Tunnel Face Consolidation

Stabilization of heading faces in tunnel or gallery driving; mostly for preparing further stabilization measures

For preventive stabilization of the heading face in tunneling or gallery driving, mostly for preparing further stabilization measures:

  • Stabilization to prepare for drilling and blasting
  • At short distance in case of unstable soil
  • Stabilization to prepare for pre-excavation grouting

Materials adapted to the tunneling method:

  • Use of TBM: stabilization systems such as e.g. silicate resins
    • suitable for cutting and planing
    • non-stick properties
    • fast strength development
  • Conventional tunneling such as drilling and blasting or excavation: mostly polyurethane systems
    • fast strength development
    • flexibly adjustable
    • waterstop and sealing at the same time

Heading face stabilization is usually part of extensive consolidation and sealing measures and plays an important role e.g. in pre-excavation grouting.

Products Used

  • Hybrid Injection System

    WEBAC® HIS

    • Consolidation Line

    WEBAC HIS is a hybrid injection resin used as a reactive component for large-volume cement grouting and holds National Technical Approval. It is characterized by rapid strength development and cures even underwater to form a stabilizing and sealing material. The resin is used to secure Foundation Pits and tunnel structures, as well as for subsoil stabilization and void filling.

  • Silicate Resins

    WEBAC® SILcompact M

    • Consolidation Line

    WEBAC SILcompact M is a non-foaming silicate injection resin with German Mining Approval. It offers excellent flow properties and cures very quickly into a compact material that can be cut and planed. The resin is used for stabilizing and sealing tunnel structures and in mining applications.

  • Silicate Resins

    WEBAC® SILfill

    • Consolidation Line

    WEBAC SILfill is a low-viscosity silicate injection foam resin. Even without contact with water, it forms a fine-celled foam with a high expansion ratio and cures quickly into a material that can be cut and planed. The resin is used for shield injection in the immediate vicinity of TBMs, as well as for subsoil stabilization and rock reinforcement.

  • Silicate Resins

    WEBAC® SILform

    • Consolidation Line

    WEBAC SILform is a silicate injection foam resin that foams and sets rapidly. It reacts with or without contact with water and cures into a pressure-resistant material that can be cut and planed. The resin is used for stabilizing and permanently sealing tunnel structures and in mining applications.
