Definitions

  • the present invention relates to methods for the installation of a waterproofing coating, in particular on back roofs, terraces or back structures such as a bridge.
  • This bonding or bonding is generally obtained by cold or hot bonding or using various fixing devices such as nails, screws, etc.
  • this bonding is partial, that is to say that it only connects the coating to the support on part of the corresponding surface of this coating by means of strips or dots of glue.
  • This partial bonding allows, on the one hand, to avoid propagating in the thickness of the coating, the major part of the forces caused by the movements and the deformations of the support, such as cracks and, on the other hand, to allow dry or humid air present under the coating to move to various outlets to avoid the formation of blisters due to the presence of this air blocked between the support and the coating itself.
  • These coatings comprise one or more layers arranged one above the other above the protected support, the single or lower layer partially glued to the latter being formed of bituminous sheets which are arranged on the surface to be protected so that their neighboring edges overlap.
  • the surface of the bituminous sheets of the lower layer of the coating, intended to be opposite the support or lower surface is free of screen and the partial bonding of these sheets can be carried out either by pouring hot or cold glue, tette only molten bitumen, by plates, by lines or by points on the surface to be protected and by simply covering the latter with the lower surface of the sheets, either by heating zones with zones previously materialized or not from the lower surface of the sheets to cause them to be thermo-welded on the support at these heated zones.
  • the screen is first of all placed on the surface to be protected and the bituminous sheets are bonded to the support through the openings made by this screen, either using cold glue. or hot spread on the latter which can then be made of paper, either by heating with a torch the lower surface of the sheets and, in this case, the material used for the screen must be flame resistant, such as for example cardboard. asbestos, mineral nonwoven fabric or thin metal foil.
  • each bituminous sheet has on its lower surface, a perforated screen placed at the time of their manufacture, this screen being able to be made of a flame-resistant material in order to allow its heating using a torch and thus heat sealing the sheets on the surface to be protected through the perforations of the screen (cf. for example FR-A-2 478 709).
  • the sheets are each provided on their lower surface with a continuous screen without perforations on which are distributed pads of a self-adhesive or thermo-adhesive sheet, the sheets not adhering to the support. than to the right of these studs.
  • the screen In the case where the glue used is thermo-adhesive, the screen must be made of a material which resists heat so as to be able to withstand the flame of a torch during direct heating of the studs.
  • the coatings using hot or cold glues have the disadvantages due to the use of these glues and, in the case where the glue has to be poured onto particular areas of the support, the regularity of the partial gluing obtained can hardly be reproducible. .
  • the installation of the lower layer will initially require covering the bituminous sheets of the surface to be protected by unrolling these sheets from rollers and, in a second step, removing the protective films from self-adhesive pads if such pads are provided, forming strips or spots of glue on the surface to protect or to heat partially or completely with a torch the lower surface of the bituminous sheets.
  • the material of the perforated screen provided on the lower surface of certain bituminous sheets does not save a partial destruction of the screen on a particular area, for example with a torch, in order to eliminate this screen from the edges of end of the sheets at the time of their installation to allow the entire surface of these end edges to be bonded to the support and thus ensure effective protection of the latter at this level.
  • the object of the invention is to remedy these drawbacks by providing a method of fitting a waterproofing coating comprising at least two superimposed layers which is simple and quick to apply while producing a coating that is partially and effectively linked to the support which it protects at regularly distributed zones, some of these connecting zones possibly being chosen at the time of laying the covering.
  • the subject of the invention is therefore a method for installing a waterproofing coating, in particular for roofs, terraces or civil engineering structures such as bridges, comprising at least two layers superimposed on a surface to be protect from a support, the first layer of this coating close to the surface to be protected being formed of at least one bituminous sheet having on its surface oriented towards the support or lower surface, a screen providing openings made of a material which does not 'is not likely to be degraded under the action of heat up to a temperature of about 200 ° C but which is likely to be degraded by the application of a flame, characterized in that it covers the surface to be protected of the support with at least one of said bituminous sheets to form the lower layer of the coating in such a way that the screen of this sheet is facing the surface to be protected and in that it is glued hot on this layer lower, one of uxth layer so that the heat input released during the establishment of this second layer achieves bonding on the surface to be protected from the sheet by adhesion to the support of the
  • the waterproofing coating comprises a lower layer of bituminous sheets 2 covering the surface of a support 5 and an upper layer 3 formed of hot-poured asphalt on the lower layer 1 of sheets 2 .
  • the support chosen here by way of example is made of concrete or cement, but, as will be described below, the nature of the material of this support can be diverse.
  • the sheets 2 based on a conventional bituminous composition in this technique comprising for example fillers and additives, each have the shape of a strip, preferably from a roll and are each arranged by extending roughly parallel to each other so that their neighboring side edges overlap over their entire length, a side edge 4 of each sheet covering the corresponding edge 5 of an adjacent sheet and the edge lateral 5 opposite that of this sheet being covered by the corresponding edge 4 of the other adjacent sheet.
  • the lower layer 1 provides a lower surface which extends continuously opposite the surface to be protected from the support S.
  • the set of lateral surfaces in contact with each other of two adjacent sheets that is to say a zone 6 free of screen from the lower surface of the edge 4 of a sheet and the corresponding covered area 7 of the upper surface of the respective edge 5 of the neighboring sheet, are continuously bonded together by heat welding the bituminous composition of these sheets by virtue of the heat supplied by the upper layer 3 hot when it is put in place.
