Underpinning

Helicon Foundation Underpinning for Deep Foundation Support

Foundation underpinning strengthens and stabilizes existing foundations by transferring the structural load to deeper, more stable soil or bedrock.

In Florida’s unpredictable soils, Helicon’s engineered underpinning systems offer peace of mind and long-term protection.

Micropile Installation

What is Underpinning?

Underpinning is the process of reinforcing an existing foundation by installing deep steel piers beneath the structure. These piers bypass weak, shifting soils and anchor into strong, load-bearing strata to support and potentially lift the building.

How Helicon’s Underpinning System Works

  • Brackets are mounted at strategic locations beneath the foundation
  • Steel piers are hydraulically driven into stable ground
  • The structure is gently lifted as piers reach the required depth
  • Brackets are secured; the system is concealed below ground level

Types of Underpinning

Not all foundations require the same solution. That’s why Helicon offers a range of engineered pier systems designed to address Florida’s diverse soil conditions and structural needs. Each type of underpinning pier serves a specific purpose, ensuring your property gets the most reliable and cost-effective stabilization possible.
Micropile Structural Support

Push Piers

Push piers are hydraulically driven steel piers that use the structure’s weight to push down into stable soil or bedrock. Once locked into place, push piers transfer the load away from weak surface soils and onto deep, reliable layers. This method is highly effective for stopping settlement and restoring the foundation to its original level with minimal disruption.

Helical Piers

Helical piers are advanced, screw-like steel shafts that are rotated deep into the soil. Their helical plates provide anchoring power, making them a preferred solution where soil conditions require added stability during installation or for light weight structures. Helical piers are especially effective in sandy or loose soils, offering immediate load-bearing capacity and long-term foundation security.

Slab Piers

Slab piers are designed to stabilize and lift concrete slab foundations suffering from settlement. By driving steel piers beneath the slab until reaching load-bearing stable strata, Helicon can restore support to sinking areas, reduce cracks, and prevent further movement. This solution is ideal for homes and commercial buildings with concrete slabs that have settled due to weak soils or fluctuating moisture.

Drilled-In Piers

Drilled-in piers (also called drilled shafts) involve creating a deep, reinforced concrete column below the structure. This system is ideal for heavy loads or when construction requires custom depth and diameter to handle complex site conditions. Drill piers provide powerful stabilization for large buildings and industrial structures that demand robust, long-lasting support.

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!!!

Advantages of Underpinning with Helicon

Foundation settlement isn’t just a cosmetic issue — it threatens the safety, stability, and value of your property. Helicon’s underpinning solutions go beyond quick fixes by addressing the root cause of foundation failure. Our deep steel piers provide lasting support, ensuring your home or business is secure for decades to come.

Micropile Structural Support

Stops foundation settlement and prevents structural damage

Helicon’s underpinning systems permanently transfer the weight of your structure onto solid, load-bearing soil or bedrock. By halting further settlement, the home or building is protected from ongoing damage such as sloping floors, foundation separation, and worsening cracks that can compromise long-term safety.

soil stabilization for foundation repairs

Closes cracks in walls and realigns misaligned doors/windows

Settlement often shows itself through visible cracks in drywall, brick, or stucco and through doors and windows that no longer open smoothly. Underpinning allows controlled lifting of the structure, helping close existing cracks and restoring proper alignment to doors and windows. This not only improves appearance but also increases energy efficiency and security.

Micropile Structural Support

Enhances structural integrity in hurricane-prone environments

Florida’s climate brings heavy rains, shifting water tables, and storm events that place additional stress on weakened foundations. By anchoring to stable soil layers, Helicon underpinning ensures your property has the resilience to withstand seasonal storms and hurricanes, protecting one of your largest investments.

More affordable than full foundation replacement

Replacing an entire foundation is disruptive and costly. Underpinning offers a cost-effective alternative that addresses the root cause of settlement without requiring complete demolition. Homeowners and business owners benefit from lower project costs, faster installation, and less disturbance to daily life.
