Base

  • The drill hole temperature is -10°C…+5°C. Snow and ice are melted from the drillhole.
  • The drill hole has been flushed with pressurised water and, if necessary, blown with compressed air.
  • The bold holes must be clean, solid and dust-free.

Priming

  • The drill hole is not primed

Work instructions

  • The work area must be completely protected from wind, sun and rain.
  • During the bolting and while the plaster is hardening, the air and drill hole temperature must be < -10°C.
  • A sack (25 kg) is mixed with 4.7–5.0 litres of cold water. If the product will be pumped, add 18–20% of water of the weight of the dry product. The bolting plaster has the correct amount of water when the it does not drain out of a vertical drill hole.
  • The amount of water must be as instructed in the product card. Deviating from the recommended amount of water reduces the bolting plaster’s strength properties, increases the bleeding risk, affects the bolting plaster’s strength development, and weakens workability.
  • Mix the bolting plaster carefully into a uniform paste (using a horizontal pan-mixer or continuous mixer).
  • The bolting plaster is pumped into drill holes in the rock with a suitable plaster pump. The bolting plaster must fill the drill hole completely.
  • The bolting plaster must be protected from mechanical disturbance during its strength development.
  • Workable for about one hour after adding water.
  • When finished working, wash to tools immediately with water.
  • Remove any dried Winterbolting plaster mechanically.

Other considerations

  • Work is performed according to the infraRYL instructions.
