Soil disturbed at construction sites may runoff into natural water bodies, such as streams, lakes, and estuaries, or onto roads. The environmental impacts of sediment-laden water entering wetlands, streams, or waters of the United States may be significant: failed re-vegetation efforts post-construction, degradation of aquatic habitats natural to the construction sites, or sediment clogs of storm sewers. Reducing the environmental impacts of the disturbed soil may necessarily require control of this sediment-laden runoff. Accordingly, a construction plan may comprise approaches to maintain soil original to a construction site at the construction site.
Silt fence may function to keep soil local to a construction site during construction activities. Silt fence installed at a construction site may generally comprise at least one silt fence section, which may comprise end posts and porous fabric stretched between the end posts. As sediment-laden runoff flows from the construction site to appropriately placed silt fence, the porous fabric may limit the transport of eroded or disturbed soil from the construction site. Specifically, the silt fence may slow the flow of sediment-laden runoff water and separate the runoff components. The sediment may drop out and settle at the silt fence and water may flow through the silt fence. The silt fence may form a pond boundary as the dropped sediment forms a sediment pond of local soil. Accordingly, silt fence may separate construction site runoff into water and sediment, and may help form a boundary for a sediment pond at the construction site.
As described herein above, silt fence installed at a construction site may comprise porous fabric. Characteristics of the porous fabric, such as permeability, or permittivity, may support separating construction site runoff into sediment and water. However, holes, rips, ultra violet degradation, or other damage to the porous fabric may impact silt fence integrity. If the installed silt fence is unable to separate runoff components, at the very least, adjacent storm drains may clog. If the installed silt fence is unable to create a sediment pond, at the very least, receiving waters may suffer. Accordingly, construction plans may comprise approaches to maintain silt fence integrity.

It is to be understood that other embodiments may be utilized because structural and process changes may be made without departing from the scope of the present invention.
Silt fence may function to keep soil local to a construction site during construction activities. The silt fence may comprise porous fabric, which is subject to damage. For example, damage to the silt fence may occur during transport of the silt fence to the construction site. Alternatively, damage to the silt fence may occur during construction activities at the construction site. In an embodiment of the present invention, damage may comprise holes or rips. However, the types or categories of damage are provided for exemplary purposes, only, and are not meant to be limiting. Accordingly, construction site plans may contemplate damage to silt fence.
A section of silt fence (100) may comprise a first end post (110), a fabric (120), and a second end post (130). In an exemplary embodiment, the fabric (120) may comprise a front side (140) and a back side (not shown). In an exemplary embodiment, the fabric may comprise a fabric weave (150) having a fabric weave direction (152), as indicated by the arrows. As shown herein, for example, the fabric weave direction may be substantially vertical, substantially horizontal, some combination thereof. The fabric weave direction is shown for exemplary purposes, only, and is not meant to be limiting. Accordingly, silt fence may comprise structural supports and fabric.
In an embodiment, for example, the first end post (110) and the second end post (130) may be positioned and used to hold and stretch the fabric (120). For example, in an embodiment, the stretch of the fabric (120) may encourage permeability or support formation of a sediment pond (170). The positioning of the first end post (110), the second end post (130), and the fabric (120), are shown for exemplary purposes. In accordance with the present invention described herein, construction of a section of silt fence (100) and positioning of a first end post (110) and a second end post (130) relative to a fabric (120) may support silt fence functionality. Accordingly, construction of a section of silt fence may reflect construction site plans.
As described herein above, a section of silt fence (100) may comprise a first end post (110), a second end post (130), and a fabric (120). In use, the fabric (120) component of a section of silt fence (100) may function to trap soil particles from sediment-laden runoff and may support settlement of the soil particles into a sediment pond. In an exemplary embodiment, the fabric (120) may comprise a geotextile fabric, and choice of geotextile fabric may support silt fence functionality. For example, in an embodiment, geotextile fabric may be chosen based on permeability or permittivity characteristics. In another exemplary embodiment, geotextile fabric may be chosen based on water resistance or resistance to ultra violet degradation characteristics. Indeed, environmental conditions, transport conditions, and construction activities, for example, may influence a choice of geotextile fabric for use in silt fence. The geotextile fabric characteristics described herein are not meant to be limiting, and are shown for exemplary purposes, only. Accordingly, silt fence may comprise geotextile fabric, and the geotextile fabric may comprise characteristics supporting construction plans.
