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
