Definitions

  • the present invention relates to a method for providing a durable moisture seal within a body of concrete or the like by means of a deep impregnation agent, particularly within the superficial layer of a concrete body, such as a flooring, a wall or the like, possibly having a surface smoothing base, e.g. a self leveling so called float putty.
  • a deep impregnation agent particularly within the superficial layer of a concrete body, such as a flooring, a wall or the like, possibly having a surface smoothing base, e.g. a self leveling so called float putty.
  • the moisture may come from building moisture, i.e. moisture within and on the building material, which one, due to time pressure during the building job, has not afforded onself time enough to remove, or which one has simply "built in", because the building job has proceeded so fast that time has not permitted the old time months long or even half year long drying of the building.
  • the moisture may also depend on steam evaporation from ground bound water, particularly in connection with modern low house build ⁇ ings.
  • a very frequent source to moisture penetration into buildings is various leakages, floods etc.
  • the present invention aims at providing a method for the provision of a durable moisture barrier by means of a deep impregnation agent, on the application of which the above mentioned drawbacks are obviated at the same time as the efficiency of the impregnation is improved.
  • the superficial layer should be dried under a forced blowing on of a drying medium having a low relative humidity and a low partial vapour pressure, preferably hot compressed air, and under an optimal control of at least two of the following parameters which are essential to the drying result, viz.
  • an impregnation medium which has a high penetration ability and has the ability to form such a sealing gel that after the impreg ⁇ nation the difference in vapour pressure between the mouth of existing capillaries and deeper portions thereof is so small that the diffusion, depending on the vapour pressure difference, becomes neglectable or is set to a predetermined value.
  • the deep impregnation medium rquires at least some moisture to be able to form the sealing gel it may be found feasible, in some cases, as a preparatory step to the above mentioned drying step a) to soak the surface under preparation with water and permit the water to penetrate into the concrete to the required quantity and the required depth so that at least the moisture quantity required to form the gel should remain also after the drying step a) .
