Consolidation Grouting

Consolidation of subsoil in dam construction and tunnelling

The injection materials are characterized by their excellent penetration capacity also in fine-particle, sometimes low-cohesive soil; they also show a good foaming behavior and therefore also fill smaller voids:

  • PU or silicate injection resins are preferable due to the self-distribution effect resulting from their expansion in pores and voids

Application by means

  • of Injection lances, often with sleeve technology,
  • Anchors or soil nails
  • Inflating packers / self-drilling anchors

Ground stabilization is frequently used in combination with rock mass stabilization, void filling or permanent sealing measures, less frequently in combination with anchor bonding
