Find quick answers to common questions about ECP helical pile systems.

A helical pile is a steel deep foundation system with one or more helix-shaped plates that are mechanically advanced into the soil to transfer structural loads to suitable bearing soils.

Helical pile capacity is determined using engineering requirements, soil conditions, pile configuration, and installation torque. Installation torque can be used to help verify the pile has achieved the required capacity.

The appropriate shaft depends on the application, required load capacity, soil conditions, installation requirements, and project specifications. ECP offers multiple round shaft, RCSB, and square tube options for different foundation needs.

Installation depth varies by project and soil conditions. Helical piles are advanced until the required depth, suitable bearing soil, and/or specified installation torque is achieved.

Helical piles can be used in a wide range of soil conditions, but the appropriate shaft and helix configuration depend on the site’s specific soil profile and engineering requirements.

Helical piles are typically installed using hydraulic rotary equipment capable of applying and monitoring the torque required by the project specifications.

Yes. Helical piles can be used to support new construction as well as underpin and stabilize existing foundations, depending on the project requirements.

The cost of a helical pile installation varies based on the number and type of piles required, installation depth, soil conditions, required capacity, site access, and project-specific engineering requirements.
