Everything you need to know about screw piles
The screw pile, or helical anchor, is a type of foundation that can be used to support structures such as homes and buildings. The screws are driven into the ground by hand, drill or mini excavator. They may also be installed using a special machine called a helical pile driver.
- The screw pile was invented by Alexander Mitchell in 1836.
Alexander Mitchell was a Scottish civil engineer who invented the screw pile in 1836. The idea behind Mitchell’s creation was to improve upon earlier piling technology, which could only go down as far as water tables would allow (about 20 feet). He wanted to create a new type of piling that could be driven through these shallow layers and into better soil below them. This way, engineers could sink a foundation deeper than ever before—and thus support structures like bridges and buildings that were built on sturdier foundations.
The first patent for this invention, called “The Improved Screw Pile,” was issued by England’s Patent Office in March 1837; it detailed how one person could operate both ends of the machine using levers and gears instead of cranking handles manually, making it easier for workers to drive piles into the ground at great speed without getting exhausted from overworking themselves like they did with traditional methods. Within five years after this patent was granted there were more than 100 machines being used all around Britain; many other countries later followed suit when they saw how effective these tools had been at building infrastructure projects quickly and efficiently within their borders too!
They are also known as helical anchors, piers and piles.

- Screw piles can be installed by hand or with a mini excavator.
You can install a screw pile by hand or use a mini excavator. If you are installing a small number of screw piles, it is easier to use a hand-operated drill rig. With the drilling equipment, you can install the pilings by drilling a hole and inserting each piling individually. However, for larger projects, it may be more cost effective and efficient to use an excavator equipped with specific pilings:
The mini excavator will drive screws into the ground with less effort than required when using manual labor alone. This means that your work can progress faster when using this method!
Screw piles are used for foundations for decks, sheds and homes, as a support for wind turbines and as an anchoring system for shoreline protection.

Screw piles can be driven into the ground by hand or with a hammer drill (or both). To install with an impact driver, you’ll need your screw pile and driver bit (as well as oil if it’s not self-lubricating), plus some form of wrench or socket tool. Screwing in screw piles is easy enough that even kids can do it—but don’t let them unless you want to take all the credit when their project is done!
Screw piles can be installed into ground composed of gravel, clay, silt, sand and very dense soils like till.
Screw piles are an excellent choice for many types of soil, including:
- Loose and dense soil
- Wet or dry soil
- Sandy soil
- Typical screw piles are made from steel hollow tubes. Some are made from solid steel and some have helical blades attached to them.
Typical screw piles are made from steel hollow tubes. Some are made from solid steel and some have helical blades attached to them. The helical blade or the spiral is designed to cut into the soil as it is driven into the ground by a driver or hammer drill, creating a hole behind it in which dirt is displaced. This helps keep the depth of penetration constant, eliminating any need for additional excavation equipment such as wedges or torque wrenches.
Screw piles are available in many different sizes, shapes and capacities that can be adapted to suit almost any job site and soil conditions!
- The smaller the screw pile’s diameter is, the more difficult they become to install in some soils.
The smaller the screw pile’s diameter is, the more difficult they become to install in some soils. This is because smaller diameter piles are less stable than larger diameter piles. In order for them to be installed properly, you need to find a good soil that will allow your screw pile to be secure enough for it to work effectively as a support structure. If you’re not sure what kind of soil you have on your property, ask an expert or do some research online so that you can determine whether or not it will be suitable for installing into your ground!
- Piles with helical blades are preferred over smooth-shafted piles in loose materials such as sand, silt and organics.
In loose soils, piles with helical blades are preferred over smooth-shafted piles. Helical blades allow the pile to penetrate more efficiently and resist lateral loads better than smooth-shafted piles do. Also, because they are stronger than smooth-shafted piles, they can be used in deeper foundations (although this will vary by manufacturer).
As you can see, screw piles/helical anchors/piles are a great option for many projects. They are easy to install and can be used in a variety of soils. The biggest advantage of these types of foundation systems is that they do not require any excavation work, which means there is no disruption to your yard or garden during installation. With so many different sizes, shapes and capacities available today, we hope that this article has helped answer some questions about what screw piles are all about!
