Soil Stabilization

Unstable soil is one of the leading causes of structural issues in Florida homes and properties. Whether you’re seeing cracks in your foundation, sinking slabs, or voids opening behind seawalls, Helicon’s soil stabilization solutions restore ground strength and protect your investment-without major excavation.

Warning Signs Your Soil May Be Failing

Soil instability often develops gradually-but once it starts, damage can accelerate quickly. Look for these warning signs:

Underpin Foundations

Cracked or Shifting Foundation

Fractures in walls or uneven floors often point to soil movement beneath your home’s foundation.

uneven concrete slab

Sunken or Uneven Concrete Slabs

Driveways, patios, or pool decks that dip, tilt, or crack can signal erosion or voids below the surface.

voids or depressions in the yard

Voids or Depressions in the Yard

Unexpected low spots or soft ground may indicate soil washout or decomposing organic material underground.

cracked or leaning wall

Leaning Seawalls or Retaining Walls

Soil movement behind vertical structures can push walls outward, leading to tilting or collapse.

detached patio or pool deck

Detached Patios or Pool Decks

Separation from the home’s structure is often due to shifting or settling soil beneath the slab.

Underpin Foundations

Persistent Water Pooling

Standing water after rain may be a result of poor soil compaction and drainage-common precursors to erosion.

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!
Rayton, Jay, Luis, Danny did a great job and left the house looking untouched. Very communicative through the installation process.
Excellent work, fast, efficient and at an affordable price. Thanks
From start to finish Helicon was patient, professional and understanding with Condo association slow deliberations. They finally months later received the approval. All the way Helicon executed a clean and neat install of remediation to soil and unstable earth around the condo. Great crew and good job. Tom
Helicon stabilized the soil behind our seawall earlier this spring. After a very wet summer, there was some new subsidence in three places along the seawall. They promptly returned, honoring their warranty, and inject additional material to reinforce the few spots that needed attention. Excellent customer 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.
The sales representative, Douglas, reviewed my home carefully, asked questions then prepared a drawing and contract. He was detailed in information and provided easily understood answers to questions. There was no pressure.

Follow up with associates was made in a timely manner by text, voice mail, and email. Tony easily answered my questions.

The techs arrived on time as scheduled. Professional, polite, focused on their tasks, respectful of neighbors and my home, treated the installation as if it were in their home.

Highly recommend Helicon!
Isaiah , Alfonzo, shelumiel, Antonio were absolutely outstanding! These guys take the job to another level! They went down till they hit rock! Totally relentless work ethic on this crew! Can recommend these guys a thousand times over - you will get only the best from this crew. Also, they were super polite and considerate! We highly recommend them and will always be grateful for the amazing experience with Helicon!!!
We are a Water Managment Special District in the state of Florida and when we started looking into repairing our outflow Dam that is responsible for 16 lakes, we took multiple bids and ended up choosing Helicon. It was a great choice! They were able to walk us through the steps of how they would be able to properly seal and help strengthen this outflow Dam that is essential to our community. Using their specialty hydrophilic foam, they were able to inject into our Dam sealing cracks and empty spaces that had eroded over time as well as pushing out water that had seeped in. they were able to accomplish this large undertaking within a day and they were able to instill a confidence in the structure that had not been there for decades. Not only would I recommend them to other government entities, companies, or individuals we are looking to work with them again in the future on the possibility of some different types of projects.
I contacted Helicon when I notice my garage floor was sinking next to the house. They responded by looking at my floor and said that chemical grout would lift and stabilize it. The crew that came to do the repair did a fantastic job!!! I would recommend this company!!!

How Helicon Stabilizes Your Soil

Our advanced polyurethane injection methods are designed to permanently stabilize Florida’s most problematic soils. Each approach is fast, clean, and tailored to your specific needs.

permeation grout

Permeation Grouting

We inject low-viscosity polyurethane deep into loose soil. As it expands, it binds soil particles into a dense, unified layer-strengthening the ground while preventing future washout.

compaction grouting

Compaction Grouting

In areas with large voids or weak zones, we inject high-expansion foam to displace soft soils and compact the surrounding material. This reinforces support under foundations, slabs, or seawalls.

Where Soil Stabilization Makes a Difference:

Home Foundations

Prevent structural damage and settlement.

Driveways, Patios & Pool Decks

Restore level surfaces and eliminate tripping hazards.

Seawalls & Retaining Walls

Stabilize high-pressure zones to prevent shifting or collapse.

Commercial Projects

Support buildings, roads, or infrastructure with unstable subgrade.

What Causes Unstable Soil in Florida?

Florida’s environment presents unique soil challenges-especially near the coast, in high water table zones, or areas with sandy or organic fill. Here’s what leads to instability:

Property Construction & Development Organic Matter Decomposition
High water tables Karst Topography
Ground & Soil Erosion Soil Composition Variability
