Definitions

  • the invention relates to a method for drying wall walls and an applicator of water-repellent solution for the implementation of said method. It will find its application in particular in the building industry for the treatment of bricks, concrete, wood and other materials against humidity, fungi, merules, saltpetre and others.
  • microcracks or capillaries in the material promotes over time the propagation of water by capillary action in the heart of the porous mass which, in this way, becomes contaminated over time.
  • a PVC film which acts as a screen and which is interposed between the wet environment and the building element to be protected.
  • This device is effective but nevertheless requires to be put in place at the time of construction, which excludes its use in old buildings which do not have it.
  • Impregnation to the core remains a delicate operation, especially if the support is already contaminated by humidity, the main reasons for failure are as follows.
  • This preparation essentially consists in making a certain number of holes made in the support which are intended to allow the injection, diffusion and impregnation of the water-repellent solution at heart, in the material to be treated.
  • the drilling of the holes must be dimensioned in a manner adapted to the thickness of the material to be treated and distributed according to a density also adapted to the needs.
  • the contact of air with the water repellent solution during impregnation causes evaporation of the most volatile products, which results in a modification of the composition of the water-repellent solution and a decrease in its effectiveness at the end of treatment.
  • the compressor which limits its scope to well-equipped professionals.
  • the injection into the different holes is carried out simultaneously, which does not make it possible to control the dosage of the injection carried out in each of them and, for example, the distribution of the water-repellent solution may be totally uneven in the material to be treated.
  • the injection time is relatively short, at most of the order of a few hours.
  • the high pressure used should, in theory, compensate for the short impregnation time to spread the water-repellent solution in the porous mass.
  • this is the main cause of failure.
  • the short time used for impregnation is not enough for the water repellent to drive out the water and fix itself in its place. Water often took decades to soak the wall and it is not in a few hours, even under pressure, that the water-repellent solution can spread through the capillaries and especially the finest.
  • the present invention aims to provide a solution to the various drawbacks mentioned above.
  • the implementation of the drying process requires only a small auxiliary material, which facilitates its use, lowers its cost price and extends its field of application to personnel with little experience.
  • the present invention offers a solution which provides a global treatment of the porous mass to be treated.
  • Another object of the present invention is to present a water-repellent solution applicator which is particularly suitable for implementing the drying process, said applicator being economical, very easy to use and particularly precise in measuring the dosage of the quantity of water-repellent solution injected.
  • the method of drying wall walls by injection, impregnation and diffusion of water-repellent solution, such as a synthetic resin, in which various holes are made in the area of the wall wall to be treated, is characterized in that one injects , in each hole, a controlled dose of water repellent solution.
  • the applicator of water-repellent solution in a porous mass such as a wall wall is characterized in that it consists of: - a sealed tank intended to contain the solution water repellent, - a water repellent solution flow pipe connected to the tank, - A tight connection connecting to the holes made in the porous mass with said pipe.
  • the present invention relates to a method for drying wall walls, by impregnating water-repellent solution, as well as an applicator for water-repellent solution for implementing said method. It will find its application in particular in the building industry for the preservation or repair of building elements, such as bricks, cement, concrete, wood or other materials.
  • the main disadvantage of this treatment method is that there is no local control of the impregnation of the wall with the water-repellent solution. At most, an overall control of the injected solution can be carried out, however the operator cannot determine whether the distribution of the water-repellent solution in the wall is uniform. Numerous previous experiences show that, precisely, there is a poor distribution of the water-repellent solution and that consequently, the expected results are not achieved.
  • the support is prepared by making in the latter a certain number of holes which will constitute the cavities intended to be filled with water-repellent solution and which will facilitate injection, impregnation and diffusion to core of the material by said water-repellent solution.
  • the dimensions of the holes, their depth and their density must be adapted to each case.
  • the main characteristic of the present invention is that a controlled dose of water-repellent solution is injected into each of the holes.
