Chemical, Mineral & Cementitious Grouting

Pre-Injection and Post-Injection Technologies

Unexpected water ingress and poor ground conditions during mining and tunneling operations can cause significant problems for underground contractors. Pre-injection and post-injection technologies from BASF offer high-performing chemical and non-chemical products suitable for:

  • Water and crack sealing, void-filling
  • Strata stabilization, ground consolidation, structure repair
