Underpinning & Foundation Repair

WHAT IS IT?

Helical and Resistance piles are galvanized steel piles that are attached to a building’s foundation, installed at intervals around the perimeter at the affected locations and screwed or driven down to competent soils to bypass the problematic soils causing movement to the existing structure.

WHY YOU NEED IT

Helical and Resistance piles are typically the best solution to either stabilize or lift a residential or commercial structure. They are also used to retrofit a foundation to increase load requirements (e.g., to add a 2nd story addition) or to provide uplift resistance to hurricane force winds. Florida soil conditions may cause structures to move upward or downward due to poor or loose soil conditions, shrink and swell clays and decomposing organics (that big tree you cut down ten years ago that was next to the house and now the decomposing root system is allowing the soils above to compress and your foundation to settle).

METHODOLOGY & INSTALLATION

Each pile is designed by our engineers to perform based on the required loads and soil conditions for your project. The process starts with gathering data about your existing soil and structure’s condition.

TESTING & DESIGN

For most projects, the design process occurs with gathering information about your project.

We obtain soils information from a geotechnical engineer to define the soil conditions.

A structural engineer works with us to define the necessary capacity of the piles, the pile type and configuration based on the soils report and existing structural conditions.

The pier type is determined: Helical Piers, Resistance Piers & Pull-down Piles (grouted pile used to combat buckling).

A plan is created to resolve the settled condition of the structure and a permit is applied for.

IMPLEMENTATION

We mobilize to your site and review the scope of work with you. The workmen are careful to protect the surroundings and clean up as work proceeds. The installation of the piles is documented and variances are discussed immediately with the engineer of record, as needed. At the end of the project, we review the site conditions with you to ensure the site is being left as planned.

If needed, we also offer full-service cosmetic repairs to our clientele.

FINALIZATION

The installation logs are recorded for each pile and reviewed by the engineer of record. These logs track the total depth achieved of the piles and pressures encountered during installation. The logs are submitted to the local building department along with a Certificate of Completion from the engineer to certify that our installation was in compliance with the plan. The installation ends at this point, the permit is finalized and you can rest assured that you have a strong foundation which you can rely on and give you peace of mind for many years.

HOW THEY ARE USED

Resistance pile – round shaft columns that resist with superior strength that resist buckling and can be installed in hard-to- access areas.

Helical pile – fast, efficient and affordably installed; the best solution for most applications.

Slab pile – support for existing interior and exterior slabs and walkways.

Grouted pull-down pile – is a helical anchor with a grouted shaft used to strengthen the pile from buckling due to very loose soil conditions.

BENEFITS

Underpinning a settling structure allows one to retain or recapture an asset’s value through repair and remediation. Where a structure is thought to have lost its value due to settlement, it may now be salvaged. The asset value returns to a marketable condition and cash flows of a real estate investment can resume or be created. The cost of repair with an underpinning solution is almost always more economical than removing the structure, repairing the soils and rebuilding.

All underpinning materials are covered with a transferable 30 year material warranty.
