    Method for the treatment and eradication of building pests, in particular fungi such as marigold
    The present invention relates to a method for treating pests of buildings, in particular lignivorous fungi such as the merule.
    The merule gathers several species of mushrooms, the most common of which is Serpula lacrymans. It is a lignivorous fungus whose appearance inside a building is related to the humidification of the wood. A confined atmosphere also promotes growth. It is known that a humidity of between 22 and 40% and a temperature of between 20 and 26 ° C. are optimum conditions for the development of the merule.
    The development of the merule is divided into two phases. The first phase is vegetative formation. During this phase, germination of the spore produces a white swab mass called primary mycelium. Different primary mycelia will then fuse and form the secondary mycelium. If the environmental conditions are favorable to it, the secondary mycelium evolves in white wooly masses of up to several cubic meters. Mycelial cords are then formed more and more thick and branched.
    The next phase is the fruiting phase between two individuals from which will be born a new mycelium that will produce one or more carpophores. These - can reach two meters and are yellow-brown in color. They are visible on the wood and contain spores used to reproduce the species by dissemination.
    The fungus hydrolyzes cellulose and wood lignin for food, which produces water and increases the moisture content of the wood. The consistency of the wood becomes dry and brittle. This is called "cubic rot".
    It should be noted that in the adult stage, the fungus penetrates plasters, bricks and masonry to continue its evolution. It can reach up to four meters per year.
    Conventional methods of treatment of the merule involve injecting into perforated wells in the masonry anti-fungal products after baring the walls. These processes comply with the Qualibat 1532 certification establishing the technical rules for the curative treatment of wood and buildings against woody fungi including the merule in particular.
    The disadvantages of the processes using chemicals such as fungicides are, on the one hand, their limited effectiveness and, on the other hand, the toxicity of the products used for man and for the environment.
    The object of the present invention is to propose a method of eradicating mushrooms proliferating inside buildings, in particular the merule, which is effective, that is to say, without reappearance of the mushroom after the implementation of the method. on the perimeter treated even for a long time whether or not there was a chemical injection stage.
    To this end, the invention relates to a method for treating and eradicating mushrooms proliferating inside buildings, comprising the following steps of: a) Exposing the masonry to be treated by removing any covering, where appropriate, b) Sweeping of the masonry to be treated by a heat source producing a temperature of at least 200 ° C, c) Manual removal of the visible myceliums on the masonry to be treated and on the masonry joints, d) Purge of the woods embedded in the masonry to be treated if necessary, e) Drilling of one or more groups of wells in the masonry to be treated, in the following manner: a so-called well is pierced and then between five and ten wells are drilled around the well central to form said well array, each well being spaced apart from an adjacent 15-20 cm well and having a circumference of between 18 and 20 mm and an included depth between three-quarters and four-fifths of the thickness of the masonry to be treated,
    Characterized in that it further comprises, following the step of drilling wells, a step of: f) Inflammation of each well one after the other until the appearance of flame output of adjacent wells the flame being maintained for 1 to 3 minutes, preferably 2 minutes, at a temperature of at least 200 ° C.
    The combination of the characteristics of the distance between the wells, the depth of each well as a function of the thickness of the masonry, the temperature resulting from the ignition in each well and the duration of the application of the flames per well allows eradication of the fungus and its spores, without subsequent reappearance, on the masonry thus treated. The process steps are performed sequentially in the order (a) to (f). The process meets Qualibat 1532 certification in steps (a) through (e).
    According to one embodiment of the invention, the fungus is the merule, preferentially Serpula lacrymcms.
    According to one embodiment of the invention, in a grouping of wells, these are drilled to form at least one polygon, each polygon thus comprising a well in its center and between five and ten sides and vertices and each vertex being represented by a well.
    The method may further comprise a step (g) of injecting a treatment product, such as a synthetic or natural fungicide, into the wells and / or spraying such a product on the surface of the well. masonry. For example, the treatment product may be an aqueous solution of boron salt. This injection step is then performed after the step (f) of ignition of the wells. It should be noted that the fungus is eradicated from the treated masonry when this step is absent from the process.
    Preferably during the ignition step of each well, the flame is kept inside the well for about two minutes. The flame is visible at the exit of an adjacent well for 10 to 20 seconds. This ensures that the fire propagates in the mycelial network and spreads along the cords of the fungi. Thus, all the organs of the parasite is burned.
    Inflammation of the wells is advantageously carried out by means of a torch, for example propane-fueled and provided with an 18 mm wick.
    Preferentially, the wells are drilled in the joints of the masonry.
    It is advantageous to pre-mark the wells with a bright color. Similarly, it is necessary to implement, following the implementation of the method according to the invention, a monitoring step of a few hours (two or three) to ensure no fire.
    In Fig. 1 is shown schematically the result of the step of drilling wells in a masonry to be treated.
    In accordance with the 1532 Qualibat certification, the Ma masonry to be treated was laid bare by the removal of any covering (plaster, paneling, etc.). Wells, such as the Pu well, are drilled in the joints Jt. In this embodiment, seven wells form a polygon PG1 with six sides and six vertices. It still has a well drilled in its center. This polygon represents a first group of wells Gl.
    Next to this hexagon, a pentagon PG2 with a central well is also formed by drilling 4 other wells. This polygon PG2 represents a second group of wells G2. Polygons PG1 and PG2 have a common well here.
    Each polygon vertex is therefore represented by a well of a depth P corresponding to 3/4 to 4 / 5ths of the thickness E of the masonry, in this case the wall to be treated. The circumference of each well is 18 mm, an opening sufficient for the insertion of the stem of a torch.
    The wells are separated from one another by a distance of 20 cm and are distributed over the entire polygon assembly masonry.
    Once wells drilled, a torch is used to burn the mushroom network inside the wall itself. To do this, the burner burner tip is inserted into each well. The flame created in each well for a suitable duration allows the inflammation and destruction of the fungus network throughout the area of the masonry involved in the treatment.
