COMPACTION GROUTING
Compaction grouting involves injecting a very stiff homogeneous grout mix under relatively high-pressures and at low injection rates to subsurface locations in pre-designed patterns in order to displace and compact soils.

FOUNDATION DESIGN
Know exactly what type of support you will need for the foundation supporting your structure.
PROCESS
An injection pipe is inserted, typically to maximum treatment depth, and the grout then injected as the pipe is slowly removed in lifts, creating a column of overlapping grout bulbs. The expansion of the grout bulbs displaces surrounding soils and the grouting increases the density, friction angle, and stiffness of surrounding granular soils.
You can increase effectiveness by sequencing the compaction grouting from primary to secondary to tertiary locations. In all soils, the high modulus grout column reinforce the treatment zone.
Advantages
Often more economic than conventional approaches such as removal and replacement, or piling. Can be done where access is difficult and in limited space.
Quality Assurance
APD can provide complete solutions which combine compaction grouting with real-time monitoring of affected structures, and has a variety of rig types to accommodate access constraints.

COMMON USES
- Suitable for rubble fills, poorly placed fills, loosened or collapsible soils, karst conditions, and liquefiable soils
- Often selected for treatment beneath existing structures because the columns do not require structural connection to the foundations
- Reduce liquefaction potential
- Decrease or correct settlement
- Increase bearing capacity
- Stabilize sinkholes or reduce sinkhole potential
