     DETAILED DESCRIPTION 
     Provided herein are modular curbs for transitioning between wall and floor. In particular, curbs are provided seal gaps between the wall and floor, protect walls against impact, are waterproof, and protect against bacteria/mold infiltration. 
     Provided herein are curbs for the protection of structural surfaces, equipment, machinery, and users thereof. In some embodiments, curbs are secured to a structural surface, such as a wall, divider, or door opening frame, as well as to a floor (or ceiling) and bridge the gap therebetween. In some embodiments, the curbs provide a transition between a vertical structural surface (e.g., wall, wall panel, etc.) and a horizontal floor surface. In some embodiments, the curb prevents collection and/or invasion of water, mold/bacteria, etc. at the intersection (or a gap) between the vertical structural surface and the horizontal floor surface. In some embodiments, the curb is impregnated or back-filled with a filler material (e.g., concrete, cement, foam, etc.). In some embodiments, the curb is sealed to the floor (e.g., with silicone, with glue, with sealant, with a chemical weld, etc.). In some embodiments, the curb is sealed to a vertical structure (e.g., wall, door frame, wall liner, panel, etc.) by any suitable material (e.g., with silicone, with glue, with sealant, with a chemical weld, etc.). In some embodiments, the filler (e.g., behind and/or within the curb) is sealed to the floor and/or vertical structure (e.g., wall, door frame, wall liner, panel, etc.) by any suitable material (e.g., with silicone, with glue, with sealant, with a chemical weld, etc.). In some embodiments, the filler (e.g., behind and/or within the curb) is anchored to the floor and/or vertical structure (e.g., wall, door frame, wall liner, panel, etc.) by a mechanical anchoring element (e.g., screw, pin, etc.). In some embodiments, gaps between the curb and the floor are sealed/filled/closed by a sealant or chemical weld. In some embodiments, gaps between the curb and the vertical structure (e.g., wall, door frame, wall liner, panel, etc.) are sealed/filled/closed by a sealant or chemical weld. 
     In some embodiments, a curb is a structural component configured to sit at the intersection of a vertical structure (e.g., wall, door frame, wall liner, panel, etc.) and the floor. In some embodiments, a curb comprises a head  10 , a face  20 , and a foot  30  ( FIG. 1 ). 
     In some embodiments,  FIGS. 1 and 2  depict cross-sectional views of exemplary curbs within the scope herein. In some embodiments,  FIG. 3  shows a perspective view of an exemplary curb. In some embodiments, the cross-sectional geometry (See, e.g.,  FIG. 2A-C ) extends the length of the curb ( FIG. 3 ). In some embodiments, a curb is up to 24 feet (or more) in length (e.g., 1 inch, 2 inches, 4 inches, 6 inches, 9 inches, 1 foot, 2 feet, 3 feet, 4 feet, 6 feet, 8 feet, 10 feet, 12 feet, 16 feet, 20 feet, 24 feet, or more, or ranges therebetween). In some embodiments, multiple curbs (e.g., 2, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, or more, or ranges therebetween) are assembled end-to-end to cover a length of wall/floor. In some embodiments, multiple curbs are adhered to one another (e.g., end-to-end) using a sealant, adhesive, or chemical weld. In some embodiments, the end of a curb is configured (e.g., tapered) to facilitate end-to-end engagement with an adjacent curb. 
     In some embodiments, the head  10  comprises a vertical engagement segment  12 , angled segment  15 , and head joint  18  ( FIG. 2 ). In some embodiments, the head joint  18  is a fixed angle. In some embodiments, the head  10  comprises a vertical engagement segment  12  which is a vertical portion at the rear of the curb, and serves as a point of contact between the curb  1  and the vertical structure (e.g., wall, door frame, wall liner, panel, etc.). In some embodiments, the head  10  comprises an angled segment  15  which oriented to angle downward at between 15° and 75° (e.g., 15°, 20°, 25° 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, or ranges therebetween) from vertical. In some embodiments, the head  10  comprises a head joint  18  that acts as a transition between the vertical engagement segment  12  and the angled segment  15 . In some embodiments, the vertical engagement segment  12  and the angled segment  15  are acutely oriented to one another. In some embodiments, the head joint  18  is the top of the curb  1 . In some embodiments, the head joint is a bend in the curb  1  between the vertical engagement segment  12  and the angled segment  15 .

