Our products for transportable buildings
SGU beam screw
SGU screws are designed for light to medium-weight transportable structures, such as modular homes or small offices. These screws support design loads of up to 16kN, with extensions available for challenging terrains.
SGC adapter screw
For demanding projects, SGC screws handle heavier loads with a vertical design capacity of up to 25kN. These screws are ideal for permanent installations or sloped ground conditions. For specialised applications requiring significant height, the SGC model can be extended with extension pipes, allowing flexibility in varied terrain.
SGL bracket
SGL brackets enhance stability and distribute loads effectively when additional height or bracing is needed. For transportable building foundations, the bracket can be combined and coupled with our adapter screws SGC and SGN.

Common challenges – solved with ground screws
| Foundation challenges | How ground screws provide solutions |
|---|---|
| Diverse terrains | Suitable for all soil types, even rocky, clay-rich, or uneven sites. Can be installed with minimal preparation in challenging terrains and difficult-to-access areas. |
| Temporary structures | Easy to uninstall and reuse without site damage for projects that need removable and reusable foundations. |
| Stability | Distributes weight evenly while reducing risks of settling. Preventing shifting on varied soil conditions. |
| Tight timelines | Rapid deployment for emergency projects requires minimal equipment and no curing time. |
| Cost constraints | Reduces cost by requiring less labour, machinery, and material use. A cost-conscious solution for relocatable structures. |
Case study
Ground screw foundation system speeds up delivery of relocatable school buildings
Background
Temporary classrooms to replace ageing facilities
Ōpōtiki College, located in the Bay of Plenty region on New Zealand’s North Island, needed temporary classrooms to replace ageing facilities while new, permanent classrooms were constructed. The school’s surroundings include native flora and fauna, which makes sustainable building practices essential to preserving the natural environment.
The main contractor, Livingstone Building, worked with architects. The design group Stapleton Elliot (DGSE) delivered these relocatable classrooms, prioritising minimising disruption to students and maintaining harmony with the surrounding landscape.
Objectives
Establish temporary classroom facilities on a robust and removable foundation
The primary goal was establishing temporary classroom facilities on a robust yet easily removable foundation to preserve the natural landscape. The foundation needed to meet these objectives.
The challenge
Minimal disturbance to the school and the surrounding environment
Ōpōtiki College, situated in a sensitive and ecologically diverse area, required a solution that could be implemented quickly, with little disturbance to the school and the surrounding environment. The region’s soft soil conditions presented an additional challenge, as traditional concrete foundations could be invasive and time-consuming, requiring heavy machinery and disrupting the soil and nearby natural habitats. The project called for a foundation system compatible with temporary structures capable of withstanding New Zealand’s variable weather conditions.
The constraints included a tight timeline and the need for an environmentally friendly approach.
A traditional concrete foundation would have meant delays, more noise, and greater site disruption, which would have impacted school activities and the surrounding ecosystem.
The solution
A cantilever pile foundation suitable for relocatable structures
The StopDigging ground screw foundation system provided an ideal solution for this temporary project. The system is a cantilever pile foundation suitable for relocatable structures designed to handle challenging soil conditions without requiring extensive groundwork.
With this approach, the foundation minimised environmental impact and installation time while supporting the school’s temporary buildings.
Ensuring precise, site-specific implementation
StopDigging collaborated closely with DGSE and Livingstone, ensuring precise, site-specific implementation. Tim and his team conducted a thorough assessment, visiting the storage yard to confirm measurements and suitability. They installed SGC 89X2500 adapter screws for the classroom foundations and SGC 76X2000 adapter screws for deck piles, ensuring swift, accurate placement. This seamless process allowed the Livingstone team to quickly proceed from foundation installation to building placement.
The results
Kept the site clean and avoided excess soil removal
The project was delivered within a tight timeframe, allowing the school to maintain operations with minimal disruption. StopDigging’s system expedited installation, negated the need for concrete curing, and kept the site clean, avoiding excess soil removal and machinery-intensive work.
Reduced waste with zero-ground disturbance
Avoiding traditional concrete foundations reduced carbon emissions and preserved the natural landscape. Once the temporary classrooms are no longer required, the screws can be removed and reused, reducing waste and enabling zero-ground disturbance—a crucial benefit for projects in sensitive environmental zones like Ōpōtiki.
Client feedback
Genevieve Talbot, representing DGSE, highlighted the sustainability, speed, and ease of removal of the ground screw system. Livingstone Project Manager Sam Dunn also commended the StopDigging team, noting the system’s accuracy, efficiency, and suitability for the project’s needs.
