Definitions

  • the present invention concerns a bituminous emulsion for cold waterproofing, elastic, modified with elastomers, that may be spray applied with a catalyst dissolved in water.
  • the emulsion according to the present invention comprising a percentage of bitumen in weight of 35% to 70%, modified with a percentage variable from 3% to 1 5% of elastomers (SBS) and spray applied with a two-nozzle spray, one for the emulsion and the other one for the catalyst, consisting of calcium chloride dissolved in water, so that the meeting of the two sprays on the surface to be treated obtains an immediate catalization.
  • SBS elastomers
  • the emulsion according to the present invention may be applied on any kind of structure, cement mortar, sheet- zinc, already existing sheaths, allowing to perform in short times waterproofing of great surfaces.
  • spray with two nozzles is provided with flexible pipes of appropriate width, thus allowing to leave the working unit downstairs of far from the application point. Due to the calcium chloride dissolved in the water, the sprayed product catalyzes as soon as it gets into contact with the application plane sticking strongly to the same, thus forming an elastic monolithic coat on whatever surface applied, of the desired thickness (suggested thickness: 4 mm ca.). The coat thus obtained is insoluble if it gets into contact with water, even a few seconds only after spraying, like in case of sudden rain.

Abstract

La présente invention concerne une émulsion bitumineuse d'imperméabilisation à froid, visqueuse, modifiée avec des élastomères, qui peut être projetée avec un catalyseur dissous dans de l'eau, comprenant de 35 % à 70 % de bitume en poids, un pourcentage variant de 3 % à 15 % d'élastomères (SBS). Ladite émulsion bitumineuse est projetée au moyen d'un pulvérisateur à deux buses, l'une pour l'émulsion et l'autre pour le catalyseur, qui consiste en chlorure de calcium dissous dans de l'eau, de manière à ce qu'on obtienne, à la rencontre des deux jets sur la surface à traiter, une catalyse immédiate.
