Everything that you need to know about Screw Pile Installation

screw pile installation

A screw pile is a long, vertical pole used to strengthen the ground under a building or other structure. When it comes for screw pile installation, they’re typically made of steel or timber and installed into the ground with an auger (a drill bit on a long shaft), which provides stability for foundations and retaining walls. There are several different types of screw piles, each suited to different applications:

  • What is a screw pile?

A screw pile is a steel bar with a helical thread. It is driven into the ground by a pile driver, creating friction against the soil and holding it in place.

The most common form of screw piles is concrete filled; these serve as both anchors and footings for structures such as buildings or bridges (see image). The concrete fill prevents corrosion of the steel bars within the ground while also increasing strength in compression.

In addition to providing structural support through tension forces provided by helical threads, screw pile installation also provide stability through resistance against bending moments generated by lateral loads on buildings or other structures.

  • How is a screw pile used?

Screw piles are used to support buildings, bridges and other structures by being embedded into the ground. They can be installed in areas of poor soil conditions such as clay or sand where traditional foundation methods are impractical. The screw pile is drilled into the ground and then driven deeper until it reaches a solid bearing layer beneath the surface of the soil. This process is repeated as many times as necessary for your project needs.

  • Where can you use a screw pile?

Screw piles can be used in any situation where you need to support, secure, anchor or ground a structure. That includes situations where the ground is soft (like soil) and situations where it’s hard (like rock).

It also includes situations where there isn’t much room for the screw pile to penetrate into the ground (like tight spaces) and situations where there is plenty of room for it to penetrate into the ground (like open areas).

You might be wondering how exactly these things work. Screw piles are basically long screws that have been bent into a cylinder shape.

They are inserted into the ground with a special machine called an auger until they reach what engineers call “load bearing capacity”, – which just means deep enough that their weight isn’t going to cause them to bend or snap under pressure from whatever you’re trying to anchor them against!

  • What type of screw piles are there?

There are many different types of screw piles. The most common and versatile is the driven screw pile, which can be used for temporary or permanent structures. Driven screw pile installation using a powered auger and driven into soil or sand with a hammer action.

They offer high load capacities to resist uplift forces from wind loads, seismic activity, and other extreme conditions. These piles have been used throughout history for various purposes, including bridges, buildings, docks and piers — even ships!


Screw piles are a great alternative to traditional foundations and are used in many industries. If you’re looking for a way to build without digging deep holes in the ground, then this may be the option for you!