In some embodiments, the angled segment  35  sits at the bottom of the face  20  and slopes outward from the vertical 10-45° (e.g., 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, or ranges therebetween). In some embodiments, the floor engagement segment  32  sits at the bottom of the angled segment  35  and is perpendicular to the vertical structure (e.g., wall, door frame, wall liner, panel, etc.). In some embodiments, the bottom locking segment  34  extends upward from the floor engagement segment  32  and facilitates holding he curb within the filler material. 
     The curbs described herein find use in providing a protective transition (e.g., protection from impact, from water damage, from bacteria/mold, etc.) between a vertical structure (e.g., wall, door frame, wall panel, etc.) and the floor. In some embodiments, provided herein are systems comprising the curbs described herein, a vertical structure, and a floor. Exemplary systems are depicted in  FIGS. 4 and 5 ; however, such exemplary systems are not limiting on the scope of embodiments herein. For example, the vertical structures depicted in  FIGS. 4 and 5  are walls comprising an interior material (e.g., insulation) and surface material (e.g., FRP panel); while such systems are within the scope herein, embodiments herein are not so limited. As described throughout, the curbs herein also find use with other structures (e.g., vertical, substantially vertical, about vertical, not vertical, etc.). Additionally, the particular curb configurations depicted in  FIGS. 4 and 5  (as well as the other figures) are not limiting. Other curb configurations (e.g., multiple internal locking segments, etc.) are within the scope herein. Further, the embodiments depicted in  FIGS. 4 and 5  comprise a particular scheme for attaching the curb to the wall and floor and for sealing gaps; other schemes utilizing different combinations of adhesives, sealants, chemical welds, etc. are within the scope herein.  FIGS. 4 and 5  provide illustrative examples that inform but do not limit embodiments with the scope herein. 
       FIG. 4  depicts an exemplary embodiment in which a curb provides a protective transition between a floor and wall that meet directly at a perpendicular angle. The vertical engagement segment of the curb sits against the wall surface and the floor engagement segment sits against the floor. At each point of contact between the curb and the wall or floor, an adhesive or other sealant (e.g., caulking compound, silicone, glue, etc.) adheres the curb to the wall/floor and provides a water proof and/or water resistant seal. In some embodiments, the void between the curb and the wall/floor is filled with a filler material that is suitable for the particular application (e.g., cement, concrete, foam, insulation, etc.). In some embodiments, the filler is adhered to the wall and/or floor by an adhesive or other sealant (e.g., caulking compound, silicone, glue, etc.). 
       FIG. 5  depicts an exemplary embodiment in which a curb provides a protective transition between a wall and a floor with a flooring surface (e.g., urethane flooring) applied to a subfloor (e.g., concrete floor). In some embodiments, such as the one depicted in  FIG. 5 , the edge of the floor is sloped or curved to rise up and meet the edge of the curb. In such embodiments, the engagement point, or gap (if one exists), between the curb and the flooring may be sealed with an adhesive or other sealant (e.g., caulking compound, silicone, glue, etc.) or with a chemical weld. In some embodiments, the engagement point between the filler and the flooring may be sealed with an adhesive or other sealant (e.g., caulking compound, silicone, glue, etc.) or with a chemical weld. 
     In the embodiment depicted in  FIG. 5 , the vertical engagement segment of the curb sits against the wall surface and the floor engagement segment sits against the top of the flooring and the filler. At each point of contact between the curb and the wall or floor, an adhesive or other sealant (e.g., caulking compound, silicone, glue, etc.) adheres the curb to the wall/floor and provides a water proof and/or water resistant seal. In some embodiments, the void between the curb and the wall/floor is filled with a filler material that is suitable for the particular application (e.g., cement, concrete, foam, insulation, etc.). In some embodiments, the filler is adhered to the wall and/or floor by an adhesive or other sealant (e.g., caulking compound, silicone, glue, etc.). 