In an exemplary embodiment, as shown in
As will be described herein below, a silt fence patch of the present invention may adhere to fabric (120) to cover and repair damage (160) to a section of silt fence (100). Specifically, in an embodiment of the present invention, as described herein below, a silt fence patch may communicate with an adhesive, and the adhesive may communicate with the fabric (120) of a section of silt fence (100). To that end, the fabric (120) may comprise an amount of surface area to support communication with the adhesive. In an exemplary embodiment, the surface area may comprise an adhering area (167). In an embodiment, damage (160) to the section of silt fence (100) may comprise the adhering area (167) surrounded by a damage border or damage boundary (168). In other words, in an exemplary embodiment of the present invention, the damage (160) may comprise a damage boundary (168), and the damage boundary (168) may surround the first group of fibers (162), the second group of fibers (164), the separation space (166), and the adhering area (167). Accordingly, damage to silt fence fabric may comprise an area of fabric supporting adhesive functions.
Silt fence may be manufactured as a roll and installed in 6-foot sections. Each 6-foot section of silt fence may be installed between two supporting posts. In an embodiment, the supporting posts may be provided during silt fence installation. In another embodiment, for example, a roll may include wooden posts already stapled to the silt fence at 6-foot intervals. To that end, the posts may identify each separate 6-foot section. Further, the stapled posts may support silt fence installation. Accordingly, silt fence manufacture may support silt fence installation.
Regulations may require that compromised silt fence be replaced with a new 6-foot section of silt fence. This replacement process may require unplanned time and resources. In other words, processes for repairing damaged silt fence may impact labor and supply costs and construction schedules. Rather than repairing damage to silt fence with replacement sections of silt fence, an embodiment of the present disclosure provides for a silt fence patch. For example, in an embodiment of the invention described herein, a silt fence patch may be applied in situ to silt fence in use at a construction site. Accordingly, a silt fence patch may reduce construction plan impacts associated with replacement sections.
As described with respect to
In an exemplary embodiment, the silt fence patch (200) may further comprise an adhesive layer (220) in communication with the geotextile fabric (210). In an exemplary embodiment, the adhesive layer (220) may promote adhesion between the geotextile fabric (210) and silt fence fabric (not shown) of a section of silt fence, as described in
In an embodiment of the present invention, the adhesive layer (220) may form an adhesive bead. The location, size, and shape of the bead shown is for exemplary purposes, only, and is not meant to be limiting. Indeed, many qualities, such as adhesion and curing qualities, may impact the bead. For example, a bead position, size, and shape may maximize adhesion between a silt fence patch (200) and a damage boundary of a section of silt fence. Alternatively, a bead position, size, and shape may maximize runoff flow through a section of silt fence. In an exemplary embodiment, a bead position, size, and shape may balance these potentially conflicting considerations. For example, in an embodiment, the adhesive layer (220) may be positioned substantially close to the edge (214) of the geotextile fabric (210). In an additional exemplary embodiment, the adhesive layer (220) may be limited to surface area near the edge (214) of the geotextile fabric (210), and may not communicate with a center (222) of the geotextile fabric (210). Accordingly, a silt fence patch may comprise an adhesive layer, which may support silt fence functionality.
In an exemplary embodiment, the silt fence patch (200) may further comprise a backing (230) in communication with the adhesive layer (220). In an exemplary embodiment, the backing (230) may comprise a first side (232) in communication with the adhesive layer (220), and a second side (not shown). The backing (230) may protect the adhesive layer (220) prior to use of the silt fence patch (200) to repair damage to a section of silt fence. In another embodiment, for example, the first side (232) of the backing (230) may communicate with the back side (not shown) of the geotextile fabric (210). With this in mind, in an exemplary embodiment, the protective functions of the backing (230) may extend to protecting the back side (not shown) of the geotextile fabric (210). Accordingly, a backing may protect either or both an adhesive layer and geotextile fabric prior to use in repairing damage to a silt fence.
