Compaction Grouting for Sinkhole Repair & Soil Stabilization

Compaction grouting is a proven method for repairing sinkholes and stabilizing loose or weak soils beneath Florida structures. By injecting a thick grout mixture under high pressure, voids are filled, soil particles are compacted, and the limestone surface is sealed — creating a dense, stable foundation layer.

For homes, businesses, and pre-construction projects, Helicon’s compaction grouting provides permanent protection against sinkholes and settlement.

What Is Compaction Grouting?

Compaction grouting is a soil improvement and sinkhole repair method that works by injecting a dense grout mixture into the ground. Unlike chemical grouts or foams that permeate soil, compaction grout pushes directly into loose soils, filling voids and compressing surrounding material to restore strength.

This process not only fills dangerous underground cavities but also creates a hardened grout mass that caps and seals the limestone surface, preventing water infiltration that often leads to further sinkhole activity.

How Helicon’s Compaction Grouting System Works

Injection pipes are drilled at precise angles using specialized compact drilling equipment
A dense grout mixture is injected under high pressure into voids and loose soils
Grout displaces and compacts soil, strengthening weak zones and sealing cavities in the limestone
Structural movement and injection pressures are carefully monitored during the process
Upon completion, all injection pipes are raised and removed, leaving a dense, stable foundation

Great service. Efficient timeline. Very fair pricing for the big job in my situation (pool on the side of a massive cliff/hill stabilization and lift).

Bryce and his team were on time explained the process and they were very professional.
Completed the repairs as quoted and clean up the work site.
I am very pleased with their work and professionalism.

The assessment and process easy. Price was reasonable compared to others and the workmanship was excellent. They listen to what I had to say based on my experience doing this 15 years ago. I like that they had a five year warranty and hoping everything goes well with the lifting of the cement next to my pool area.

Helicon is definitely the company to call when you have foundation issues. The process was explained in detail and best of all in Layman’s terms. We were shown the progression and what the lift was doing to correct our issues.
Our final walk through was explained from room to room, and they notified us when they were finished and were leaving. I was especially impressed with them cleaning so well after completing everything. Thank you so much Helicon for doing such an amazing job!!!! Douglas, Tony, John, Joshua, and Raul.
THANK YOU

I had a screen porch blow off during Hurricane Milton. One of the rebuilding efforts was to ensure the foundation under the wall that had supported the screen porch's attachment was secure. Helicon came and pumped in an expanding grout under the wall in question. Great job was done with precision measurements, and the area was left clean and neat. Well Done!

Successful job, polite and professional workers, nice job, appreciate cleaning up and fast and efficient project.

I had an excellent experience with Helicon Foundation Repair. From start to finish, their team was professional, knowledgeable, and transparent about every step of the process. David took the time to explain my options clearly and delivered exactly what they promised — on time and within budget. The crew Rey, Brent and Ajay worked efficiently and kept the area clean throughout the project. It’s clear they take pride in their workmanship and customer service. I highly recommend Helicon Foundation Repair to anyone in need of reliable and high-quality foundation services.

They stabilized the driveway which was about to collapse. Professional and courteous service.

Jan and his team did an excellent job at our home yesterday. Our project had challenges and Jan kept up apprised and worked with us to make a decision for each section as needed. That communication led to an end result was as we expected.

My driveway had a sudden hole appear that was about 3' deep. No water appeared to be the cause, it just dropped. Helicon came out stabilized the driveway and leveled it. They have the skilled workers and the right equipment to make this look easy. I am confident that I will not have any more issues with my driveway!
