Screw Piling from Helcon: What Makes Screw Piling Versatile?

January 9, 2023

Buildings can only last for a long time if they are built on top of a solid, reliable foundation. Deep building foundations conveniently ensure that the above properties will not be disturbed by any ground movements. They also help in distributing the weight of the properties, making sure that overloading will be avoided entirely.

Many processes can be done to generate building foundations. But one popular process that can provide great foundations to buildings is screw piling.

Screw piling is the use of screw piles or helical piles in building and constructing deep property foundations. Screw piles are often made from circular hollow steel sections on which helices are attached. They are then cut into the ground at a constant pitch until they reach the target depth. Upon filling them with concrete, the protruding reinforcing is then connected to the building above, ensuring that the property will remain intact for decades.

General Advantages of Screw Piling

Tons of advantages are associated with screw piling. Some of them are as follows.

• Easy Installation: One advantage of screw piling is it is easy to install. The screw piles used for this process can already be installed using a track excavator or a mini excavator paired with a low-speed high-torque hydraulic motor. Using these tools instead of a crane and other large equipment makes screw piling more convenient to carry out. It can also make the whole process faster, allowing projects to proceed continuously.
• Immediate Loading: Screw piling also allows the screw piles to be loaded right away after their installation. Even though concrete is still present in this process, a contractor does not have to wait for it to harden. The load-carrying capability of screw piles permits fast installation of the foundation and anchors, regardless of soil conditions.
• Minimal Disturbance: Another great advantage of screw piling is it does not generate too much disturbance on site. Installing screw piles and helical anchors does not produce soil cuttings, making the site clean. And with a minimised need for cleaning, it makes the whole project to be much cheaper compared to other foundation processes. Vibrations and noise are likewise expected to be minimised, making screw piling suitable for delicate projects.

Primary Applications of Screw Piling

One more advantage of screw piling is it is versatile. For a long time, screw piling has helped generate foundations that are needed by many properties. And with all the previously stated advantages, it can be utilised in areas where other foundation works tend to struggle with. Some applications of screw piling are the following.

• Sites with Limited Access: Screw piling is best utilised in remote areas or places with limited access since it only requires mobile tools to install screw piles. This process can even maximise modular screw piles and helical anchors, making it possible for the contractors to transport these things to remote areas without any issues.
• High Groundwater Conditions: Sites with shallow groundwater conditions can also be used with screw piling. The components of screw piling are expected to be not affected despite being exposed to these conditions. This feature makes it possible for the construction project to be done quickly without spending too much money.
• Earth-retaining Projects: Installation of screw piles on a batter is also possible since they can be installed at almost any orientation. Hence, earth-retaining projects can conveniently take advantage of screw piling with no difficulties.
