Ground screws in Shaftesbury
A smart foundation for Shaftesbury's sloping gardens
On a garden that falls away, a traditional base may involve cutting into the slope, building up levels and removing a considerable amount of soil. Ground screws can create the level support plane above that changing ground with a much lighter touch.
JustBases works out the support positions, finished heights and installation method for you. Start by telling Craig about the garden building and its approximate footprint.

Your enquiry
Ground screw installation in Shaftesbury
Local knowledge, handled by us
Hilltop ground and changing levels, handled by us
Shaftesbury's position on a steep Upper Greensand escarpment gives the town its views and many gardens their distinctive levels. Conditions still vary from plot to plot, so we use the actual site rather than expecting customers to make a geological judgement.
Our team plans the grid around the building, observes installation and confirms the completed supports before the frame is fitted.

A simpler way to build the base
Why choose ground screws instead of a dug base?
For a sloping Shaftesbury garden, ground screws can avoid the cost and disruption of excavating the whole footprint flat while still creating a properly level base.
| Factor | Ground screw foundation | Excavated concrete or aggregate base |
|---|---|---|
| Slope treatment | May bridge a stable moderate fall | May need more digging or built-up levels |
| Spoil | Limited | Can mean much more soil to remove |
| Obstructions | The support plan can often be adjusted | Wider digging can reveal and remove them |
| Time before framing | After checks | After cure |
Craig will look at the building and plot before recommending a foundation. JustBases can also discuss other base systems if the project calls for one.
Easy to arrange
Stepped garden or narrow hill street? Let us plan it
Ground screws reduce the number of heavy materials entering the garden and the amount of spoil coming out, which can be valuable on stepped plots and properties with limited parking.
There is no complicated access exercise for you. Share a photo if handy, and Craig can arrange a site visit when seeing the route or slope is the easiest answer.

Helpful local information
Shaftesbury planning links, kept helpful
Many domestic garden buildings can use permitted development rights. Any restriction generally relates to the completed building's dimensions, use, position or property context—not simply to its ground screw supports.
Dorset Council provides planning and conservation information for individual properties. You can use those links when relevant while still asking us for an initial foundation price.
You do not need to settle every planning detail before speaking with us. The links are here if they help, and Craig is happy to explain which parts relate to the base.