     In some embodiments, a gap between the curb and the wall and/or floor is filled and/or sealed with a chemical weld (See, e.g., U.S. Pub No. 2016/0222263; U.S. Pub No. 2002/0114914, U.S. Pat. No. 5,810,956; each of which is herein incorporated by reference in its entirety; for examples of chemical welds and materials and methods suitable for making such welds; other technologies of chemical welding are understood in the art). In some embodiments, the top gap between the curb and the wall is chemically welded. In some embodiments, the bottom gap between the curb and the floor is chemically welded. 
     In some embodiments, an anchor (e.g., screw, pin, etc.) stabilizes the filler material (and the associated curb) to the floor (as depicted in  FIGS. 4 and 5 ). In other embodiments, an anchor (e.g., screw, pin, etc.) stabilizes the filler material (and the associated curb) to the wall. In some embodiments, a system comprises a single anchor. In some embodiments, a system comprises multiple (e.g., 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 16, 18, 20, 22, 24, or more or ranges therebetween) anchors along the length of a curb (e.g., one per cross-sectional segment). In some embodiments, a system comprises multiple wall anchors. 
     In some embodiments, the protective curbs herein are secured to structural surfaces (e.g., horizontal surface (e.g., floor, flooring, etc.), vertical surface (e.g., wall, wall panel, door frame, etc.)) by the compositions and methods described herein. In some embodiments, the void or cavity formed behind the curb is filled with a filler material (e.g., concrete, cement, insulation, foam, etc.). In some embodiments, the void behind the curb is filled after securing the curb to the structural surfaces. In other embodiments, all or a portion of the void behind the curb is filled with filler material (e.g., concrete, cement, insulation, foam, etc.) prior to placement of the curb. 
     In one embodiment, the curbs described herein transversely extend the length of the structural surface. Alternatively, in some embodiments one or more sections of curbs terminate at a desired distance for adequate protection. For example, a curb is configured along a door frame, ramp, or hallway and terminates at the end thereof. In some embodiments, the termination point of a curb is sharp, abrupt, gradual, sloped, or rounded. In some embodiments, a curb is configured to fit to an inside (e.g., 90°) or outside (e.g., 270°) corner of a wall. In some embodiment, one or more curbs (e.g., linked (e.g., sealed, welded, etc.) end to end) transversely extend a wall length (e.g., 2 feet, 4 feet, 6 feet, 8 feet, 10 feet, 15 feet, 20 feet, 25 feet, 30 feet, 40 feet, 50 feet, 60 feet, 70 feet, 80 feet, 90 feet, 100 feet, or more, or ranges therebetween). Other lengths and distances are contemplated beyond those disclosed herein in order to accommodate various wall and door way sizes and configurations. In many embodiments herein, the curbs are placed against the floor, although curbs may alternatively be configured for placement at the junction of any two structural surfaces. Curbs may be placed near the floor, on the middle of a structural surface, at the junction between a wall and the ceiling, or any other position along a structural surface. The structural surface may be an internal or external wall, a wall to wall corner, a door, a door frame, or like structure requiring impact protection. The structural surface can be made of cement, wood, glass, ceramics, metals, stone or aggregate concrete. In some embodiments, the curb is secured to the structural surface by one or more attachment members (e.g., pins, screws, etc.) or substances (e.g., chemical welds, sealants, glues, caulk, silicone, etc.). 
     In some embodiments, a curb comprises a plurality of protrusions extending into the cavity therein that facilitate tight interaction between the curb and the filler material. Alternatively, a curb may comprise grooves that receive the filler material and facilitate interaction. In some embodiments, protrusions and/or grooves form dovetails or ball shaped. 
     The dimensions of the curbs may be of any suitable size/dimensions to facilitate protection of the transition point between structural surfaces. In some embodiments, a curb is between 2 inches and 24 inches in height (e.g., 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, 7 inches, 8 inches, 9 inches 10 inches, 11 inches, 12 inches, 13 inches, 14 inches, 15 inches, 16 inches, 17 inches, 18 inches, 19 inches, 20 inches, 21 inches, 22 inches, 23 inches, 24 inches, or ranges therebetween (e.g., 8-16 inches).

