The technique of High Energy Impact Compaction (or Impact Roller Compaction) involves application of high energy impulsed at the ground surface utilizing rollers.

Rapid Impact Compaction is a ground improvement technique that densifies the soil by pounding it at high frequency with a medium sized pounder.

Slurry Wall is a ground improvement technique that uses non-structural underground barriers to build cut-off walls to prevent the flow of water.

Dynamic replacement is a ground improvement technique that reinforces fine grained soils with a network of dynamically pounded pillars.

Vibrocompaction is a ground improvement technique that densifies the soil by shaking it with a vibro probe.

Bi-modulus columns is a ground improvement technique that reinforces the soil by a combination of CMC and stone columns.

Soil Mixing is a ground improvement technique that reinforces the soil by mixing in situ a network of grout and soil columns.

Dynamic compaction is a ground improvement technique that densifies the soil by repeatly pounding it with a high energy pounder.
