WHAT IS IT?

Helical piles are square or round shaft galvanized steel piles that screw into the ground. They are incorporated into other foundation elements like footings, pile caps or structural slabs and can provide load and/or uplift capacities up to 100 tons or more per pile. They are approved by national building code agencies BOCA, ICBO, SBCCI, CCMC and ICC, the CHANCE® helical pier and tension anchor has become the deep foundation system of choice for architects, builders, contractors, engineers and geotechnical firms.

WHY YOU NEED IT

Helical piles provide excellent and affordable foundation solutions for both residential and commercial projects where problematic soil conditions exist or where there is limited access to the site. Advantages of using helical piles over other piling systems are:
  • Fast installation
  • No vibration during installation
  • Can eliminate grade beams at pile cap locations
  • Ease of installation in limited access areas (where cranes cannot be mobilized)
  • Minimum disturbance to site
  • No excavation is required
  • All galvanized steel foundation
  • Immediate structure installation
  • All weather installation
  • On-site load test capability
  • 30 year transferrable materials warranty

METHODOLOGY & INSTALLATION

Each pile is designed by our engineers to perform based on the required loads and soil conditions for your project. Helical piles are quickly installed either with a mini-excavator or, in limited space applications, can be installed with a hand-held device. 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.

A plan is created indicating the locations of the piles, capacities and technical specifications (shop drawings).

The plans are submitted to the local building department for permit or to the contractor of record.

IMPLEMENTATION

We mobilize onto your site and review the scope of work with you. The mason excavates for his footings, our crew follows directly behind the mason and starts installing the piles. The piles are cut to the desired length and typically, have a steel pile cap installed. The mason then follows directly behind our crew and places the forms and reinforcement steel.

TESTING

If requested, the piles can be tested for compliance of both compression and tension capacities. The engineer of record determines the needed capacities and the piles are typically tested to a safety factor of x 2. The testing is completed by Foundation Technologies and reviewed by the engineer of record.

FINALIZATION

Installation logs are kept for each pile and reviewed by the engineer of record. The logs keep track of the total depth achieved of the pile and pressures encountered during installation. The logs are submitted to the building department along with a Certificate of Completion from the engineer to certify that our installation was in compliance with the plan.
