Compaction Grouting is the process of injecting grout into a soil to improve bearing capacity.  A low slump grout is injected under high pressure to expand bulbs in a controlled system through an injection pipe.   The injected grout pushes the soil to the side as it forms a column or bulb.   Compaction Grouting is often utilized where there is limited access for retrofit applications.
