Helical piles are a permanent foundation solution, and they ensure a strong and fast foundation for use on a variety of government projects. They are a patented, trusted, permanent solution in this industry. The patented PierTech system and the new construction bracket allow for quick and easy installation. Without the need for concrete, there are no delays due to weather or wait times for curing. This application has the use for both round, used for compression, and square shaft, used for tension, material.
Why use PierTech's patented system?
| Product | Product Description | Application Description |
|---|---|---|
| Helical Lead Section | Pipe section with one or more welded helical bearing plates | Typical lead section 2-7/8" OD, 5' to 7' long pipe, with a single Helix and Cross-Lock coupling. |
| Helical Extension Sections | Pipe section with Cross-Lock Couplings welded to each side | Typically requires 1 to 2 - 2-7/8" 5' or 7' long Extensions for an overall length of 14' to 21' depth. Attaches to lead section with Cross-Lock Connection. |
| Square Shaft Helical Anchor | Square bar with one or more welded helical bearing plates | Typical square shaft anchor section 1-1/2" square bar in 5ft or 7ft long square bar, with a double or triple helix. |
| Insta-Brace Bracket | High-strength steel bracket that attaches to the square shaft helical anchor | Steel bracket attaches to the top of the 1-1/2" square shaft helical anchor using the required nuts and bolts which attach it to the connector. |
| New Construction Bracket | Steel Plate welded to a Cross-Lock Coupling or Coupling for the Hercules Pile System | Steel bracket attaches to the top of the 1-1/2" square shaft helical anchor using the required nuts and bolts which attach it to the connector. |
| Helical Equipment Package | Hydraulic rotary motor and gearbox attached to a power source used to install the pile into the ground | The helical equipment package will normally be mounted to a skid skid steer or excavator, and the standard installation drive heads will range from 6,000 ft-lbs to 16,000 ft-lbs. A digital or analog torque monitor will be used to calculate the pile's capacity. |
