Overview

What Are Helical Piles?

Helical piles, also called screw piles, are engineered steel foundation systems designed to transfer structural loads into stable soil below the surface.

Each pile consists of a steel shaft with one or more helical plates that are mechanically rotated into the ground using specialized equipment until the required depth and torque are achieved.

Expanded infographic explaining how helical piles work

Steel Shaft

The central structural component that supports and transfers loads.

Helical Plates

Circular steel helices that allow the pile to screw into the ground.

Load Transfer

Structural loads transfer into stable soil at deeper bearing layers.

Installation Process

How Helical Pile Installation Works

1

Site Evaluation

Soil conditions, access, structural loads, and project requirements are reviewed before installation begins.

2

Pile Positioning

Piles are precisely positioned according to engineered layout requirements.

3

Mechanical Installation

Specialized hydraulic equipment rotates the pile into the ground with minimal excavation.

4

Torque Verification

Installation torque helps verify load-bearing performance and foundation stability.

5

Foundation Attachment

Brackets or structural connections are installed to support the finished structure.

Engineered Performance

How Helical Piles Support Structural Loads

Helical piles transfer structural loads into deeper, stable bearing soil below weaker surface layers.

Proper installation depth, soil conditions, torque values, and pile design all contribute to long-term structural stability.

Compression Loads Vertical structural weight support
Tension Loads Resistance against uplift forces
Lateral Loads Resistance against side movement
Soil Conditions

Built for Challenging Ground Conditions

Clay Soil

Common throughout Southern Ontario and often affected by seasonal movement.

Wet Areas

Helical piles can help reduce excavation challenges in wet conditions.

Freeze-Thaw Conditions

Installed below frost depth for stable support through seasonal changes.

Sloped Properties

Useful for challenging grades and uneven terrain.

Applications

FAQs

How Helical Piles Work FAQs

How deep do helical piles go?

Installation depth depends on soil conditions and structural load requirements.

Can helical piles be installed in winter?

Yes. Helical piles are commonly installed year-round in Ontario conditions.

Do helical piles rust?

Helical piles are manufactured with protective coatings and engineered for long-term performance.

Are helical piles permanent?

Yes. Helical piles are designed as permanent structural foundation systems.
