What is Compaction Grouting?

Compaction grouting is a ground-engineering technique in which a cement-like substance is injected into the ground to reinforce soil structures and fill subsurface voids. In this process, holes are first drilled in the ground and then an injection pipe is inserted all the way down to a solid substrate. Next, the grout mixture is pumped into the ground as the pipe is slowly removed. This technique creates a series of overlapping grout bulbs which expand to reinforce the surrounding soil structures. Compaction grouting is most commonly used to fill sinkholes or to level sinking foundations.

While the basic principle of the compaction grouting process has been around since at least the 1950s, nowadays, ground engineers use computerized technology such as compaction grouting meters to monitor various data such as depth, pressure, flow, injected volume, and other site-specific information. Such advances in technology provide ground engineers with a better idea of how deep they are drilling, how much grout they are injecting, and how this grout is being distributed throughout subsurface voids. Not only can this help ground engineering companies provide a more accurate and consistent level of service, but it also allows them to keep detailed records of past projects and gives them a better understanding of how ground conditions in a specific area may have changed over time.
