Compaction grouting is a type of pressure grouting that becomes more dense and compacts soil that is in need of stabilization.
For foundation repair it is most effective in stabilizing non point load bearing structures such as swimming pools or flat pads and pavements (interior floor pad). It can be performed either top down or bottom up.
Most flat structures settle because of soil being too heavy to support itself. Ten feet of soil on top of a weak layer can cause it to compress. The surface then follows the rest of the soil causing distress in the pool, pavement or any structure located above the problem. To correct the issue the soil stabilization is needed.

1. First, the injection casing is driven to the proper depth. This can be done in one of several ways. The simplest is to hammer down the casing with an air powered driver or a hydraulic powered hammer. Sometimes pre-drilling is required when penetration through harder soils is required to reach unconsolidated soils. Usually with a down in the hole hammer. This is a common step that is often not followed with vigilance.
2. Once the proper depth has been reached. Grout is then pumped down and injected. For compaction grouting (pressure grouting), a very stiff mix with in internal high friction is used. For true compaction grouting, a 2” diameter or larger casing is required. Any casing less than 2” is not true compaction grouting. Grout pressure and volume should not be large enough to fracture the soil.
3. Once a volume, pressure or ground movement marker has been met, the casing is raised 12 to 24 inches and the same grouting process is repeated.
4. This grouting and lifting procedure is repeated until the surface is reached. The finished work results in successful soil stabilization.