In some embodiments, a curb is between 0.5 feet and 24 feet in length (e.g., 6 inches, 12 inches, 2 feet, 3 feet, 4 feet, 5 feet 6 feet, 7 feet, 8 feet, 9 feet 10 feet, 11 feet, 12 feet, 13 feet, 14 feet, 15 feet, 16 feet, 17 feet, 18 feet, 19 feet, 20 feet, 21 feet, 22 feet, 23 feet, 24 feet, or ranges therebetween (e.g., 2-12 feet). In some embodiments, the various segments of the curbs herein are of any suitable dimensions (e.g., lengths, widths, angles, etc.) to produce the protective curbs described herein. For example, the face angled head segment, and/or angled foot segments may be, independently, between 1 inch and 24 inches in length (e.g., 1 inch, 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, 7 inches, 8 inches, 9 inches 10 inches, 11 inches, 12 inches, 13 inches, 14 inches, 15 inches, 16 inches, 17 inches, 18 inches, 19 inches, 20 inches, 21 inches, 22 inches, 23 inches, 24 inches, or ranges therebetween). In some embodiments, the vertical engagement segments, locking segments, floor engagement segments, etc. may be, independently, between 0.25 inches and 8 inches in length (e.g., 0.25 inches, 0.5 inches, 0.75 inches, 1 inch, 2 inches, 3 inches, 4 inches, 5 inches, 6 inches, 7 inches, 8 inches, or ranges therebetween). As described herein, the transition angles between segments may be of any suitable angle to provide the proper dimensions for a particular application. 
     In some embodiments, combination of the curb, the filler material, and the seals/welds creates a barrier between the structural surface and an outside object. The outside object may be equipment, machinery, or vehicles operated by an individual such as forklifts, tractors, trucks, haulers, and the like. 
     In some embodiments, curbs are provided that are composed of a damage resistant material (e.g., impact resistant, abrasion resistant, low coefficient of friction, etc.), such as a polymer, metal, alloy, combinations thereof, etc. 
     In some embodiments, one or more elements of the curb systems described herein (e.g., curb, wall panel, etc.) comprise and/or are manufactured from a composite material, such as, a polymer matrix (e.g., vinylester, polyester, etc.), epoxy, phenol formaldehyde, polyester thermosetting plastic (e.g., PEEK, PEKK, PPS), etc., reinforced with fibers, such as carbon, aramid, glass, Kevlar, boron, basalt, Hybor, quartz, asbestos, etc. In some embodiments, the composite materials comprise additional components, such as, metal, metal foil (e.g., TiGr), or fiber metal laminate. In some embodiments, the composite materials are generally are “cured” into a stronger form through an endothermic chemical reaction, which requires the addition of energy, for example, by way of heating or irradiation. Examples of composite materials used in various embodiments of this herein include graphite fiber reinforced epoxy, fiber reinforced plastic (FRP), glass-fiber reinforced plastic (GRP), carbon-fiber reinforced plastic (CRP), metal matrix composites (MMC), and reinforced carbon-carbon (carbon fiber in a graphite matrix). 
