of stone or rock.
(6) Polymer Veneer Facing Attached to a Wet Cast Concrete Support Block
In one embodiment, a polymer veneer facing is attached to a wet cast concrete support block by integral cast. In one embodiment, the polymer veneer has the appearance of stone or rock.
(7) Polymer Panels Attached to Wall of Retaining Wall Blocks
In one embodiment, polymer panels are attached to a wall made of retaining wall blocks having non-textured smooth faces. The polymer panels are attached with separate connection devices. The panels have integral connection attachment points or attachment devices. The polymer panels are larger than the individual retaining wall blocks. In one embodiment, the individual retaining wall blocks are aligned and the larger veneers are slid into the retaining wall blocks. The veneers can also vary in size in a single wall.
(8) Polymer Pieces Used to Build Veneers On Any Structure
In one embodiment, polymer pieces can be used as individual elements to build veneers on almost any interior or exterior structure.
(9) Exterior or Interior Siding Veneers
In one embodiment, exterior or interior siding veneers can be used on exterior or interior walls. The veneers could be tile, brick, stone, polymer made to look like stone, etc.
Additional embodiments are described herein.
The veneers of the invention can comprise a mineral aggregate in fiberglass. This material is produced by mixing stone particles, sand, or mineral with resin, and pouring this mixture into a mold. Typically, particles of the type of stone that the veneer is meant to resemble are used in the resin mixture, and these particles provide the color for the veneer. For example, if the veneer is intended to resemble natural granite, then granite particles are used in the mix. If limestone is the desired look, then fine particles of limestone may be used. Various powdered pigments may be added to the mix in order to create different colors or shades of color. The mold is configured to impart a surface texture to the material that resembles the texture of natural stone. After the mineral resin mix is added and spread across the mold, a mixture of glass fibers and resin is added to the back side of the intended object in the mold. At this stage, structural components used to attach the veneer to the surface that is being veneered may be added. Such components may be formed of pultruded fiberglass, and may be attached to the veneer during the curing process in order to create a bond between the veneer and the structural component. After the resin has cured, the front surface of the veneer preferably is sandblasted to remove resin from the surface, thus revealing a naturally-appearing mineral or stone surface. Alternatively, the front surface may by polished in order to produce a polished stone look. Veneers of different colors can be combined to form an aesthetically pleasing wall.

The retaining wall block 210 can be made of any appropriate material. Appropriate materials include wet cast concrete, dry cast concrete, plastic, etc. The veneer 220 can be made of any appropriate material. Appropriate materials include a pre-cast concrete veneer, polymer veneer, real stone veneer, etc. The block 210 and veneer 220 can be used to build a retaining wall as described above in the description of FIG. 2.
FIG. 7 shows a veneer 320 made of real stone. Veneer 320 has front face 325 and veneer connection portions 350. Veneer connection portions 350 are attached to tray 335. In FIG. 7 the stones 345 are shown offset from the tray 335. The stones 345 have not yet been attached to the tray 335. Real stones 345 are attached to the tray 335, using an appropriate adhesive. Appropriate adhesives include epoxy, polyurethane adhesives, methacrylate adhesives, etc. The real stones 345 preferably are 0.75 inch (1.9 cm) to 1 inch (2.5 cm) thick. The veneer 320 preferably has front faces with dimensions of 12 inches (30 cm) in width by 4 inches (10 cm) in height, 16 inches (41 cm) in width by 6 inches (15 cm) in height, or 18 inches (46 cm) in width by 8 inches (20 cm) in height. The veneer 320 is attached to a retaining wall block and used as described herein. The veneer 320 can have a top lip or a top and bottom lip as described above in connection with FIGS. 3 to 6. The lips preferably are made of real stone. Natural stone is dense and generally heavy compared to polymers or fiberglass. Due to this a thin profile of stone is desired to minimize weight. A depth of 0.75 inch (1.9 cm) allows for depth of joints and stone character and provides pleasing aesthetics.
FIG. 8 shows a tray 435 having veneer connection portions 450. The tray 435 preferably is made of plastic. Tray 435 has holes 465 in the base 455 of the tray. Slots could also be used in place of holes 465 or a combination of holes and slots could be used. The tray 435 is used to hold real stones and make a veneer similar to that described above in connection with FIG. 7. The holes 465 help to strengthen the attachment of the veneer to the tray because they allow adhesive to form a better attachment to the tray than a tray with just a flat base. Instead of holes, the tray could have wells to contain adhesive. The holes/slots 465 can be tapered such that the set adhesive locks into the tray and cannot pull out in a forward direction toward the veneer.
Holes allow adhesive to seep through the tray. When the adhesive has set and hardened, the stone is attached to the adhesive and the adhesive is mechanically prohibited from pulling through the holes in the tray. This attachment is somewhat like a riveted connection. This is significant because most adhesives do not bond well to a polymer tray.
FIG. 9 shows a portion of a tray 535 similar to the tray of FIG. 8. The tray 535 has a raised honeycomb structure 575 that acts as strength ribs to add greater support to the veneer tray.
