Ground Screw & Screw Pile - Design and Certification

BaseDrive provides design, testing, certification and engineering support for ground screw and screw pile foundations. From early-stage planning through to certification, we ensure your foundation system is specified correctly, validated on site, and aligned with structural and compliance requirements.

We work alongside builders, architects, and engineers to deliver foundations that are not only practical to install — but engineered for performance and approval.

Engineered Foundations — Not Guesswork

Every structure requires a foundation system that matches its load, design, and site conditions.

We provide design and specification services to determine:

  • The number of screws required
  • Correct positioning and layout
  • Appropriate screw type, diameter, and length
  • Load capacity and distribution

This ensures your foundation is designed to perform — before installation begins.

Design & Specification Services

Whether you are working from full plans or early-stage concepts, we can support the foundation design process.

Our screw piles are the perfect choice.

  • Review of architectural and structural drawings
  • Screw layout and spacing design
  • Selection of appropriate screw pile systems
  • Alignment with structural load requirements

For smaller projects, we can provide practical design guidance without the need for full engineering documentation.

Pull Testing & On-Site Validation

Ground conditions can vary significantly — which is why validation is critical.

We carry out pull tests to confirm load capacity and ground suitability, ensuring the selected screw system performs as required.

  • On-site pull testing to validate capacity
  • Verification of ground conditions
  • Data to support engineering and compliance
  • Reduced uncertainty before or during installation

Engineering & Certification Support

We work alongside engineers to ensure your foundation meets structural and compliance requirements.

Pull test data and design inputs can be used to support engineering sign-off and certification where required.

  • Collaboration with structural engineers
  • Support for PS1 / PS4 documentation (if applicable)
  • Engineering validation of foundation systems
  • Confidence for council approval and project stakeholders

Our Process

iconbg1
Enquiry & Project Overview

Get in touch and tell us what you’re building. We’ll discuss your site, structure type, access, and timeline to understand what’s required.

iconbg3
Site Assessment & Screw Selection

We assess ground conditions, load requirements, and layout to determine the correct ground screw type and placement.

iconbg2
Precision Installation

Ground screws are mechanically driven using specialised machinery into the ground with millimetre accuracy.

iconbg4
Ready to Build

Once installed, the foundation is immediately load-bearing and ready for construction.
No curing time, no delays — your builder can start straight away.

7 Frequently asked
‍questions About Design and Engineering Services

A pull test measures the load capacity of a ground screw or screw pile in the actual soil conditions on site. It helps confirm that the foundation system will perform as required and provides data to support engineering and compliance.

For many structural projects, engineering is required to confirm load capacity and compliance. We work alongside engineers and can provide supporting data such as pull test results to assist with this process.

Yes. We can determine the number, position, and type of screws required based on your structure and site conditions.

Yes. We regularly collaborate with architects and engineers to ensure the foundation system aligns with the overall design and structural requirements.

Ideally during the planning or early construction phase. Early input reduces risk, avoids redesign, and ensures the project can proceed smoothly.

Yes. Pull testing can be carried out early to validate ground conditions and confirm the appropriate screw system before full installation begins.

We work alongside engineers to ensure your foundation meets structural and compliance requirements.

Where required, we can support documentation and certification to provide confidence for councils, builders, and project stakeholders.
