When planning a construction or foundation project, selecting the right foundation system is crucial. Screw piles offer a sustainable, efficient, and reliable alternative to traditional concrete foundations. At ABC Anchors, we provide a comprehensive process to ensure your screw pile specifications meet the unique requirements of your site and structure.

1. Initial Enquiry: Understanding Your Needs

The journey begins with understanding your project's specific needs. Whether you're a contractor, developer, or homeowner, you will need to assess the scope of your project to determine the most suitable foundation solution. This initial assessment helps us gather essential information such as load requirements, site conditions, and access constraints.


2. Appointing a Structural Engineer

Engaging a qualified structural engineer is a pivotal step. They will assess your building plans and calculate the expected loadings. Based on this information, the engineer determines the type, size, and number of screw piles required to safely support your structure. For trusted professionals, we've collaborated with Michael Aubrey Structural Engineers on multiple projects and highly recommend their services.


3. Site Assessment and Soil Investigation

A thorough site assessment is essential to understand the ground conditions. Soil investigations help identify factors such as soil type, moisture content, and compaction levels. This data informs the selection of appropriate screw piles and ensures they can bear the intended loads.


4. Calculating Torque and Load

To ensure the screw piles perform effectively, it's crucial to calculate the required torque and load capacities. Torque is measured during installation using a gauge fitted on the torque head, providing real-time feedback. The formula Qu = Kt × T links torque to the ultimate uplift and compression capacity of the pile, ensuring structural integrity.


5. Selecting the Right Screw Pile

Based on the structural engineer's calculations and site assessments, the appropriate screw pile is selected. ABC Anchors offers a range of screw piles suitable for various applications:

  • 60R Screw Piles: Ideal for lighter loads and smaller projects.

  • 76R Screw Piles: Versatile and widely used for residential and commercial foundations.

  • 76RL Screw Piles: Cost-effective option with similar performance to the 76R series.

  • 89R Screw Piles: Designed for heavy-duty applications requiring high torque capacities.

Each pile is engineered with specific diameters and wall thicknesses to meet diverse project needs.


6. Installation Process

The installation of screw piles involves driving them into the ground using hydraulic torque motors. This method ensures minimal ground disturbance and immediate load-bearing capacity. The piles are installed to the calculated torque values, confirming their performance and compliance with specifications.


7. Final Inspection and Handover

Upon successful installation and testing, a final inspection is carried out to ensure all specifications have been met. Once approved, the project is handed over, and the foundation is ready to support the next phase of construction.
