The material which is the subject of the invention is in the form of a weft consisting of textile threads known for their toughness. The woven meshes will be dimensionally stabilized by any suitable method. Also in order to make the material impassable by underground termites, the son constituting the mesh will be coated with an abrasive powder firmly fixed by an adhesive, a polymerizable mastic or a resin.

The material according to the present invention is particularly intended for the protection of buildings and structures against invasion by underground termites.
Description
La protection des constructions contre les infestations par les termites souterrains nécessite l'interposition d'un écran entre le sol servant d'assise au bâtiment et l'édifice à préserver. The protection of buildings against infestations by underground termites requires the interposition of a screen between the ground serving as the building's base and the building to be preserved.
La présente invention consiste en la réalisation d'un matériau constitutif d'une barrière physique qui vient s'interposer entre le sol et les éléments d'ouvrage susceptibles d'être franchis par des termites souterrains. De part le monde, la technique la plus répandue consiste en l'usage de barrières chimiques réalisées par épandage au sol de pesticides liquides à raison de 5 litres par mètre carré environ. Plus récemment des barrières physico-chimiques présentées sous la forme de films de polymères tels que le polyéthylène chargés de pesticides ou sous la forme de résines polymérisables additivées de biocides ont été utilisées. Des barrières physiques composées de fins grillages métalliques sont en usage dans différentes parties du monde ainsi que les écrans de gravier calibré. The present invention consists in the production of a material constituting a physical barrier which is interposed between the ground and the workpieces likely to be crossed by underground termites. Worldwide, the most widespread technique is the use of chemical barriers made by spreading liquid pesticides on the ground at the rate of 5 liters per square meter. More recently, physicochemical barriers presented in the form of polymer films such as polyethylene loaded with pesticides or in the form of polymerizable additives containing biocides have been used. Physical barriers made up of thin metal fences are in use in different parts of the world as well as calibrated gravel screens.
L'ensemble de ces procédés présente différents inconvénients : Les barrières chimiques sont génératrices de pollution et leur usage est réglementairement restreint. Les barrières physico-chimiques sous forme de films nécessitent une mise en oeuvre longue et de nombreux raccords. All of these processes have different disadvantages: Chemical barriers generate pollution and their use is restricted by law. The physicochemical barriers in the form of films require a long implementation and many connections.
Les barrières physico-chimiques sous forme de résines polymérisables et chargées en insecticides sont susceptibles de générer des pollutions au moment de leur application et n'ont pas apportées la preuve de leur efficacité dans le temps. Les barrières physiques classiques, utilisant des grillages métalliques par exemple, manquent de souplesse et doivent être finement ajustées aux éléments de maçonnerie pour être 25 efficientes. Cette contrainte entraîne une installation longue et complexe. La présente invention consiste en la réalisation d'un matériau constitutif d'une barrière physique qui vient s'interposer entre le sol et les éléments d'ouvrage susceptibles d'être franchis par des termites, tels que les joints de dilatations, jonction des murs et des dalles ou de pieux de soutènement par exemple. La protection de l'ensemble de la surface sous et en périphérie de la 30 dalle et des murs de fondations est également possible grâce à la présente invention. Le matériau objet de l'invention se présente sous forme d'un tissage constitué de fils textiles connus pour leur ténacité. Les fils utilisés sont constitués de fibres de polymères naturels ou synthétiques dont notamment les fibres de polyester, polyamides, aramides, chlorofibres, polyéthylène ou polypropylène. Les mailles tissées ne devront pas excéder, avant leur traitement, 35 1 millimètre dans leur plus grande dimension mais pourront êtres de taille plus faible. Afin de conserver cette dimension maximale, les mailles lors du tissage seront stabilisées dimensionnellement par tout procédé adapté et connu de l'homme de l'art tel que notamment le nouage, le croisement, le thermoliage ou le collage. Le matériau ainsi obtenu n'est pas pour autant, en l'état, infranchissable par les termites souterrains. En effet, ceux-ci, par un lent travail 40 de cisaillement à l'aide de leurs mandibules, sont capables d'affaiblir la trame et de se glisser entre les mailles formées. Aussi afin de rendre infranchissable par les termites souterrains le matériau ainsi constitué, les fils constituant le maillage seront enduits d'une poudre abrasive fermement fixée par un adhésif, un mastique polymérisable ou une résine. Cette enduction des fils par une poudre 45 abrasive rend leur contact néfaste aux termites souterrains. Afin d'éviter de se blesser, les insectes cibles se détournent du matériau qu'ils ne franchiront pas. Le matériau abrasif le plus indiqué dans cet usage est, sans être exclusif, une poudre de pierre ponce dont la granulométrie varie de 10 à 500 microns. Cette matière est composée de particules à la géométrie telle que leur contact est néfaste aux termites souterrains. D'autres matériaux tels 50 que le corindon, la poudre de silex, la poudre de verre ou de particules métalliques conviennent également. Le support adhésif permettant de solidariser les particules abrasives à la trame textile est connu de l'homme de l'art qui peut choisir un adhésif, une résine synthétique, une enduction à chaud de polymères, de copolymères ou un matériau bitumineux pour obtenir l'effet désiré.Physicochemical barriers in the form of polymerizable resins and loaded with insecticides are likely to generate pollution at the time of their application and have not proved their effectiveness over time. Conventional physical barriers, using metal screens, for example, lack flexibility and must be finely tuned to the masonry elements to be efficient. This constraint results in a long and complex installation. The present invention consists in the production of a material constituting a physical barrier which comes interposed between the ground and the workpieces likely to be crossed by termites, such as expansion joints, joining walls and slabs or retaining piles for example. The protection of the entire surface under and around the slab and the foundation walls is also possible thanks to the present invention. The material which is the subject of the invention is in the form of a weave made from textile yarns known for their toughness. The son used are made of natural or synthetic polymer fibers, including polyester fibers, polyamides, aramids, chlorofibres, polyethylene or polypropylene. The woven mesh should not exceed, before their treatment, 35 1 millimeter in their largest dimension but may be smaller in size. In order to maintain this maximum dimension, the meshes during weaving will be dimensionally stabilized by any suitable method known to those skilled in the art, such as, for example, knotting, crossing, thermoling or gluing. The material thus obtained is not therefore, in the state, impassable by underground termites. Indeed, these, by a slow work of shearing with their mandibles, are able to weaken the frame and slip between the meshes formed. Also in order to make the material thus formed insurmountable by the subterranean termites, the threads constituting the mesh will be coated with an abrasive powder firmly fixed by an adhesive, a polymerizable mastic or a resin. This coating of the yarns with an abrasive powder makes their harmful contact with subterranean termites. In order to avoid injury, the target insects will turn away from the material they will not cross. The abrasive material most suitable for this purpose is, without being exclusive, a pumice powder whose particle size varies from 10 to 500 microns. This material is composed of particles with geometry such that their contact is harmful to subterranean termites. Other materials such as corundum, flint powder, glass powder or metal particles are also suitable. The adhesive support for securing the abrasive particles to the textile weft is known to those skilled in the art who can choose an adhesive, a synthetic resin, a hot coating of polymers, copolymers or a bituminous material to obtain the desired effect.
55 Le matériau selon la présente invention est particulièrement destiné à la protection des bâtiments et ouvrages d'art contre l'invasion par les termites souterrains. The material according to the present invention is particularly intended for the protection of buildings and structures against invasion by underground termites.
