Definitions

  • the present invention relates to sheets for providing a barrier against the penetration of insects and methods of protecting a building against the penetration of insects into the building.
  • Buildings may be subject to entry by insects. Some insects, such as termites will damage the building. In general, termites enter the building where it contacts the ground. From there, the termites may spread rapidly throughout the building, causing significant damage to any timber.
  • plastic sheets have been employed to guard against the entry of insects, particularly termites to buildings.
  • these barriers are in the form of plastic sheets and are placed either under a concrete slab or the entire building including the footings (ie. in full soil contact), whereby the plastic sheet also acts as a moisture barrier.
  • the main problem with using plastic sheeting is that some termites are capable of eating through the plastic, thereby causing a breakdown of the physical barrier to their entry into the building.
  • the plastic sheet incorporates an insecticide either throughout the sheet or in localised areas of the plastic sheet, whereby the insecticide is controllably released or leached from the plastic into the surrounding soil.
  • a “buffer zone” around the plastic sheet is thus created, in which insects will be killed should they enter this zone.
  • insecticide leaching plastic sheet Another problem with the insecticide leaching plastic sheet is that the release of such chemicals into the general environment may harm the environment and kill other organisms. Furthermore, the insecticide may be washed from the soil during heavy rain fall, which may result in pollution to run-off as well as the loss of the lethal “buffer zone”. Furthermore, the insecticide leaching plastic sheet has only limited applications because, in order to work, it requires a substrate into which the termiticide can leach.
  • a liquid insecticide typically deltamethrin is contained between two sheets of impermeable plastic.
  • the liquid insecticide is released into a localised area around the penetration point where it kills any termites which are present.
  • problems with this arrangement one of these being that once the plastic has been breached and the insecticide released, that there is no further termiticide barrier.
  • release of concentrated insecticide ie. in liquid form
  • Concentrated insecticides also pose a substantial health risk to humans.
  • this type of barrier could not be used in a location where it would be likely that humans would come in contact with the liquid insecticide, such as at or above ground level.
  • Another problem is that the plastic/liquid insecticide sheeting is difficult and dangerous to handle because it is bulky and also because when it is cut to shape for use, the person handling the sheeting is often exposed to the liquid insecticide.
  • a sheet for providing a barrier against the penetration of insects comprising at least one insecticide distributed through a plastics material wherein the insecticide is substantially retained in the plastics material.
  • the insecticide Because the insecticide is retained, the insecticide does not substantially leach from the plastics material. Thus, its activity is expressed throughout the plastics material.
  • the plastics material provides a physical barrier against the penetration of insects and the insecticide provides a chemical barrier against the penetration of insects.
  • the surfaces of the sheet are substantially identical, whereby, in use, the sheet may be laid with either surface facing up.
  • the sheet is approximately 0.1-1 mm thick.
  • the sheet is approximately 0.2-0.5 mm thick.
  • the sheet is approximately 0.2 or 0.5 mm thick.
  • the plastics material is any synthetic or semi-synthetic compound formed by organic condensational polymerisation.
  • the plastics material is any plastics material which can be moulded or extruded into objects or films or fibres.
  • the plastics material is any one or a combination of polyamide (nylon), polyethylene, ethylene vinyl acetate, polystyrene, polyvinylchloride, synthetic rubber (eg. neoprene), polymethylmethacrylate (acrylic), polypropylene and polyurethane.
  • the plastics material is low density polyethylene.
  • the plastics material contains a UV stabiliser.
  • the plastics material contains a white colouring agent.
  • the sheet is substantially impact resistant according to Australian standard AS 4347.6.
  • the sheet is substantially impermeable to water.
  • vapour permeance through the sheet is less than 0.02 mg/Ns.
  • the at least one insecticide is any compound that exhibits sufficient lethal control and/or repellent effects against insects.
  • a separate repellent compound in addition to the insecticide is distributed through the plastics material.
  • the repellent compound does not significantly leach from the plastics material.
  • the repellent compound provides a repellent barrier against the penetration of insects in addition to the chemical and physical barrier.
  • the at least one insecticide is any one or combination of pyrethrum, synthetic pyrethroids, organo-chlorines, organo-sulfurs, carbamates, organo-phosphates, formamidines, nicotinoids, spinosyns, phenylpyrazoles, pyrroles, pyrazoles, dinitrophenols, pyridazinones, quinazolines, and benzoylureas.
  • the insects impeded by the sheet will be termites.
  • the at least one insecticide is a termiticide.
  • the termiticide is a synthetic pyrethroid.
