Screw pile foundations
A screw pile may have more than one helix (also called a screw), depending on the usage and the ground conditions. Generally, more helices are specified if a higher load is required or softer ground in encountered.
 Screw pile foundation installation
Installing screw pile foundations takes considerably less time and machinery and usually costs less than installing a standard concrete foundation. Depending on the size of the piles, a range of different size of plant can be used for the installation, including hand-held machines. In many instances, only one machine is required for a steel, screw pile foundation installation. Screwed piling is installed with a hydraulic torque drive.
 Screw pile usage
Screw pile foundations are the preferred choice for a number of industries. While they were originally developed for the nautical industry, they are now used in rail, road, telecommunications, and civil engineering. Screw piles can bear large tensile and compression loads, so they are often used for masts, signs, and retaining structures.
 Screw pile benefits
Benefits can include:
- Ease of installation (using fewer machines and taking less time).
- Faster installation.
- Lower carbon footprint.
- No need to remove soil from the site.
- Ability to install in close proximity to existing structures.
- Ease of removal when no longer needed.
