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.

Get engineered plans from a licensed, 3rd party engineer to see exactly what you need.


Know exactly what type of support you will need for the foundation supporting your structure.


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.


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.

Jet grouting machine


  • 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


Compaction grouting can improve soft and compactable soils, stabilize or re-level existing structures, stabilize existing underground structures such as pipes and tunnels, reduce water seepage and mitigate settlement.

I had APD stabilize the foundation on my old bungalow in seminole heights, and they did a great job. very careful, responsive and all done at a good price. they even lowered the price, after the job was completed, because they used less material than they quoted me for.Danny the sales manager was awesome, and experienced in the field. the crew that came out to do the work were respectful, skilled and professional.Lisa in the office was super helpful when i messed up some of the scheduling and got things back on track.all around good company doing good work.

We had ADP take care of our foundation issues for a home we recently purchased. They are fair priced compared to their competitors. On time and were there for two days, cleaned up after themselves and very polite. We were pleased with their services and the work is guaranteed..

I can't say enough for the professionalism and work of APD on this project. Our 1925 bungalow was built low to the ground, with the joists just 6" from the ground. APD's folks had to go in by cutting a hole in our hallway floor and digging a channel the length of the house to allow them to squirm under each joist in putting in new supports and running a steel beam under much of the house. They did a beautiful job, never complained once about the very difficult and dirty work (they had to move the dirt from the ditch at least four times because there was really no where to put it out of the way of the repairs as they moved under the house). The company over all was in touch weekly leading up to the work to let us know it was still on schedule, etc. And they completed it in two days. All in all, the most professional company I've worked with over many years of major home improvements.