  • the termiticide is any one or combination of bifenthrin, permethrin, deltamethrin, lambda-cyhalothrin, cypermethrin, alpha-cypermethrin, tetramethrin, and cyfluthrin or any other synthetic pyrethroid.
  • the concentration of insecticide in the plastic is less than 5 weight %.
  • the concentration of insecticide in the plastic is greater than 0.01 weight %.
  • the insecticide is bifenthrin.
  • the insecticide is bifenthrin
  • its concentration in the plastic is preferably 0.05 to 1.0 weight %.
  • the bifenthrin has a concentration of approximately 0.05-0.1 weight %, more preferably, approximately 0.1 weight %.
  • Bifenthrin provides a repellent barrier as well as a chemical barrier to the penetration of termites.
  • the sheet is formed in a blown film extrusion process.
  • the sheet is formed in an extrusion process.
  • the sheet is formed in the extrusion process if it has a thickness of approximately 0.5 mm. If the sheet has a thickness of approximately 0.2 mm, then preferably it is formed in the blown film extrusion process.
  • the sheet is formed from a master batch of plastic containing insecticides.
  • the master batch has a concentration of insecticide which is stably supported in the plastic.
  • At least one surface of the sheet is embossed.
  • at least one surface of the sheet is smooth.
  • a method of protecting a building against the penetration of insects into the building comprising the step of positioning one or more sheets of a plastics material above the footings of the building, wherein the plastics material contains at least one insecticide distributed therethrough.
  • the step of positioning the sheets of plastics material further involves positioning the sheets around the perimeter of the building at least extending between an outer wall of the building and an inner frame of the building.
  • the sheets of plastics material restrict penetration by insects to the perimeter cavity between the outer wall and inner frame.
  • the step of positioning the sheets of plastics material further involves positioning the sheets under all or part of a concrete slab of the building.
  • the insecticide is substantially retained in the plastics material.
  • the sheet acts as a moisture barrier for at least a portion of the building.
  • the sheet acts as the damp proof course of the building.
  • the sheets of plastics material comprise sheets according to the first aspect of the present invention.
  • FIG. 1 is a schematic view and a magnified view of a sheet according to preferred embodiments of the present invention in a cavity barrier application;
  • FIG. 2 is a schematic view of the sheet of FIG. 1 in an alternative cavity barrier application including a separate damp proof course sheet;
  • FIG. 3 is a schematic view of the sheet of FIG. 1 in a complete underslab application.
  • the sheet 10 comprises a plastics material having an insecticide dispersed therethrough and retained in the plastics material.
  • the sheet 10 provides a physical and chemical barrier to impede the penetration of insects by virtue of the fact that it is manufactured from a plastics material having an insecticide dispersed therethrough.
  • the sheet 10 may also provide a repellent barrier, ie. will repel insects away from its location if the plastics material also has a repellent dispersed therethrough.
  • the sheet 10 has a vapour permeance of less than 0.02 mg/Ns and therefore according to the Australian Standards is substantially impermeable to water and can be used to form a moisture barrier for a building, for example.
  • the surfaces of the sheet 10 are substantially identical such that, when the sheet 10 is used, it may be laid with either surface facing up.
  • the sheet 10 is approximately 0.1-1 mm thick, preferably 0.2 or 0.5 mm thick when purposes of sheets 10 of these different thicknesses will be described further on in the specification.
  • the plastics material may comprise any synthetic or semi-synthetic compound formed by organic condensational polymerisation and which can be moulded or extruded into objects or films or fibres.
  • Such compounds may include, but are not limited to, polyamide (nylon), polyethylene, ethylene vinyl acetate, polystyrene, polyvinylchloride, synthetic rubber (eg. neoprene), polymethylmethacrylate (acrylic), polypropylene and polyurethane.
  • the plastics material may be formed from a combination of two or more of these compounds.
  • the preferred compound used for the plastics material is low density polyethylene.
  • the plastics material may contain a UV stabiliser to prevent break down of the plastics material when exposed to sunlight. This is important in maintaining the longevity of the sheet 10 which may be in use for up to 50 or more years.
  • the plastics material may also comprise a white colouring agent so that the sheet 10 is white in colour. The white sheet 10 does not heat up as much as conventionally black plastic sheeting in the sun and is therefore cooler and easier to handle during installation.
  • the sheet 10 is substantially impact resistant, which guards against rips or tears being formed in the sheet 10 during or after installation.
