Clear technical context, with the boundaries left visible.
How ground screws work
A practical explanation of how a helical ground screw transfers structural loads into suitable ground, and why installation response matters.
Ground types and installation response
Clay, sand, chalk, gravel, made ground, rock and mixed conditions can produce very different installation responses.
Ground Screw Spacing: How Far Apart Should Ground Screws Be?
Ground screw spacing depends on structural loads, ground conditions, screw size and the subframe above — there is no single spacing measurement that suits every project.
Ground screw testing and verification
What site-specific testing can contribute, what it cannot prove on its own, and why the test requirement must match the project.
Ground screws near trees and restricted sites
How reduced excavation may help around established landscapes, and why root protection and access still need site-specific planning.
Ground screw foundation applications
Considerations for garden rooms, decking, extensions, modular buildings and ground-mounted solar support.
Ground Screws for Modular Buildings & Structures
How ground screw foundations can support modular buildings, offices, classrooms and other prefabricated structures — and where ground conditions and design still need to be checked.
Ground screws vs concrete foundations
A balanced comparison of excavation, programme, site impact and design considerations—without pretending one method suits every site.
Ground screw installation process
The practical stages around an installation: project review, setting out, installation response, connections and evidence.
When ground screws may not be suitable
A responsible foundation decision includes knowing when the ground, structure or site may point to a different approach.
