Helical Screw Pile Foundations FAQs
Whether you’re a construction professional, a homeowner considering helical screw pile foundations options, or simply curious about this innovative technology, below you will find the fundamental aspects of screw piles, from their construction and installation processes to their benefits, applications, and potential challenges.
What are helical screw pile foundations?
Helical screw pile foundations or screw anchors are deep foundation elements used to support various structures, such as house extensions, new buildings, bridges, and decks. Additionally, they consist of a steel shaft with helical plates or blades that are screwed into the ground, thereby transferring the load of the structure to stable load-bearing strata.
How do screw piles work?
Foundation Helical Piles work on the principle of helical rotation. The helical plates act as rotating screws, advancing into the ground with minimal soil disturbance. This helical action allows the pile to generate significant bearing capacity, providing a stable foundation for the structure. See AB Chance Helical Screw Pile Installation Process.
What are the advantages of using screw piles?
Some advantages of using this system include rapid installation, minimal site disturbance, suitability for almost all soil types, high load-carrying capacity, cost-effectiveness, Â ability to load immediately after installation, small installation equipment for ease of access, avoids damage to tree roots.
Are helical screw pile foundations suitable for both residential and commercial projects?
Yes, helical screw pile foundations are suitable for both residential and commercial projects of various sizes. Helical piles can be used for anything from small residential decks and house extensions to large commercial buildings. See our screw pile case studies.
Can screw piling be applied in various soil types?
What is the load-carrying capacity of helical screw piles?
The load-carrying capacity of screw piles depends on factors such as soil strength, pile dimensions, and installation depth. Additionally, screw piles can typically support loads ranging from a few kN to several hundred kN. Furthermore, torque correlation is used to confirm the design once pile capacity is achieved.
See Capacity Charts.
Are they environmentally friendly?
Yes, they are considered environmentally friendly because they produce minimal soil disturbance, they are super-friendly around for piling in root protection areas, and for temporary structures. They can be removed and re-used, leaving a smaller carbon footprint compared to traditional concrete foundations.
Can screw piles be installed in areas with limited access?
Yes, our systems are suitable for both domestic and commercial restricted access piling areas since they can be installed using portable equipment and require minimal space for access and installation. If you can walk through the door, we can install screw piles! View our Screw Pile Case Studies.
Can screw piling installation be carried out during winter or in cold climates?
Yes, helical screw piling installation can take place during winter or in cold climates, as the process is not significantly affected by freezing temperatures.
Is there any noise disturbance during installation?
Installation typically produces minimal noise and vibration compared to other foundation methods, making them favourable for urban or noise-sensitive areas.
Are there any limitations to using this system?
While screw piles are versatile, they may not be suitable for certain soil conditions or very heavy structures. Site-specific engineering is crucial to determine the appropriate foundation solution.
How does screw piling compare to traditional foundation methods?
Screw piling offers advantages over traditional foundation methods, such as quicker installation, reduced excavation, and minimized environmental impact. It is also safer as the screws are not susceptible to seasonal ground movement that causes subsidence and ground heave that can occur in the top 3 metres, particularly if there are trees nearby.
Do your Helical piles meet building codes and regulations?
Our AB Chance Helical piles are SCI certified so that they meet the standards.
Are screw piles resistant to corrosion?
Our AB Chance screw piles are made hot dipped, galvanized solid steel, making them durable and resistant to corrosion.
Can screw piles be removed and reused?
How long is the installation process?
Installation times vary depending on the project size and soil conditions. In many cases, screw piles can be installed in a matter of hours; consequently, this significantly reduces construction time compared to other foundation methods, averaging 20 minutes per pile to install.