  • the impact resistance of the sheet 10 is determined using the falling dart impact test outlined in Australian Standard AS 4347.6. This test involves firstly, dropping a load of 310 grams from a drop height of 660 mm, on the fold of the sheet 10 . And secondly, dropping a load of 340 grams and a drop height of 660 mm, the load is dropped twice per metre width of sheet 10 across the full width of the sheet 10 with the sheet passing if 75% of these tests do not fail.
  • the insecticides which are retained in the plastics material may be any compound that exhibits control or repellent affects against insect species, particularly termites.
  • These compounds include, but are not limited to, pyrethrum, synthetic pyrethroids, organo-chlorines, organo-sulfurs, carbamates, organo-phosphates, formamidines, nicotinoids, spinosyns, phenylpyrazoles, pyrroles, pyrazoles, dinitrophenols, pyridazinones, quinazolines, and benzoylureas.
  • a noted termiticide such as bifenthrin, permethrin, deltamethrin, lambda-cyhalothrin, cypermethrin, alpha-cypermethrin, zeta-cypermethrin, tetramethrin, and cyfluthrin.
  • Some of the aforementioned insecticide compounds may also provide a repellent effect, thereby creating the repellent barrier referred to above.
  • the insecticide is bifenthrin.
  • Bifenthrin has a non-alpha-cyano molecular structure which renders it a dermal non-sensitiser, ie. does not react substantially with a person's skin. Thus, a person handling the sheet 10 is unlikely to experience any reaction on their skin as a result of the bifenthrin in the plastics material.
  • the concentration of insecticide in the plastic is less than 5 weight % and greater than 0.01 weight %.
  • the concentration of insecticide is dependent upon the actual compound used. If the insecticide is bifenthrin, as in the preferred embodiment discussed above, then the concentration of the insecticide (bifenthrin) in the plastics material is 0.05 to 1.0 weight %, preferably 0.05 to 0.1 weight % and more preferably approximately 0.1 weight %.
  • bifenthrin provides a repellent barrier as well as a chemical barrier to the penetration of insects.
  • Manufacture of the sheet 10 involves mixing the insecticide with polymer resin to form a “mater batch”.
  • the master batch has a higher concentration of insecticide than the end sheet 10 product.
  • the concentration of insecticide in the master batch may be as high as is stably supported in the polymer matric (ie. does not react and/or leach from the plastic).
  • the insecticide is bifenthrin
  • mixing the insecticide with polymer resin to form the master batch in one embodiment involdes melting solid bifenthrin (>99% purity), melting the polymer resin separately (preferably low density polyethylene) and mixing the polymer resin and bifenthrin melts.
  • powdered bifenthrin (mixed with talcum powder) or a solution of bifenthrin may be mixed with molten polymer resin to form the master batch.
  • the concentration of bifenthrin in the master batch is approximately 2 weight %. However, the concentration of bifenthrin in the master batch may be substantially higher.
  • the master batch is solidified and formed into pellets, awaiting later dilution to achieve the desired concentration of insecticide for the end sheet 10 product. Dilution of the master batch occurs by mixing the solid master batch pellets with solid polymer pellets to form a homogenous solid mixture. The homogenous solid mixture is melted and then formed into the sheet 10 by any suitable means.
  • the sheet 10 is formed by blown film (or tubular film) extrusion of the molten monogenous mixture of plastic and insecticide.
  • Blown film extrusion involdes extruding the molten plastic through an annular slit die, usually vertically, to form a thin walled tube. Air is introduced via a hole in the centre of the die to blow up the tube like a balloon. Mounted on top of the die, is a high-speed air ring which blows onto the hot film to cool it. The tube of film then continues upwards, continually cooling, until it passes through nip rolls where the tube is flattened to create what is known as a “lay-flat” tube of film.
  • lay-flat or collapsed tube is then taken back down the extrusion “tower” via more rollers.
  • the lay-flat film is then either kept as such or the edges of the lay-flat are slit off to produce two flat film sheets 10 according to preferred embodiments of the present invention.
  • FIGS. 1 and 2 show a building 11 having footings 20 extending below the ground 12 and a concrete slab 21 which forms the base of the building 11 .
  • the concrete slab 21 is integrally formed with the footings 20 .
  • the footings 20 support the entire building 11 .
  • an inner frame 23 Extending upwardly from the concrete slab 21 is an inner frame 23 , which is connected to the concrete slab 21 via a bottom plate 22 . Extending upwardly from the footings 20 , approximately parallel to the inner frame 23 is an outer wall 24 . The outer wall 24 is spaced apart from the inner frame 23 , such that a cavity 25 exists between them. As the cavity 25 extends all the way around the building 11 , should any termites gain access to the cavity 25 from the ground 12 , then they may be able to attack a substantial portion of the building 11 .