  • each sheet is provided on its lower surface with a screen which extends over the length of this surface from the inner limit of the lateral zone 6 of the sheet to the edge opposite this zone or covered edge. .
  • the screen 8 comprises a part 9 free of openings or perforations having roughly the shape of a strip, while over its entire remaining surface, this screen cleaning openings on the lower surface of the sheet, in the form of perforations 10 through roughly each of which this sheet is connected to the support S by heat welding of its bituminous composition on the latter to thereby achieve a partial bond or "semi-independent" of each sheet on the support, this connection being reduced to a part of the lower surface of the latter, delimited by at least part of the perforations 10 formed on the associated screen 8.
  • Such a screen is advantageously made of a material such as smooth or crepe paper, a veil or a glass fabric, a nonwoven, a film of synthetic material or, preferably, polypropylene, such a material having for reasons which will be explained below, the advantage of not being degraded by fusion during the addition of heat due to the establishment of the upper layer of the coating, that is to say up to a temperature d 'about 200 ° C but which, on the contrary, is easily degraded by direct contact with a flame, such as the flame of a torch.
  • a material such as smooth or crepe paper, a veil or a glass fabric, a nonwoven, a film of synthetic material or, preferably, polypropylene, such a material having for reasons which will be explained below, the advantage of not being degraded by fusion during the addition of heat due to the establishment of the upper layer of the coating, that is to say up to a temperature d 'about 200 ° C but which, on the contrary, is easily degraded
  • the perforations 10 formed in each screen 8 preferably each have an approximately circular shape with a diameter of about 3 cm in such a way that the opening formed by each perforation is not too small in order to ensure an effective connection with the surface to be protected, or too large in order to limit the contact surface, the total surface of these perforations representing approximately 15% of the surface of the screen itself.
  • the latter is also made of a material which is weakly permeable or, preferably, impermeable with regard to the hot bitumen of the sheet, that is to say the bitumen of this sheet softened by heat.
  • the sheets 2 Before being laid, the sheets 2, the thickness of which may preferably vary between 1 and 5 mm approximately, are generally presented in rolls and, for this purpose, they are provided at the time of their manufacture with a film (not shown) made of a material which does not adhere to cold bitumen. This film is placed on the upper surface of the sheets 10 leaving on their lateral edge adjacent to the corresponding screen part 9 without perforations, a bare strip free of screen which will form in a coating, the covered zone 7 described above. .
  • this strip 7 is intended to allow efficient heat-sealing of its entire surface on the lateral zone 6 covering the lower surface of the corresponding adjacent sheet of a coating which, for the same reason, is free from screen 8 at manufacture.
  • the sheets thus produced are suitable for being rolled up on themselves without fear of the sticking together of the turns formed in the measure where the screen 8 and the bare area 6 adjacent to each roll sheet comes into contact with the film provided on the surface.
  • the portion 9 without perforations of this screen being of a width at least equal to that of the second bare area 7 formed on the upper surface of the sheet in order to completely cover this area.
  • This film does not appear on any coating sheet of the Figure, because the material in which it was chosen, was degraded by fusion during the supply of heat from the hot pouring of the upper layer 3 of asphalt so to ensure effective thermo-adhesion or thermo-welding of all of the surfaces in contact of the two layers with one another.
  • Such a material is for example polyethylene which is moreover suitable for waterproofing coatings with an upper layer of bituminous sheets bonded with hot bitumen spread on the lower layer.
  • bituminous sheets of the invention can also comprise, in a manner known per se, one or more reinforcements, chosen from conventional materials such as a veil or a glass fabric, a burlap or a polyester nonwoven ...
  • the method of placing the illustrated coating firstly comprises covering the surface to be protected from the support S by means of the sheets 2, the latter being simply unwound on this surface by superimposing the edges of neighboring sheets as described above.
  • the lower layer 1 being thus formed, the upper layer 3 of asphalt is then hot poured over the entire surface.
  • This process is particularly advantageous insofar as the surface to be protected is never in contact with bitumen spread hot or with the flame of a torch, which makes it possible to provide such a waterproofing coating on a support material. likely to be degraded by one or other of these heat sources such as polyurethane foam or other plastics, wood or other materials such as insulation materials.
  • the sealing layers constituted by bituminous sheets comprising reinforcements
  • the screens 8 each include, in line with these overlaps, the screen portion 9 without perforations which extends opposite the surface to be protected thereby preventing at this level the sticking of the corresponding sheet on the surface to be protected.
  • the upper surface of the bituminous sheets can be coated with a film capable of being degraded by direct application of a flame, for example a paper or polypropylene film, these sheets then being adapted to be used in a waterproofing coating, the upper layer of which is bonded by heat-welding with a torch, so that the film on their upper surface is degraded by the latter when the upper layer is bonded.
  • a film capable of being degraded by direct application of a flame for example a paper or polypropylene film
  • the entire upper surface of the sheets may comprise, in a manner known per se, a granular mineral material such as fine sand, talc or slate powder, which, like the film previously described , helps to avoid sticking of the turns between them of the bituminous sheets arranged in a roll while allowing the upper layer of a coating to adhere to this surface by heat-welding the bituminous composition between these mineral grains.
  • a granular mineral material such as fine sand, talc or slate powder
  • the upper layer of the coating can be formed from conventional bituminous sheets which completely cover the upper surface of the lower layer, this upper layer being bonded to the whole of this upper surface, for example by hot gluing with using molten bitumen or by heat welding using a torch.
  • the addition of heat resulting from the installation of an upper layer of bituminous sheets causes the bonding of the lower layer on the surface to be protected. .
