Product Description
Helical Ground Anchors & Earth Screw Piles
Helical piers, also known as anchors, piles or screw piles, are deep foundation solutions used to secure new or repair existing foundations. This modern improvement to traditional cement footings features engineered steel posts with screw-like helices for superior performance.
Product Overview
Each helical pile consists of extendable base equipment made with helical engineered metallic plates attached to a central steel shaft using round or rectangular cross-sections. The steel plate thickness, diameter, number, and helix configuration are determined by design requirements, environmental conditions, and geotechnical parameters.
Key Advantages
- Time-proven, versatile, and technically sound system
- Lower cost and faster installation than traditional methods
- Installs quickly with small or handheld equipment
- Can be installed in limited-access areas or tight spaces
- Site cleanliness with minimal damage to landscape
- Soil load bearing capacity tested during installation
- Available with single, double and triple helix blades

Applications
- Solar energy system foundations
- Timber-frame construction
- Advertising and traffic systems
- Urban garden and landscape construction
- Flag poles and signage
- Foundation repair and stabilization
- Lighthouses, roads, railroads, and telecommunications
Installation Process
Screw piles are wound into the ground using various earthmoving equipment fitted with rotary hydraulic attachments. Machinery ranges from skid-steer loaders to 80 tonne excavators with torque capacities from 5,000 Nm to 500,000 Nm.
The lead section with multiple helical blades is first rotated into the ground, followed by extension sections as needed. The top of the pile is incorporated into the foundation system via brackets or connection methods.
