SikaFix®-210

Tough Polyurethane Resin for Injection Sealing and Ground Stabilization in Tunnelling and Mining

SikaFix®-210 is a fast-reacting polyurethane based resin with short gel times and high final strength.

  • High final strength
  • Foaming on contact with water (~ 3 times volume increase)
  • Very fast curing
  • Modular system with SikaFix AC-21 and SikaFix AC-21 SF
  • Easy application due to volume ratio 1:1
  • High penetration ability
  • Low initial viscosity
  • CFC- and halogen-free
  • Total solid*
* acc. to testing method of German Institute “Deutsche Bauchemie e.V.”

Areas of Application

SikaFix®-210 is used for permanent and durable injection sealing and ground stabilization of the headings in tunnel construction and mining. SikaFix®-210 is also used for stabilization of other loose rock faces, voids and unstable surfaces. It is suitable for injection in dry, damp and wet conditions, including sealing around water-bearing zones in rock, masonry dams and tunnel walls etc. SikaFix®-210 can be accelerated with SikaFix® AC-21 for waterstopping applications during construction works i.e. for unexpected water inrush. In situations with high water inrush and if a faster foaming action is necessary, the mixture of SikaFix®-210 and SikaFix® AC-21 can be further accelerated by the addition of SikaFix® AC-21 SF.

Application steps

MIXING

  • SikaFix®-210  is supplied in containers pre-batched according to the required mixing ratio of 1 : 1 parts by volume
  • Both components are mixed together on injection through a 2 C-injection pump, drawing each component directly from the original containers. The static mixer must be suitable to ensure that the mixture of comp. A and B forms a stable emulsion.
  • Use injection ports, lances or packers with a sufficiently large diameter and flow.

CLEANING OF EQUIPMENT