  • an airtight connection is established between the reservoir of water-repellent solution and the hole, the fluid contained in the reservoir is caused to flow towards the hole and control is made.
  • impregnation by measuring the volume of water-repellent solution remaining in the tank. More sophisticated flow measurement techniques could be used, however the control of the volume of water-repellent solution remaining in the tank is satisfactory.
  • This pressurization could, for example, be obtained by injecting compressed air into the sealed tank.
  • This technique is particularly interesting because it does not require the permanent use of a compressor while offering the advantages of a pressurized, therefore faster, injection of the water-repellent solution into the material to be treated.
  • the impregnation, injection and diffusion time of the water-repellent solution for each of the holes can last from a few hours to several weeks.
  • the present invention makes it possible to guarantee a very high efficiency of the treatment.
  • the process of the present invention is very competitive since it does not permanently require the presence of an operator to monitor the process which is slow, an episodic control of the volume injected is sufficient to carry out the operation.
  • no heavy equipment must be used permanently, which considerably reduces fixed assets.
  • Figure 1 shows schematically a preferred embodiment of an applicator of water repellent solution in a porous mass, according to an implementation of the wall wall drying method of the present invention.
  • the porous mass (1) which is in the form of a wall has a number of holes (2) which have been made therein to allow the impregnation of water-repellent solution.
  • the applicator (3) comprises a sealed reservoir (4) intended to contain the water-repellent solution sheltered from air. Indeed, as emerges from the previous drying process, the impregnation time can be substantial and, under these conditions, it is imperative to protect the water-repellent solution against the evaporation of its volatile substances.
  • the applicator (3) also comprises a pipe (5), preferably flexible, for the flow of the water-repellent solution connected to the reservoir (4).
  • the applicator (3) also comprises a tight connection (6) for connecting the hole (2) made in the porous mass (1) with said pipe (5).
  • the tank (4) is provided, for example in its upper part, with a hooking system (7) which allows it to be fixed in height in order to authorize the flow of the water-repellent solution in the hole (2 ) by gravity.
  • the filling of the reservoir (4) can be carried out at its upper part by means of an orifice closed by a tight plug (8).
  • FIG. 2 shows schematically in section the construction details of the plug (8) for closing the filling port of the tank (4).
  • a valve (9) is arranged in the center of the plug. This valve (9) allows the introduction of compressed air into the tank in order to pressurize the water-repellent solution.
  • the introduction of compressed air can be carried out using a simple hand pump or a compressor.
  • a pressure gauge (10) can be installed on the tank (4) in order to control the pressure prevailing in its interior enclosure at any time.
  • the tank body (4) is conical and made of a transparent material on which are placed graduations (11) which facilitate the measurement of its content.
  • the conical shape is preferable because it makes it possible to increase the sensitivity of the measurement of the volume remaining at the end of impregnation. It is therefore possible to measure with great precision the volume of water-repellent solution injected.
  • the lower part of the tank (4) comprises a tap (12) which controls the communication of the tank (4) with the drain pipe (5).
  • FIG. 1 A first model of tight fitting (6) is illustrated in FIG. 1 according to which the tight fitting is formed by a rubberized outer casing (13) of conical shape, which allows a tight fitting of the fitting (6) in the hole (2 ).
  • Figure 3 shows schematically a preferred embodiment of a sealed connection.
  • This tight fitting (6) is in the form of a tube (14) crimped on the drain pipe (5) at one of its ends and which comprises, at the other end, a stop (15) .
  • an expandable spacer (16) for example made of a rubberized material.
  • the tube is threaded and a nut (17) is screwed onto said thread.
  • the nut (17) is applied to a washer (18) which itself exerts longitudinal pressure on the spacer (16) pinched between the stop (15) and the washer (18).
  • the spacer (16) is caused to expand, which thus ensures a tight connection between the drain pipe (5) and the hole (2) made in the wall wall. porous (1).
  • the applicator of the present invention is reusable.
