Poly-Lift Helical Piles and Piers

Push Piering

What are Helical Screw Piles?

Helical piles are one of the foundation lifting options we provide. It is a form of deep foundation systems that have been used since the early 1900s in waterfront foundations. They are highly suitable for fractured footings, light loads, temporary applications, and high groundwater conditions.

What do they do?

The purpose of helical piling is to provide foundation support for structures of all types and sizes. Helical piles are embedded deep underground in order to disperse the enormous weight which sits atop them. Multiple piles are installed to create a platform, on which your home or building can rest.

Parts of a Helical Pile

There are three parts of a helical pile, the Lead Section, Extensions, and Termination.

  • Lead Section

    The lead section refers to the first helical pile section to be installed. This is responsible for penetrating the soil and displacing the load from the foundation into the ground through helical bearing plates or helices.

  • Extensions

    Extensions of a helical pile consist of a shaft with a coupler on each end, male and female. The first extension is bolted to the lead section and additional extensions are bolted on until the helical pile reaches the desired torque and depth.

  • Terminations

    Terminations connect the helical pile to your foundation that it is supporting. We use 6 bolts to attach our frame to your foundation, ensuring a secure fit.

Advantages

It can be used for a wide variety of soil conditions
Year round installation in any weather
Rapid and easy installation
Ablilty to be removed and reused
Immediate load carrying capacity
Low carbon footprint – sustainable technology

Limitations

More space is needed than pier pushing
Doesn’t work well in gravel, rock, and cobble deposits.

To Install a Helical Pile, We:

  • Expose Foundation
    Expose the Foundation
  • Prepare Footing
    Prepare the Footing
  • Insert Helical Pipe
    Insert the Helical Pile at a 30 Degree Angle and Set Into the Ground
  • Place Pipe Parallel
    Place Pipe Parallel to the House and Push Down Into the Ground.
  • Additional Fitting
    Bolt Additional Extension to the Helical Pipe, to Push Pile Further Into the Soil.
  • Drill Helical Pipe
    Drill Helical Pile Deeper Into the Soil.
  • Repeat Until Reach Desire Depth
    Continue to Add Extensions and Drive the Pile Into the Soil Until the Desired Depth Is Reached.
  • Attach Foundation Bracket
    Set the Foundation Bracket Into Place
  • Fasten Found Bracket
    Secure Foundation Bracket With Six Bolts and Set Pump Frame Onto the Helical Pipe.
  • Attach Hoses & Pump
    Use Hydraulics to Pressurize the Piles to Ensure a Good Lift.
  • remove hoses & fasten pipe
    When Foundation Is Lifted, Remove the Hydraulics and Fasten Pipe to Foundation Bracket With Two Bolts.
  • Remove Pump Frame & Drill Hole
    Remove Pump Frame and Drill Hole Into Pipe.
  • Attach Bolt & Cut Pipe
    Fasten Bolt to Hole and Slice the Helical Pipe to Be Flush With Foundation.
  • Foundation repair is complete
    Foundation Repair Is Complete.

Frequently Asked Questions

No, Helical piers need to be installed by a certified installer, and often times require engineering.

They are permenant, and will last the lifetime of the structure

Depending on size and weight of a structure, an engineer or helical manufacturer will determine the exact amount needed.

They are driven to a depth specified by engineers, can be between 20' and 60' deep depending on use.

Helical piers can be installed fairly quickly, depending on depth.