  • the sheet 10 extends between the outer wall 24 and the bottom plate 22 so as to block off access to the cavity 25 above the level of the concrete slab 21 , creating a physical and chemical barrier against the penetration of insects.
  • the physical barrier is provided by the plastics material and the chemical barrier is provided by the insecticide dispersed through the plastics material from which the sheet 10 is manufactured.
  • the insecticide does not significantly leach from the plastic, but instead is retained so that the insecticide's activity is expressed through the plastics material. Because the insecticide's activity is expressed within the plastics material it does not require a substrate such as soil to leach into in order for the sheet 10 to work effectively.
  • the sheet 10 is more versatile and can be used in more varied applications than those of the prior art.
  • any contact or ingestion of the insecticide containing plastics material will kill the termites. This is because although the insecticide is tightly bound in the plastics material and is not dislodged by water, there is still enough insecticide available to deliver a lethal dose to an insect, which picks insecticide up upon contact with the sheet 10 . Only a tiny amount of insecticide is required to kill the insect.
  • a further piece of sheeting 13 extends between the outer wall 24 and the inner frame 23 on top of the sheet 10 and extends up the outside of the inner frame 23 .
  • This further piece of sheeting 13 is commonly referred to as “damp-proof course” and is primarily used as a moisture barrier to prevent moisture entering the cavity 25 above the sheet 10 .
  • the damp-proof course 13 may simply be a plastic sheet, ie. contains no insecticide.
  • the sheet 10 may be employed as the damp proof course because in a preferred embodiment, the sheet 10 is impermeable to water and can therefore act as a moisture barrier. There is therefore no need for the additional sheet 13 (as shown in FIG. 2 ) which saves time and cost in the building process.
  • the sheet 10 should be doubled over at the inner edge of the bottom plate 22 so that a portion of the sheet 10 extends up the outside of the inner frame 23 .
  • the sheet 10 if used also as the damp proof course is approximately 0.5 mm thick. Otherwise, the sheet 10 (as shown in use in FIG. 2 ) may be only 0.2 mm thick.
  • Weepholes 26 are provided periodically along the length of the outer wall 24 to allow for moisture between the sheet 10 and the damp-proof course 13 to exit the building 11 .
  • An advantage of the present invention is that because the insecticide is retained in the plastics material, that there will be extremely little or no insecticide leaking out of the weepholes 26 which could pose a human health risk.
  • the surfaces of the sheet 10 may be embossed so that there is friction between the surface of the sheet 10 and any bricks laid above or below the sheet 10 . This acts against any slippage occurring in the outer wall 24 and/or the sheet 10 .
  • the sheet 10 may have at least one smooth surface.
  • FIG. 3 shows the sheet 10 in a complete underslab application.
  • the sheet 10 is placed under the entire concrete slab 21 , above the footings 20 and across the cavity channel 25 to the outer wall 24 .
  • the sheet 10 may also extend at least partially up any penetrations 27 through the concrete slab 21 such that it forms a tight fit with an elongate member (not shown) in the form of a conduit, pipe, cable, etc extending through the penetration 27 .
  • the sheet 10 acts as a barrier against entry by termites to the building through any part of the concrete slab 21 and the cavity 25 .
  • the sheet 10 could be used in a variety of other applications in a building 11 , such as the perimeter of the concrete slab 21 , lining the inside of the penetrations 27 and any other critical joints, retaining walls and in any renovations or additions to the building 11 .
  • the sheet 10 When the sheet 10 is used in a complete underslab application or in a retaining wall situation, the sheet 10 also acts as a moisture barrier.
  • a replicated field trial conducted in the Northern Territory of Australia evaluated a plastic sheet product containing bifenthrin according to preferred embodiments of the present invention, as a barrier against field colonies of the Australian subterranean termites comprising Mastotermes drawiniensis and the mound building form of Coptoteres acinaciformis .
  • a range of bifenthrin concentrations was used in the assessment including untreated plastic sheet, and a sheet containing 0.1% bifenthrin. Each test was replicated ten times for each of the termite species giving a total number of replicates of twenty.
  • Samples of the sheeting were taken at 0, 1, 3, 6, and 12 months after application for under-slab simulated installations and at 0, 3, and 6 months after application for perimeter cavity simulated installations.
  • the under slab simulated conditions also investigated influence of soil type by including a clay soil and a sandy soil in contact with the sheet product.
