- Underground Structural Linings – Contact grouting around precast and cast-in-situ tunnel, shaft and cavern linings to fill designed voids and establish continuous contact around the completed structure. Typical applications include tunnel cross passages, crossover caverns, passenger connection tunnels, shafts and underground hydro infrastructure such as transformer halls, turbine caverns and access tunnels.
- Unexpected Construction Voids – Targeted or high-volume filling of unintended voids resulting from incomplete concrete placement, complex geometries, construction defects or movement that has created separation around an existing structure.
- Decommissioning & Mass Void Filling – High-volume placement of flowable grout or other specified cementitious materials to fill redundant tunnels, shafts, chambers, pipelines and other underground spaces as part of permanent decommissioning works.
