Ranges may be expressed herein as from “about” or “approximately” one particular value and/or to “about” or “approximately” another particular value. When such a range is expressed, another embodiment includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another embodiment.
- With reference now to the drawing figure, wherein like reference numbers represent corresponding parts throughout the several views a perspective view of a section of
sheet piling 10 with aversive additive is shown according to an example embodiment of the present invention. The sheet piling comprises anelongate member 20 having first andsecond sides second ends first side 30 includes amale coupling element 50, and thesecond side 32 includes afemale coupling element 52. - A plurality of two or more sheet piling
members 10 may optionally be assembled into a sheet piling array or structure, whereby the male andfemale coupling elements members 10 are installed below grade, for example by sequentially driving sheet piling members into the ground, with thesecond ends 42 thereof positioned at a specified depth below grade. - In the depicted embodiment, the
sheet piling member 10 comprises a corrugated profile, having amedial panel 60 between first and secondtransverse panels first side flange 66 between the firsttransverse panel 62 and thefirst side 30, and asecond side flange 68 between the secondtransverse panel 64 and thesecond side 32. The first andsecond side flanges medial panel 60, whereby a sheet piling member thickness is defined between the parallel planes. Thesheet piling member 10 is preferably an integrally formed unitary member of substantially rigid material such as, for example, PVC, HDPE, steel, fiberglass or other polymeric or metal materials of construction. - In alternate embodiments, the
sheet piling 10 can comprise an elongate member having other corrugated (for example C-shaped, S-shaped, U-shaped, W-shaped cross-sectional profiles), a flat profile, or otherwise configured shapes. The sheet piling may or may not include interengaging male and female connector elements at opposed sides thereof, and the connectors may optionally comprise profiles other than as depicted. - The sheet piling of the present invention incorporates an aversive agent into or onto the plastic or other material of construction used to form the sheet piling members. In example forms, the aversive agent is a chemical, botanical or other material that repels burrowing rodents or other animals. Optionally, the aversive agent does not harm the animal, but is very bitter and spicy, so the taste and smell senses are profoundly influenced in a negative way, causing the rodents stop gnawing and learn to stay away. The aversive agent can be blended into the base construction material of the sheet piling, can be co-molded or co-extruded as an outer cladding or coating over the base construction material, and/or can be applied as by painting or other surface treatment methods, then allowed to dry and harden.
- In further embodiments, the material of the sheet piling optionally incorporates fibers, for example chopped glass strands, nylon fibers and/or other fibrous, pointed, abrasive or otherwise tactile aversive materials, to add a tactile element that is disfavored by burrowing rodents or other animals, for example causing skin or eye irritation, itching, or other sensory disincentive. Optionally, the fibers are applied to or concentrated in, the exterior portions of the material forming the sheet piling, and/or may be selectively oriented to enhance tactile action against animals coming in contact therewith. Sand, glass beads, crushed glass particles, or other materials may be incorporated in or on the material of the sheet piling, for example embedded within the sheet piling or applied onto the sheet piling as a coating. Additionally or alternatively, a metal or glass fiber mesh, belting, cording and/or strands may be incorporated into or onto the sheet piling. In further embodiments, the material of the sheet piling optionally also incorporates one or more colorant(s), phosphorescent agent(s), and/or reflective agent(s) that is/are disfavored by or repellant to burrowing rodents or other animals. Also, a distinct color, such as for example a bright green colorant, may be used to distinguish an aversive-containing sheet piling from a standard sheet piling not incorporating an aversive.
- The aversive agent(s) may be introduced into the material of construction in various manners, such as for example by automated mixing of pelletized materials into the additive feeder or other material feed stream of a plastics blender system, and feeding into a melt extruder. The aversive agent(s) may optionally be incorporated into a carrier, binder, filler or other material(s), such as for example ethylene vinyl acetate (EVA). Example addition rates of aversive agents that may be adapted for use with the invention include Rodrepel™ by C Tech Corporation at an addition rate of about 2.5% to 5% (denatonium benzoate (bitter)); and/or RepelaTM by Aversion Technologies, Inc. at an addition rate of about 2%-3% (denatonium benzoate (bitter) and capsaicin (spicy/odor)). In alternate embodiments, the aversive content comprises about 0.5% to about 10%, or about 1% to about 7.5% of the material composition forming the sheet piling. Optionally, the aversive may be concentrated at external portions of the sheet piling.
- While the invention has been described with reference to preferred and example embodiments, it will be understood by those skilled in the art that a variety of modifications, additions and deletions are within the scope of the invention, as defined by the following claims.
