Definitions

  • the invention relates to a method for producing flat coverings and to such a covering.
  • Repair of flat coverings is mostly performed by demolishing the upper part of the covering (tiles, cement support, sealing membranes, layers of thermally insulating materials, etcetera) and repairing with new material, usually similar to the existing one.
  • Repair methods are also currently known which add, on an appropriately prepared foundation, impermeable cement mortar composed of aggregates, hydraulic binders, additives, and elastomeric polymers, which can also act as a base for subsequent flooring, for example with tiled bonded by an appropriate binder.
  • the impermeable layer does not harden correctly and becomes rigid and brittle, losing the elastoplasticity characteristics that ensure, over time, preservation of waterproofing qualities.
  • a principal aim of the present invention is therefore to solve the described problems, eliminating the drawbacks of the mentioned prior art, by providing a method that allows to perform quick laying of a flat covering, for example for floorings.
  • an important object of the present invention is to provide a covering that can dry in an optimum manner and quickly.
  • Another object of the present invention is to provide a covering that is immediately walkable and has high-level compressive-stress resistance characteristics.
  • Another object of the present invention is to provide a covering that can be produced on site and at low costs.
  • the reference numeral 1 designates a flat covering for a previously prepared foundation 2 that is constituted by a base provided for example by means of a concrete casting.
  • the flat covering 1 is produced on site and entails the execution of a first step, during which a first layer of mix 3, having elastoplastic characteristics and providing adhesion to any foundation 2, is laid on the foundation 2.
  • the first layer of mix 3 is composed of aggregates, hydraulic binders, additives, polymers and water, which, in order to achieve the elastoplastic characteristics, need to produce, after laying, the optimum evaporation of the water contained therein.
  • the first layer of mix 3 thus comprises a cement mortar composed of a mix of water-hardening binders with inert materials with the addition of at least one polymer, such as a polyacrylic resin, and water, all this being provided while cold.
  • a cement mortar composed of a mix of water-hardening binders with inert materials with the addition of at least one polymer, such as a polyacrylic resin, and water, all this being provided while cold.
  • a microscopically perforated membrane 4 is laid having low water-permeability characteristics ahd good vapor-permeability characteristics.
  • the membrane 4 is constituted by polypropylene or other similar material and is densely perforated with perforations the diameter whereof is preferably smaller than 200 microns.
  • the membrane 4 is transparent with respect to the first layer of mix 3; by means of the fine perforation, the water contained in the first layer of mix 3 can in fact evaporate, thus allowing optimum hardening; however, the membrane 4 at the same time allows immediate walking.
  • the particular structural configuration of the covering allows, as soon as laying has been performed, to superimpose immediately thereafter a finishing layer such as, for example, a ceramic covering.
  • the method for obtaining the covering 1 then entails the laying of a second layer of mix 5 constituted like the first layer of mix 3.
  • the second layer of mix 5 can act as an adhesive for the finishing materials, such as for example ceramic coverings.
  • said covering has achieved the intended aim and objects, a method having been provided that allows to produce flat coverings by quick laying and at low costs; the membrane superimposed on the first layer of mix allows optimum transpiration; it in fact allows water evaporation and avoids, during the warm season, the formation of bubbles; this allows the first layer to dry in an optimum manner and in a short time; moreover, the membrane protects the impermeable layer and allows it to withstand considerable temperature ranges without damage.
  • the membrane becomes walkable as soon as laying has been completed.
  • the interposition of the membrane between the two layers of mix allows to increase the tensile-strength characteristics of the covering.