In an exemplary embodiment, indicia may be printed on the second side (not shown) of the backing (230). Indicia may comprise, for example, instructions for use of the silt fence patch (200), weave direction of the silt fence patch (200), or a supplier's logos. The types of indicia are provided for exemplary purposes, only, and are not meant to be limiting. Accordingly, a silt fence patch may comprise a backing, and the backing may communicate indicia.
As described herein above, indicia, such as instructions, patch weave direction, or logos may be printed on a backing (230) of a silt fence patch (200). In an alternative embodiment, the indicia may be printed directly on the geotextile fabric (210) of the silt fence patch (200).
In an exemplary embodiment, silt fence patch orientation may impact silt fence functionality. For example, as described herein above, both a section of silt fence fabric and silt fence patch fabric may comprise geotextile fabrics. The geotextile fabrics may comprise a network of woven fibers. With respect to a section of silt fence fabric, pockets of air may form between the woven fibers, and the pockets may support flow of runoff through the section of silt fence. The larger the pockets, the greater the amount of fluid flow through the section of silt fence. At the same time, the larger the pockets, the less likely the silt fence may trap sediment on a front side of the section of silt fence to form a sediment pond. Accordingly, silt fence fabric weave may impact silt fence functionality.
Further, misalignment of patch weave direction to fabric weave direction may reduce pocket size and may impact silt fence functionality. In an exemplary embodiment, as shown in
In another exemplary embodiment, as shown in
A silt fence patch, as described in
In an exemplary embodiment, repairing a silt fence (400) may further comprise smoothing the applied patch (470). Smoothing the applied patch (470) may promote the adhesive layer forming a seal between the adhering area and the silt fence patch. Accordingly, repairing a silt fence may comprise applying and smoothing a silt fence patch to a damage boundary of a section of silt fence.
As shown in an embodiment of
As described herein above, geotextile fabrics comprise fibers, and the fibers create pockets through which fluid may flow. Misalignment of patch weave direction relative to fabric weave direction may reduce available pocket size between fibers on a section of silt fence. That is, with reference to
In a further embodiment of the present invention, the section of repaired silt fence (600) may border a sediment pond (670). In a further exemplary embodiment, the sediment pond (670) may communicate with the section of repaired silt fence (600) at an interface (680). Accordingly, a silt fence patch may repair a section of silt fence, while allowing for runoff flow through the section of silt fence and sediment pond formation at the section of silt fence.
As described in
An exemplary embodiment of the present invention may comprise a sheet of silt fence patches, each silt fence in accordance with the present disclosure.
In an exemplary embodiment, the backing (730) may comprise a second side (734). In an embodiment, for example, indicia may be printed, embossed, or scored on the second side (734) of the backing (730). The methods for communicating indicia onto the second side (734) of the backing (730) are provided for exemplary purposes, only, and are not meant to be limiting. Indicia may comprise, for example, an outline of a first silt fence patch (740). In an exemplary embodiment, indicia may further comprise, at least, an outline of a first silt fence patch (740) and an outline of a second silt fence patch (742). In a further exemplary embodiment, indicia may comprise, at least, an outline of a first silt fence patch (740), an outline of a second silt fence patch (742), and an outline of a third silt fence patch (744). In an exemplary embodiment, the outlines may comprise score lines. Descriptions of indicia are provided for exemplary purposes, only, and are not meant to be limiting. Further, the number and arrangement of indicia of outlines of silt fence patches on the backing (730) are provided for exemplary purposes, only, and are not meant to be limiting. Accordingly, a silt fence patch sheet may comprise a geotextile fabric, an adhesive layer and a backing, and the backing may communicate silt fence patch dimensions.
