SikaInject®-311

(former TPH. ® RUBBERTITE)

3-part rubberlike, flexible acrylate resin

3-part, acrylate-/methacrylate-based water-expanding hydrogel that hardens to a rubber-like, flexible product.

  • Extreme low viscosity
  • Very good penetration into finest aggregates
  • Rubberlike flexible product
  • Good chemical resistance (many acids, alkalis, hydrocarbons)
  • Suitable also for damp proof courses in brickwork
  • Optional polymeric strengthening with SikaInject®-315 PS
  • Optional retarder SikaInject®-311 SL for extreme long potlife

SUBSTRATE PREPARATION

Surfaces of cracks, joints and voids need to be clean, free of loose particles, dust, oil and any other bond-breaking substances.

Any dirt must be blown out with compressed air.

MIXING

1. For curtain injection, brickwork, horizontal barrier (dpc) and ground stabilisation:

  • Empty part A2 completely into the part A1 container and mix for 3 minutes (part A1 + part A2 = Component A)
  • Fill part B2 into an equivalent 20 L container and fill with 20 L of tap water - mix for 3 minutes (part B2 + water = Component B)
  • Components A and B prepared in this way are ready-for-use, pump with a 2-C pump in a ratio 1:1 parts by volume directly from containers
 

2. For crack injection and injection hoses

  • Empty part A2 completely into the part A1 container and mix for 3 minutes (part A1 + part A2 = Component A)
  • SikaInject®-315 PS is used instead of water in Component B
  • Make sure that component B2 (hardener salt) is completely dissolved in SikaInject®-315 PS
  • Therefore: half-fill container of part B2 with tap-water and shake until part B2 salt is completely dissolved
  • Fill this salt-solution into container of SikaInject®-315 PS and mix for 3 minutes (part B2 + water + PS = Component B)
  • Components A and B prepared in this way are ready-for-use, pump with a 2-C pump in a ratio 1:1 parts by volume directly from containers.

Activated components A and B remain stable for approx. 5 hours (depending on temperature).