     In some embodiments, one or more elements of the curb systems described herein (e.g., curb, wall panel, etc.) comprise and/or are manufactured from a fiber reinforced plastic (FRP). FRPs are a category of composite plastics that use elongated fibrous materials to alter and/or enhance characteristics of the plastic, such as mechanical characteristics (e.g., strength, elasticity, rigidity, etc.). FRP manufacturing typically involves two distinct processes: (1) the fibrous material is manufactured and formed, and (2) the fibrous material is bonded with the polymer matrix during molding. The fibers may be manufactured in two- or three-dimensional orientations (e.g., aligned along a plane x- and y-directions, fibers incorporated in the x-, y- and z-directions). Fiber preforms may be manufactured in sheets, continuous mats, or as continuous filaments for spray applications. The four major ways to manufacture the fiber preform is through the textile processing techniques of weaving, knitting, braiding and stitching. A rigid structure is usually used to establish the shape of FRP components. In some embodiments, parts are laid up on a flat surface referred to as a “caul plate”” or on a cylindrical structure referred to as a “mandrel.” However, most fiber-reinforced plastic parts are created with a mold or “tool.” In some embodiments, the molding process of FRP begins by placing a fiber preform on or in a mold. The fiber preform may be dry fiber, or fiber that already contains a measured amount of resin (“prepreg”). Dry fibers are “wetted” with resin either by hand or the resin is injected into a closed mold. The part is then cured, leaving the matrix and fibers in the shape created by the mold. Heat and/or pressure are sometimes used to cure the resin and improve the quality of the final part. Different methods of forming include bladder molding, compression molding, autoclave and vacuum bag, mandrel wrapping, chopper gun, filament winding, pultrusion, and resin transfer molding. In some embodiments, any suitable materials sand methods for the production of one or more elements of the curb systems described herein (e.g., curb, wall panel, etc.) out of FRP materials find use in embodiments herein. 
     In some embodiments, one or more elements of the curb systems described herein (e.g., curb, wall panel, etc.) comprise and/or are manufactured from a polymer material. Some non-limiting examples of suitable nondegradable materials include polymeric materials, for example, polyolefins such as polyethylene (e.g., ultra-high molecular weight polyethylene (UHMWPE or UHMW)) and polypropylene including atactic, isotactic, syndiotactic, and blends thereof; polyethylene glycols; polyethylene glycol (PEG) coated polyethylene terephthalate (PET), polyethylene oxides; polyisobutylene and ethylene-alpha olefin copolymers; fluorinated polyolefins such as fluoroethylenes, fluoropropylenes, fluoroPEGSs, and polytetrafluoroethylene; polyamides such as nylon, Nylon 6, Nylon 6,6, Nylon 6,10, Nylon 11, Nylon 12, and polycaprolactam; polyimines; polyesters such as polyethylene terephthalate, polyethylene naphthalate, polytrimethylene terephthalate, and polybutylene terephthalate; polyethers; polybutester; polytetramethylene ether glycol; 1,4-butanediol; polyurethanes; acrylic polymers; methacrylics; vinyl halide polymers such as polyvinyl chloride; polyvinyl alcohols; polyvinyl ethers such as polyvinyl methyl ether; polyvinylidene halides such as polyvinylidene fluoride and polyvinylidene chloride; polychlorofluoroethylene; polyacrylonitrile; polyaryletherketones; polyvinyl ketones; polyvinyl aromatics such as polystyrene; polyvinyl esters such as polyvinyl acetate; etheylene-methyl methacrylate copolymers; acrylonitrile-styrene copolymers; ABS resins; ethylene-vinyl acetate copolymers; alkyd resins; polycarbonates; polyoxymethylenes; polyphosphazine; epoxy resins; aramids; rayon; rayon-triacetate; spandex; silicones; and copolymers and combinations thereof. 
     In some embodiments, one or more elements of the curb systems described herein (e.g., curb, wall panel, etc.) comprise and/or are manufactured from ultra-high-molecular-weight polyethylene (UHMW), or high-modulus polyethylene as is it also known, which is a subset of thermoplastic polyethylene. UHMW is well-known in the art of plastics by having high impact strength and abrasion resistance (Stein, H. L.,  Ultra High Molecular Weight Polyethylene , Engineered Material Handbook, Vol. 2, 167-171 (1998); herein incorporated by reference in its entirety). UHMW is 15 times more resistant to abrasion than carbon steel and its coefficient of friction is significantly lower than that of nylon and acetyl. UHMW has superior abrasion resistance than Teflon. The combination of high impact strength, coefficient of friction, and abrasion resistance of UHMW makes well-suited for applications where lower molecular weight grades fail. UHMW has been used in medical devices, cables, wire, and fibers for personal armor, cut-resistant gloves, bow strings, fishing line, climbing gear, and industrial webbing. UHMW is both FDA and USDA approved for use in food processing and medical applications. UHMW cannot be transformed and molded by conventional plastic processing techniques such as injection molding, blow molding or thermoforming. Rod tubing and profiles of UHMW are typically created by compression molding or ram extrusion processing. During ram extrusion, UHMW powder is gravity fed into a chamber and a hydraulic ram pushes the powder from this chamber into a die. The die is the shape of the desired plastic, a certain diameter rod, a certain tube, or a profile shape. Heaters are employed on the outside of the die to heat the plastic and make it form into the shape of the die. The hydraulic ram moves back and forth continuously feeding the powder into the die. As the material comes out of the die, it travels the length of the conveyor after which it is cut to length. Ram extrusion does not shear the material that is being manufactured as does single screw extrusion which employs a rotating screw to move the material. It moves the material by hydraulically pushing it through the die which is the desired shape of the end product. 
