Common Design Considerations of the Helcon Screw Piling System

November 20, 2022

A building cannot withstand floods, earthquakes, and other occurrences if it is not supported by a foundation. The foundation of a property intends to hold the weight of a building and keep it stable against floods, earthquakes, and other natural occurrences and ground movements. It also insulates the building, keeps moisture out, and prevents insect infiltration. 

Many materials can be employed in setting up the foundation of a building. But one material that has been effective in generating building foundations is screw piles.

Screw piles are comprised of the steel helix and high-strength steel shaft. The helix carries the pile load into the ground, especially when it is screwed within a thick geotechnical layer in the ground. The steel shaft’s free end is then connected to the building’s foundation elements. 

Advantages of Helcon Screw Piling System

At Helcon, we ensure that the screw piles we use can benefit tons of property owners throughout NSW and Australia-wide. If you will be maximising our very own Helcon screw piling system, you can expect to obtain tons of advantages over other foundation options.

One of the advantages of maximising our screw piling system is cost-saving construction time. Once every aspect of the project has been set, you can expect our screw piles to be founded in the ground in a short time. For residential houses, you can expect screw piles to be set within a day. Alternatively, screw piles can already be maximised on four to five-storey apartment block buildings within 10 days.

Another advantage of the Helcon screw piling system is it does not produce spoil and waste. The absence of these elements prevents your ground area to be free from contamination issues. You can also expect less noise and minimal vibration with our screw piling system.

Key Design of Helcon Screw Piling System

Not all buildings have similar qualities. Hence, our team dedicates a lot of time and effort to designing the Helcon screw piling system and matching it to the requirements of every building project. When designing our screw piles, we maximise the Project Structural Engineer’s screw pile footing layout alongside their screw pile design Load Schedules. Doing this allows us to determine the size of the Helix and the number of screw piles required for the project.

We then use the Geotechnical Report to find out the target founding layer in the ground to find the length of the pile and influence the final size of the selected Helix. As for understanding the RLs involved with the building structure, we maximise Architectural sections to optimise the design length of the screw pile. The pinpointed screw pile shaft must then maximise a compatible torsional strength to resist twisting failure when installing them as well as a proper effective length strength when carrying the compression loads to prevent buckling failure.

The length of the screw pile can likewise be determined by considering the footing’s depth and whether it will be installed at natural ground level or from the excavated foundation level.
