Ground Screw and Helical Screw Pile Foundations for Modular Buildings

Modular buildings are known for their outstanding efficiency and flexibility – and they're best paired with foundations that match. Our instantly load-bearing ground screw and helical screw pile foundations provide a swift, dependable, and eco-friendly solution for shipping containers, modular offices, classrooms, and site cabins.

The benefits of screw foundations for modular buildings

  • Rapid Installation

    Fast and effective installation which requires no digging or concrete, creating an immediate foundation for your modular building.

  • Tested and Quantifiable

    Our ground screws can be compression load tested, and our helical screw piles are installed with calibrated torque monitoring. Both produce certified data to prove reliability and suitability for your site.

  • Designed to last

    Our ground screws are fully galvanised to BS EN 1461:2009. Our helical screw piles are manufactured to EN 1090-1 (CE/UKCA), ISO 3834 (welding quality), and EN ISO 1461 (hot-dip galvanising). All products are CE-approved.

  • Immediately load bearable

    Both ground screws and helical screw piles are immediately load-bearing, so as soon as they are installed, your modular building can be craned into position.

  • Permanent or temporary structures

    Suitable for permanent or temporary structures and easily removable without site damage – ideal for modular buildings that may need to be relocated.

  • Environmentally friendly

    Reduced CO2 compared to pouring concrete. Helps protect habitats and prevent damage to tree root systems.

  • Minimal Disruption

    Screw foundations produce minimal vibration and noise – ideal for live school sites, hospitals, and operational commercial premises where disruption must be kept to a minimum.

  • Modular Offices

    Whether you're setting up temporary office spaces or constructing permanent modular office buildings, our screw foundations provide a stable base, enabling efficient, seamless office operations.

  • Temporary Classrooms

    We support schools and universities relocating their classrooms to modular buildings due to the RAAC crisis. Our ground screws and helical screw piles offer a reliable foundation for these structures, ensuring a safe learning environment.

  • Shipping containers

    Shipping containers are increasingly popular for their versatility in various applications, including storage units, mobile offices, or even residential spaces. Our ground screws provide a sturdy base for these containers, enhancing their stability and usability.

  • Site Buildings

    Whether you need on-site facilities for construction projects, events, or temporary accommodations, our screw foundations offer an efficient and durable solution. From site offices to welfare units, we ensure that your site buildings are securely anchored.

  • Marketing suites

    Marketing suites serve as essential spaces for showcasing properties, products, or services to potential clients. Our ground screws and helical screw piles provide a reliable foundation for these structures, ensuring stability and a professional finish.

Helical screw pile foundations for larger modular developments

For larger modular buildings, multi-unit developments, or permanent installations requiring building control certification, our helical screw pile foundations provide the step up in capacity and documentation:

  • Machine-installed using tracked machines or excavators from 1.5t to 20t with calibrated torque monitoring
  • Handles substantial compression, tensile, and shear loads – essential for multi-storey modular buildings and heavier commercial units
  • Can be installed at a range of angles to suit design requirements
  • Every pile produces a comprehensive torque pile log recording installation torque, depth, pile identification, and performance data
  • Certified load capacity reports generated through deep foundation software
  • Stock sizes from 76R to 140R, with bespoke manufacturing for specific project requirements
  • Manufactured to EN 1090-1 (CE/UKCA), ISO 3834 (welding quality), and EN ISO 1461 (hot-dip galvanising)
  • Not weather-dependent – installation carries on in conditions that would delay concrete
  • Safe and practical for use on contaminated land
  • Design life of up to 100 years

Ground screws for lighter modular units and site cabins. Helical screw piles for permanent buildings and larger commercial developments. One supplier, one installation team, one set of documentation.

Professionally Installed and Certified

Secure your modular buildings with our premium ground screws and helical screw piles for enduring support, whether they’re in place for a few months or for many years.

Our expertly trained installers conduct thorough site surveys, load testing with detailed reports, and professional installations. 

For ground screw projects, we provide compression load testing with a comprehensive findings report. For helical screw pile installations, every pile is installed in strict accordance with the engineered design criteria, with continuous monitoring to verify that the required installation torque and depth are achieved.

  • Hot-dip galvanised to BS EN 1461:2009

Frequently asked questions

  • Ground screws are well suited to lighter modular units such as site cabins, welfare units, and single-storey portable buildings. For larger, heavier, or permanent modular buildings – particularly multi-unit developments or those requiring building control certification – helical screw piles provide the additional load capacity and certified torque pile log documentation.

  • Yes. Our helical screw piles handle substantial compression, tensile, and shear loads, making them suitable for multi-storey modular construction. Every pile is machine-installed with calibrated torque monitoring, producing verified performance data for structural engineer and building control sign-off.

  • Yes. Both ground screws and helical screw piles are fully reversible. If your modular building needs to move to a new site, the foundations can be removed cleanly with no lasting impact on the ground – and in many cases the screws themselves can be reused.
