  • the operating methods are adapted according to the field of intervention.
  • a first solution is to glue the damping coating directly to the ground acting as a support, the ground generally being asphalt or concrete. This requires large quantities of glue and the periphery of these floors remains fragile and sensitive to detachment, for the reasons mentioned above.
  • sill also called a trench
  • a sill also called a trench
  • a larger quantity of aggregates is used in this solution, but the edges remain sensitive to tearing.
  • Said coating is poured and/or deposited on the support and in the stringers in order to have a greater resistance to tearing at the level of these edges because it benefits from a greater thickness in these areas.
  • this has the disadvantage of damaging the support located under the coating, because hollow stringers are necessary, and are made directly in the support.
  • the coating is removed or modified, it will also be necessary to restore and/or regroove the support before it can be used again. Thus the restoration of the support remains the responsibility of the operator, this representing a very significant cost.

  • the invention makes it possible to avoid repairs to the coating because the system guarantees the maintenance of the peripheries over its entire life, taking into account the quality of the materials such as stainless steel, brass, aluminum , recycled plastic and fiberglass mesh. This represents a financial gain since the peripheries of said coatings are currently covered up to three times during their life.

  • Coated and asphalt are, for example, materials chosen so that the border 11 has a specific geometric shape at the location where this border 11 is positioned.
  • this is a section made of recycled plastic, aluminum or any other material suitable for making a profile.
  • the use of a profile makes it possible, for example, to make the slot 10 during the manufacture of said profile rather than making it a posteriori with a router.
  • the slot 10 is for example placed on its upper part 12 or on its side part 13.
  • the slot 10 is made for example with a trapezoidal shape of the "dovetail” type, the shape of an inverted “T", a "U” slightly closed or straight on its upper part, or else all another form requiring the production of a slot 10 with a narrowed upper part and a lower part of increased size.
  • the slot 10 has for example a depth of a few centimeters, for example 2 centimeters and has for example a width of a size ranging from a few millimeters to a few centimeters.
  • the depth of the slot 10 requires a depth of the material in which the slot 10 is present at least greater than the depth of the slot 10, for example 4 centimeters if the slot 10 is 2 centimeters deep.
  • the slots can be made in all shapes, all depths and all possible widths depending on the configuration, the height of the floors or the nature of the supports.
  • the method according to the first embodiment also comprises a step of inserting a second fixing element 3 into the slot 10.
  • a mesh 3 which extends from the slot 10 towards the center coating 5. It has for example a width of more than twenty centimeters.
  • This is, for example, a fiberglass net, a polypropylene mesh, an aluminum expanded metal or a perforated sheet.
  • the mesh 3 makes it possible to maintain the coating 5 once in place thanks to its honeycomb shape.
  • a fixing mixture 14 contains, for example, epoxy adhesive, or a chemical sealant or any other sealing material, or even, depending on its dimensions, rubber mixed with polyurethane glue and fiberglass flakes.
  • the coating 5 is cast on the support 4 to be coated as well as above and below the mesh 3 and the slot 10. It comprises a damping lower layer 51 and an aesthetic upper layer 52 composed for example of Diene Monomer, polyurethane glue and fiberglass flakes.
  • the mesh 3 is taken in the coating 5, for example between the two layers or in one of the two layers.
  • a layer of glue 15 mixed with fiberglass flakes is applied to the old coating 16 in order to solidify the joint between the old 16 and the new coating 5, visible figure 10 .
  • the fixing device 1 obtained between the mesh 3 and the aggregates present in the slot 10 is taken in the mass of the covering 5 and makes it possible to fix the covering 5 to the support 4.
  • the slot is replaced by a succession of holes, the bottom of the hole of which is wider than the top in order to be able to insert pieces of mesh and the coating therein so that, after drying, the coating is fixed to the support by this device taken in its mass.
  • the holes are drilled in the support or in an added border and have a frustoconical shape.
  • the mesh pieces have for example a size of about 10 centimeters long, depending on the thickness of the coating, and a few centimeters wide.
  • the coating is for example a mixture of aggregates and fiberglass flakes.
  • the first fixing element 2 is directly fixed to the support 4. It is for example a set of chemical plugs, plastic or brass, nails, screws or other fixing elements. These first fixing elements 2 are placed over the entire length of the covering device 5 to be repaired and are spaced apart, for example, by about fifteen centimeters.
  • the method according to the second mode of implementation also comprises a step of inserting a second fixing element 3 fixed between the support 4 and the first fixing element 2.
  • a mesh 3 which extends from the first fastening element 2 towards the center of the coating 5. It has for example a width of more than twenty centimeters.
  • These are, for example, a fiberglass net, a polypropylene mesh, an aluminum expanded metal or perforated sheet.
  • the mesh 3 makes it possible to maintain the coating 5 once in place thanks to its honeycomb shape.
  • the coating 5 is then cast on the support 4 to be coated as well as over the mesh 3 and the first fixing element 2. It comprises a damping lower layer 51 and an aesthetic upper layer 52 composed for example of Ethylene-Propylene- Diene Monomer, polyurethane glue and fiberglass flakes.
  • the color of the new aesthetic layer 52 is for example different from the original color of the old coating 16 in order to indicate that the latter has been repaired.
  • Mesh 3 is taken from covering 5, by example between the two layers or in one of the two layers. Beforehand, a layer of polyurethane glue 15 mixed with fiberglass flakes is applied to the old covering 16 in order to durably solidify the joint between the old 16 and the new covering 5.
  • the fixing device 1 obtained between the mesh 3 and the first fixing element 2 is taken in the mass of the covering 5 and makes it possible to fix the covering 5 to the support 4.
  • the first fixing element 2 is an aluminum tube with a square or round section and a diameter of between 5 and 15 millimeters depending on the final thickness of the coating 5.
  • Aluminum is easily moldable and makes it possible to create any shape of covering periphery 5. It is fixed to the support 4 using fixing lugs 17 arranged at variable distances, for example nailed or screwed to the support.
  • a fiberglass mesh 3 is fixed between the aluminum tube 2 and the support 4, which makes it possible to cover this fixing device 1 with the coating 5 with a thin coating.
  • the mesh is in particular taken in the mass of the coating on its upper side and on its lower side, the coating being fixed vis-à-vis the latter since passing through the meshes of the mesh.
  • the first fixing element 2 is for example a rail or a thin aluminum border fixed to the support.
  • a mesh is fixed between the rail and the support and extends inwards.
  • a step of covering this fixing device is then carried out with the pouring of the covering.
  • the first fixing element 2 is for example a rail or a thin plastic border fixed to the support.
  • a mesh is fixed between the rail and the support and extends inwards.
  • a step of covering this fixing device is then carried out with the pouring of the covering.