     In some embodiments, curbs herein are shaped/formed by any suitable technique, such as ram extrusion, compression molding, gel spinning, sintering, 3D printing, etc. The curb may be formed into a profile configured for particular structural surfaces (e.g., vertical/horizontal, off-vertical/horizontal, vertical/off-horizontal, off-vertical/off-horizontal, corner, ramp, doorway, un-even surface, etc.). In some embodiments, any embodiments described herein for the junctions of orthogonal structures (e.g., vertical wall meeting a horizontal floor) will also find use in non-orthogonal junctions. 
     In some embodiments, curb systems herein comprise the filler material. In some embodiments, filler is any suitable material to fill the void between the curb and the structural surfaces, such as, for example, concrete, a concrete-filler mixture, a cement-filler mixture, a concrete-polymer mixture, industrial foams, polymers, insulation, plastics, and the like. In some embodiments, the filler material fills the cavity behind the curb, prevents damage to the curb, seals the area behind the curb, prevents infestation, prevents bacterial/mold growth, prevents water invasion, and/or structurally reinforces the structural surfaces and/or curb. Similarly, the interior and/or surface of walls, panels, doors, floors, etc. may comprise similar materials to the fillers above. 
     In some embodiments, the curb systems herein interact with floor/flooring materials (e.g., are adhered to). Suitable floor/flooring materials include, but are not limited to: ceramic (e.g., tile), wood, concrete, cement, glass, natural or synthetic stone, urethane, sheet vinyl, vinyl composite, rubber, laminate, linoleum, polyaspartics, epoxies, etc. In some embodiments, curb systems are tailored (e.g., appropriate adhesives/sealants/chemical welds are selected) to the floor/flooring material present. 
     In some embodiments, adhesives, glues, and/or sealants are provided in the systems herein to adhere two or more components together (e.g., curb to floor, curb to wall, filler to wall, filler to floor, etc.). In some embodiments, adhesives, glues, and/or sealants are provided in the systems herein to seal a gap between to components. Exemplary adhesives, glues, and/or sealants that find use in some embodiments herein include, but are not limited to: epoxies, silicone-based, cyanoacrylates, urethanes adhesives, acrylic adhesives, rubber cements, pressure sensitive adhesives, heat sensitive adhesives, thermosetting structural adhesives, UV-curing adhesives, acrylic, foam, latex sealants, polysulfide sealants, polyurethane sealants, etc. In some embodiments, the type of adhesives, glues, and/or sealants is selected based on the materials to be adhered/sealed and/or the desired characteristics of the adhesion/seal (e.g., strength, durability, lifetime, waterproof, bacteria/mold resistance, etc.). 
     In some embodiments, a chemical weld is provided in the systems herein to adhere two or more components together (e.g., curb to floor, curb to wall, filler to wall, filler to floor, etc. and/or to seal a gap between to components. Compared to glues and sealants, a chemical weld is a more permanent method for bonding two materials. Chemical welding involves the application of one or more materials (e.g., solvents, reactants, components, etc.) on a surface or between two surfaces; a chemical reaction within the applied materials and/or between the applied materials and the surfaces results in chemical bonding of the surfaces (e.g., to each other, to the weld materials, etc.).
