In the fight against water infiltration, Stevanato had the chance to specialize also in the waterproofing with polyurea.
For this purpose, it uses one of the most modern existing materials: a resin-based sheath that is used by spraying, is rapidly hardened, is waterproof and contains no solvents.
This waterproofing can be hot sprayed with suitable pumps or applied cold using a roller, brush or sprayed.

 

The waterproofing with polyurea is perfectly adherent, therefore achievable on difficult surfaces such as:

  • steel
  • concrete
  • reinforced concrete
  • terracotta
  • iron
  • bituminous sheaths
  • stoneware
  • wood
  • grit tiles
  • spray polyurethane or panels
  • polystyrene

The polyurea is applied by using a high pressure and high temperature bi-mixer pump. As soon as the mixture is sprayed, it catalyzes within a few seconds.

During the waterproofing operations with polyurea, the application surface is checked beforehand and it must preferably be rough and dry (maximum humidity 15%). Otherwise, it is prepared in order to obtain a perfect adherence of the new applied material, such as by spreading a primer coat before the application, with the exception of the old bituminous sheaths.

The fields of application of waterproofing with polyurea are:

  • walkable or drivable plains
  • outdoor and indoor industrial floors
  • primary containment tanks for purifiers, underground or above ground
  • anticorrosive coating for secondary containment tanks for special plants
  • sidewalks, tunnels, road bridges
  • open-air fluvial channels
  • swimming pools and hot tubs