In an exemplary embodiment, the silt fence patch sheet (700) may comprise continuous and parallel forms of the geotextile fabric (710) and the backing (730). As described above, the adhesive layer (720) may communicate with both the geotextile fabric (710) and the backing (730). However, in an embodiment, the adhesive layer (720) may not form continuously between the geotextile fabric (710) and the backing (730). Similar to the silt fence patch described in
In another exemplary embodiment, the adhesive layer (720) may comprise an adhesive bead position, size, and shape that supports adhesion of the backing (730) to the geotextile fabric (710). In an embodiment, the adhesive layer (720) may, for example, support communication between the geotextile fabric (710) and the backing (730) during transport or storage of the silt fence patch sheet (700). With this in mind, in an exemplary embodiment, the backing (730) may protect the geotextile fabric (710) from damage due to, for example, external elements, such as construction debris, prior to use of the silt fence patch sheet (700). Accordingly, a silt fence patch sheet may comprise an adhesive layer, which may facilitate storing and transporting the silt fence patch sheet.
In another exemplary embodiment, the indicia may comprise user instructions for removing a silt fence patch from the silt fence patch sheet (700). In a further exemplary embodiment, the indicia may comprise instructions for repairing a section of silt fence with a silt fence patch, in accordance with the present disclosure. In another exemplary embodiment, indicia may comprise business identifiers, such as logos. The indicia may also comprise patch weave direction. The indicia discussed herein are provided for exemplary purposes, and are not meant to be limiting. Accordingly, a silt fence patch sheet comprising a geotextile fabric, an adhesive layer, and a backing may communicate user instructions.
In an exemplary embodiment, a silt fence patch sheet (700) may comprise a wide sheet, a long sheet, or some combination thereof. Ease of transportation and storage may influence dimensions of the silt fence patch sheet (700). In an exemplary embodiment of the present invention, as shown, the silt fence patch sheet (700) may form a roll (750). In this way, a construction site manager, for example, may manage a roll (750) comprising a silt fence patch sheet (700). In doing so, the construction site manager may manage a plurality of individual silt fence patches. In an embodiment, for example, the roll (750) may comprise a silt fence patch sheet (700) comprising approximately 100 feet in length and approximately one foot in width. The roll (750) may comprise a silt fence patch sheet (700), which may comprise at least one silt fence patch. The dimensions of the roll (750) and the number of silt fence patches provided therewith are provided for exemplary purposes, only, and are not meant to be limiting. In alternative embodiments, for example, the silt fence patch sheet (700) may fold into multiple smaller sheets, or may comprise a single, small, flat sheet. Accordingly, a form of silt fence patch sheet may facilitate transportation and storage of multiple silt fence patches.
As described herein above with respect to
As described above, in an exemplary embodiment of a present disclosure, a silt fence patch comprising geotextile fabric, an adhesive layer, and a backing may be used to repair damage to a section of silt fence. Also, as described above, a silt fence patch sheet may comprise a plurality of silt fence patches. When, for example, a rip or hole is identified in a section of silt fence in the field during normal construction inspections, an inspector may brush off any evident soil from the damaged area of the section of silt fence. The inspector may determine the proper patch size to use to cover the damaged area and cut a silt fence patch from a silt fence patch roll. To apply the silt fence patch to the damaged area, the inspector may remove the backing, which may comprise plastic or paper, from communication with the adhesive layer. The inspector may then apply the silt fence patch to the damaged area, and rub the silt fence patch with the removed backing to ensure a good seal. For optimal runoff flow, instructions on the backing of the silt fence patch roll may include an UP arrow, which may indicate patch weave direction. The inspector may reference this indicia to align the patch weave direction with the silt fence fabric weave direction. Accordingly, a silt fence patch, in accordance with the present invention, and selected from a roll of silt fence patches, may repair damage to a section of silt fence in situ.
In an exemplary embodiment of the present invention, a method of repairing a silt fence (800) may further comprise removing a backing from the selected patch (860) and aligning a patch weave direction of the selected patch with a fabric weave direction of the silt fence (870). As described herein above with respect to
In a further exemplary embodiment, repairing a silt fence (800) may comprise applying the selected patch to the damage boundary (880) and smoothing the applied patch (890). Accordingly, a silt fence patch for repairing a section of silt fence may be selected from a sheet of silt fence patches, and the selected patch may be applied to cover damage to the section of silt fence.
