Your enquiry
Ground screw installation in Dorset, Hampshire or South Wiltshire
Why choose ground screws?
A cleaner, faster route to a level garden-building base
No concrete curing delay
The approved support frame can follow the final level and installation checks without waiting for a concrete slab to cure.
Useful for difficult access
Ground screws can reduce the need to move skips, aggregate and wet concrete through narrow side routes or established gardens.
Level support on changing ground
Individual support heights can help form a level base across many sloping or uneven gardens, subject to the real site and building design.
Common applications
What can a ground screw base support?
Ground screws can create a level foundation for many garden buildings without excavating and filling the complete footprint.
Garden rooms and offices
A strong, accurately levelled foundation for timber or steel-framed garden buildings.
Sheds and workshops
Installed screws only or a complete base with a timber support frame supplied by JustBases.
Cabins and studios
A clean foundation option where access, garden levels or reducing excavation are important.
Bespoke garden buildings
Support positions coordinated with the building footprint and the frame requirements supplied for the project.
How we install the support base
Accurate set-out, powerful installation and laser checks
The same three shared images used on our local ground-screw pages show the installation sequence clearly.

★★★★★
"Craig and his team have been fantastic. Had the team over twice now to help with our garden project and both times I've been super impressed with the work. The team are extremely hard working but most important to me is the quality of their workmanship. The fencing looks amazing and the cabin was spot on in terms of dimensions and perfectly level. I would highly recommend."
