Where ModuSense Adds Value
Supporting installers, architects, engineers and project teams with practical and technical expertise across ground screw foundation design, specification and implementation.
Ground Screw Feasibility
Assessing whether ground screw foundations are appropriate for a project, taking into account structural loads, ground conditions, tree influence, site constraints and the required design life.
Technical Coordination
Coordinating between installers, structural engineers and project teams to ensure ground screw foundations are correctly specified, tested and supported by the appropriate technical documentation.
Foundation Strategy
Developing appropriate foundation strategies for modular, lightweight and traditional construction, including the integration of ground screws with GRP, steel and timber structural systems.
Technical Understanding of Ground Screw Foundations
Ground screw foundation design requires more than installation knowledge. ModuSense considers the relationship between structural loads, ground conditions, foundation testing and verified installation data to support a properly coordinated foundation strategy.
Load Behaviour & SLS Point Loads
Understanding how structures apply serviceability limit state (SLS) loads, typically expressed in kilonewtons (kN), is critical when designing screw foundation layouts.
Installation Verification & Pile Logs
Installation records such as pile logs and torque readings provide important verification that the foundation has been installed correctly and performs as expected.
Torque Measurements & Testing Data
Installation torque measurements can provide valuable insight into ground resistance and foundation performance when interpreted alongside verified load testing data.
Factors of Safety in Foundation Design
Foundation systems must incorporate appropriate factors of safety (FOS) to ensure loads remain within safe structural limits.
Advantages of Ground Screw Foundations
Ground screw foundations provide an alternative to traditional concrete foundations, particularly where excavation, spoil removal or ground disturbance are undesirable.
Because screw foundations are installed rather than excavated, they can significantly reduce the amount of disruption on site while still providing structural support for extensions and modular buildings.
In areas where clay soils and tree influence affect foundation design, screw foundations can sometimes provide an approach that avoids deep trench excavation and the challenges associated with traditional foundations.
Ground screw installation can also be considerably faster than traditional foundation construction, allowing projects to progress more quickly while reducing the environmental impact associated with large volumes of concrete.
ModuSense helps project teams determine when ground screw foundations are appropriate and how they should be integrated into the wider structural design. This includes considering structural loads, ground conditions, testing requirements and the supporting technical evidence required for a coordinated and compliant foundation solution.

Ground Screw Foundations guide.
Ground Screw Foundation Knowledge
Ground screw foundations are a specialist area of ModuSense consultancy, combining practical installation experience with an understanding of structural loads, ground conditions, testing and verification. Our technical knowledge helps project teams understand when these systems are appropriate and how they can be incorporated effectively into the wider construction strategy.
Ground Screw Foundations for Extensions
Ground screw foundations are increasingly explored as an alternative to traditional trench foundations for extensions and lightweight structures.
Understanding Ground Conditions
Soil type, clay shrinkage, tree influence and installation torque all affect how ground screw foundations behave.
Ground Screw vs Concrete Foundations
Comparing screw foundations with traditional concrete foundations requires understanding load behaviour, soil conditions and installation constraints.
Engineering Considerations
Proper structural design requires understanding point loads, installation verification and appropriate factors of safety.
GRP and Modular Floor System Expertise
ModuSense works across a range of structural systems, with particular expertise in the integration of ground screw foundations with lightweight modular construction and glass-reinforced plastic (GRP) structural floor systems.
Understanding the complete load path — from the structure and floor system through to the foundation and supporting ground — allows foundation requirements to be considered as part of the wider structural strategy rather than as an isolated element.
This specialist knowledge has also informed the development of ModuFloor®, our pre-engineered GRP structural floor system for modern extension and modular construction.
