What is Compaction Grouting?

Compaction grouting is a process of stabilizing the soil prior to construction. This is accomplished by drilling to a pre-determined depth below the surface and injecting a low-slump, low-mobility soil/cement grout into the ground. The grout mixture creates a pocket deep below the surface that grows as more grout is forced into the ground. As the pocket of grout expands, it compacts the soil around it, causing it to become more stable for the building. In almost all cases, several “stacked” pockets of grout are created, stabilizing the soil over a depth that will support the intended structure.

Compaction Grouting Installation

Compaction grouting is typically performed in a sequenced operation over a pre-defined grid pattern. At each location, the casing is driven or drilled to design depth and grouting is performed from the bottom up in short lifts of typically 1-2 ft until a predetermined refusal criterion (maximum pressure, maximum grout volume, or maximum structural surface settlement) is met. The grout pipe is then raised to the next stage and the process is repeated to form a grout “column”. Grout column installation in a primary/secondary /tertiary sequence displaces and thus densifies the intermediate soils.

Compaction Grouting Applications

Because compaction grouting strengthens the ground, it is used to stabilize underground structures for pipes and tunnels. It can also stop foundation settlement, increase bearing capacity of soils, and treat sites with sinkhole activity.
Compaction grouting can be applied to the following subsurface conditions.
  • Sinking or settling structures
  • Voids
  • Sinkholes
  • Loose or weak soils
  • Poorly compact fills
  • Collapsible soils
  • Above or below water tables
  • Constricted areas

Compaction Grouting Advantages

Compaction Grouting can control the settlement of foundations on existing homes; stabilize subsoils that are determined to be weak before beginning construction on a new home or structure, and lifting existing foundations that have settled.

Here are some advantages of Compaction Grouting:

  • Rapid installation
  • No spoil generation
  • Can be accomplished in restricted access situations
  • Structural foundation connections not required
  • Low mobility grout rheology allows for precisely controlled placement
  • To increase bearing capacity
  • To arrest or reduce foundation settlements
  • Mitigation of liquefaction potential
  • Sinkhole remediation
  • Stabilization of karstic formations

Compaction Grouting Limitations

  • Not appropriate for low permeability soils (i.e., clays).
  • Not suitable in zones where limited soil cover can result in unacceptable heave.
