Compaction Grouting

When Minimal Disruption around Existing Structures is Key

The Compaction Grouting method is a zero-spoil ground improvement technique that efficiently densifies and stabilizes loose granular soils with low load-bearing capacities. It is particularly effective in use around existing structures and in environments where access is very limited and near vibration-sensitive areas. It has also been proven to be one of the most effective ground improvement techniques for stabilizing underground voids and sinkholes.

How it Works

The Compaction Grouting Method works by creating bulb-like structures underground, one on top of the other, until a column of bulbs has been created. This is done by displacing the poor soils in stages and at depth by injecting a high-density cement mixture into the ground utilizing drilled casings. This method is especially effective in scenarios where ground improvement is required but where there will be no actual connection to the existing structure’s foundation, making it an unobtrusive solution to reinforcing soils without affecting existing structures.

Advantages

Zero vibrations or spoils
Rapidly increases bearing capacity
Minimizes soil liquefaction
Ideal for tight access sites
Deep foundation alternative: lower project cost

Technical details

  • Fill soils 
  • Liquifiable soils 
  • Loose granular soils 
  • Treat soils up to 20m deep  
  • Treat voids/sinkholes  

The densification of site soils starts with the injection of a mortar, usually with a high viscosity, and under pressure through an injection type of pipe. This injection of mortar is done at an exact flow rate, displacing the soil around the drilling tool and subsequently compacting it. This is done repeatedly with the pipe being removed in even lifts, producing a pillar of overlapping grout bulbs. As the bulbs expand and set, they consciously expand, densifying the surrounding soils in place.
