What is a ground screw foundation?

A ground screw is a steel foundation element installed into the ground to provide an anchoring point for suitable structures. The appropriate design depends on soil, loads and project conditions.

Can ground screws replace concrete foundations?

For suitable applications, ground screw systems can provide an alternative to conventional concrete foundations. Suitability must be established through project and ground assessment.

Are ground screws suitable for solar projects?

Ground screws can be used as foundations for ground-mounted solar structures where the ground conditions, structural loads and installation requirements are suitable.

What information is needed for a quotation?

Useful inputs include project location, project type, solar capacity where applicable, site or soil information, structure details and the required quantity or layout.

03 / GROUND SCREW PRODUCT INFORMATION

Know the foundation before you specify it.

Ground screws are not one standard product. Configuration is selected around application, ground, loads, connection and installation requirements.

GROUND SCREW ANATOMY

From connection point to ground.

A typical ground screw system combines a connection/head arrangement, a steel shaft and one or more helical elements. Geometry is selected to work with the supported structure and ground conditions.

GeometryLength, shaft arrangement and helical configuration are selected for the application.

ConnectionHead or bracket arrangement must suit the supported structure.

Ground interactionHelical geometry and installation depth influence load transfer.

DurabilityMaterial and corrosion protection should reflect the exposure environment.

InstallationEquipment, torque, alignment and access affect execution.

Project loadingCompression, uplift and lateral demand must be considered.
