What is Compaction Grouting?

The process involves drilling a pilot hole to a required depth. A casing is placed in the pilot hole and connected to a grout pump. Depending on the application, low, medium, or high mobility grout is then injected into the hole at intervals and pressures as directed by the Geotechnical engineer. The injection process displaces loose soils and fills voids with solid grout, leading to improved soil density and stability for any structure above.

Compaction grouting is an economical option compared to other approaches and can be accomplished where access is complex and space is limited.

  • Can be done in tight spaces
  • Can be done during all seasons
  • Can reach depths traditional methods can’t
  • Can adapt to existing foundations and structures
  • Can work in variety of soil conditions
