Compaction grouting is a specialized technique for in-situ densification of compactable soft or loose soils. A stiff grout is extruded into a soil mass to form an expanding bulb. Maintaining a controllable bulb of grout is the essence of this technique.
Any soil capable of being mechanically compacted can be densified by compaction grouting. The extent and the intensity of soil densification depends on the injection point configurations, the depth of the injections, the grout mix, and the amount of grout injected. Compaction grouting is effective in most man-made fill, organic soil, sand, silt, peat, and most clays.
The improvement of soil strength can be demonstrated by the Cone Penetration Testing Method before and after compaction.
On-site Footprint – small and compact
Mobility – our team can move easily between locations
Cleanliness – minimal waste and clean-up
Responsiveness – multiple crews means we are quick to respond
Compaction grouting is versatile: it lifts, levels, stabilizes, supports, fills, and densifies soil for new construction and existing structures, and it also reduces machinery vibration. Superior Grouting Services has completed hundreds of successful projects involving compaction grouting for:
Building Sites - Site improvement for structural support and prevention of soil liquefaction
Buildings & Structures - Settlement mitigation, foundation stabilization, controlled lifting
Machinery Pads - Controlled lifting and leveling, stabilization, vibration reduction
Tunneling - Surface settlement prevention, heading stabilization
Drilled Piers - Increased end bearing, lifting of settled piers, skin friction development
Pipelines - Lifting to grade without excavation, restoration of deformed pipes
Tiebacks - Anchor development
Hundreds of jobs have established that compaction grouting is an effective and economical method of compacting soils.
Compaction grouting can provide an answer to the problem of differential settlement of structures. The versatility of the technique makes it the method of choice for soil densification in areas where access to the site with heavy equipment is difficult or where noise is a problem. Grout injection points can be angled to reach areas under a foundation that otherwise could not be reached.
Compaction grouting can be used effectively for the controlled lifting of foundations, slabs, and other structures. Lifting takes place when the pressure at the bulb exceeds the weight of overburden, structures, and the shear strength of the soil cone above it. At that point, the soil shears, and the grout pressure lifts the soil and the structure built upon it.
By the careful use of this technique, entire structures can be lifted and leveled to precise specifications. Unlike other lifting or supporting techniques, compaction grouting supports structures and appurtenances on sound soil foundations.
Tunneling generally produces ground movements, which are manifested in the form of surface settlements or the loosening of adjacent soil and rock. Compaction grouting can be used for the prevention of surface settlement, for heading stabilization, and for remedial work in the adjacent soil.
Compaction grouting is accomplished by using a lean, thick grout mix of portland cement and silty sand. Natural sands with a range of 25 to 30% silts usually are used. The water content of the grout is adjusted to maintain a slump (ASTM C-143) of 1 to 1.5 in., with a maximum of 2 in.
Superior Grouting Services equipment, capable of achieving grouting pressures of up to 2000 psi, can be operated at distances several hundred feet from the injection site. Superior Grouting’s drilling equipment provides the capabilities of drilling in low overhead tight access work areas.
Superior Grouting Services has extensive experience in all types of pressure grouting for site development, new construction, and the stabilization of existing structures, ranging from large diameter product storage tanks and multi-story buildings to individual homes and buildings of all types. We work closely with owners, engineering firms, contractors, and public agencies throughout the Gulf Coast.

“We have worked with Ron since 1997 helping him grow his business. Superior is a company that you know is going to be successful for the long haul. Their attention to customer service, quality of workmanship and their ability to find creative solutions to see that the job is done right the first time is what makes them a great company!"
“Thank you for a job well done, The attention to detail by Andy and Octavio is praise worthy. Companies build their name based on the quality of their people this is evident. The product performed as indicated, or better than expected, look forward to years of good performance and remaining leveled. To the entire staff, thank you for a job very well done”
“Superior Grouting used injectable foam to fix my cracked concrete. At the same time they lifted various parts of the concrete to even out the surfaces. They were FANTASTIC. On-time, hard-working, clean, precise – everything you want in a contractor. Their pricing was more than fair and their work speaks for itself. I highly recommend anyone using injectable foam for foundations, or lifting any kind of uneven surface to call Ron or Erica at Superior.”
“Great work performed by Andy and Octavio, they stuck around until the work was done it was almost 2200 as they wrapped things up. Professional, courteous and a great attention to detail, most companies build a great name based on the quality of their people and these guys demonstrated it. The product worked amazingly well during installation, it was a dramatic improvement with almost no damage. I am looking forward to seeing how well it will perform in years to come."
