Commercial Compaction Grouting

If your building site has loose, grainy soil or there are known sinkholes or voids under an existing building, we address those situations with a compaction grouting technique in CO, NM and AZ. Compaction grouting is especially effective when used on problem soil because it displaces loose soil and adds density to support the building above it. It can create a lift of any building that has settled because of problem soils.

In the compaction grouting process in CO, NM and AZ, we pump a viscous grout under high pressure into the ground. This causes the surrounding soil to compact. As the grout dries and expands, it pushes aside any loose soil which forms a grout column whose size varies based on the soil’s characteristics.

Grouting takes place in measured stages beginning at the bottom of a drilled shaft and moving upward through the soft and weak soil. On shallow applications, this process is reversed allowing a “cap” to form. This reverse method causes the upper portion of the treated area to become denser first, which helps contain the grout at the lower levels.

The pressure-treated soil has an increased uniformity throughout its entirety, especially when applied in a grid style. This uniformity increases soil stabilization and provides a solid support for buildings.

Compaction grouting’s greatest effect in CO, NM and AZ is seen in the weakest soil under a building.

When to Use Compaction Grouting:

  • Remediating soil during pre-construction
  • Lifting structures
  • Raising existing structures (roads, bridges, towers, etc.)
  • Filling subsurface voids and rock fissures
  • Filling sinkholes

Compaction grouting is sometimes used in conjunction with mud jacking.
