Less excavation and spoil
Ground is displaced by the screw rather than excavated for a full slab, which can reduce skips, wheelbarrowing and disruption.

Ground screws in Broadstone
A cleaner way to support your Broadstone garden room
Ground screws create a precise grid of steel supports without digging out the entire base area. That means less spoil, fewer heavy materials moving through the garden and no wait for concrete to cure.
We recently installed a 7m × 4m ground screw foundation in Broadstone using 1.25-metre hot-dip galvanised steel screws. It was prepared for a timber-framed garden room and demonstrates the same careful set-out and laser levelling we bring to every project.

Your enquiry
Ground screw installation in Broadstone
Local knowledge, handled by us
Broadstone experience, explained simply
Broadstone gardens can include both sandy and clayey ground, sometimes changing over a short distance. You do not need to work out which type you have before calling us.
We use the building details, what we see on site and the response during installation to make sensible decisions. Craig will explain the recommendation clearly and let you know if another base would suit the garden better.
What we check for you
- 1 We plan the support points around the building frame
- 2 We select the screw specification for the job
- 3 We monitor installation and finished height
- 4 We leave a level grid ready for framing
Why choose ground screws?
A cleaner, faster foundation for your garden building
Level base on a fall
Head heights and the supporting frame can accommodate moderate level changes without building up a large mass of concrete.
Ready for the frame
There is no concrete curing period, so the correctly specified frame can follow once the foundation has been checked and accepted.
Ventilated construction
A suspended timber floor can retain airflow beneath the building when the frame, membranes and perimeter details are designed correctly.
Targeted footprint
The foundation is concentrated at designed support points instead of covering the whole garden-room footprint with a slab.
Long service potential
The hot-dip galvanised screws we use have an expected in-ground lifespan beyond 50 years when correctly specified for the site.
Common applications
What can a ground screw base support?
From garden rooms and offices to sheds and studios, ground screws create a strong, level base without filling your garden with excavated soil or wet concrete.
Garden rooms and offices
Timber-framed rooms, studios and workspaces of many common sizes.
Log cabins and summerhouses
Suspended bases that keep the building level and separated from direct ground contact.
Sheds and workshops
From lighter storage buildings to more substantial timber workshops.
Decking and garden structures
Point foundations for raised decks, pergolas and similar structures where the connection detail is suitable.
Our Broadstone installation process
Accurate set-out, powerful machinery and laser-checked levels
These images show the simple sequence behind the base: supports positioned for the building, screws installed with purpose-built machinery and the completed grid ready for its frame.
-
1 Careful measurements establish the support grid.
Position the supports
We mark and square the footprint, then place the screws into pilot positions that match the planned timber frame.
-
2 The machine provides the torque; the laser keeps the grid level.
Machine-install and level
A purpose-built high-torque driver installs the 1.25-metre screws while our laser controls the finished heights.
-

Fit the building frame
Once the support grid is complete, the timber frame can be attached without waiting for concrete to cure.

These are guide prices for standard installations. Your free written quotation confirms the exact price for your building and garden, including any support frame supplied by JustBases. Larger or unusual foundations are priced individually.
A simpler way to build the base
Why choose ground screws instead of a dug base?
Our Broadstone project shows the practical difference: a measured support grid instead of a full-area excavation, with the frame able to follow immediately.
| Factor | Ground screw foundation | Excavated concrete or aggregate base |
|---|---|---|
| Excavation | Localised at each support point | Usually removes soil across most or all of the footprint |
| Spoil removal | Often minimal | Typically requires disposal or reuse of excavated material |
| Sloping ground | Can support a suspended level frame | May need deeper digging or built-up edges |
| Use after installation | No concrete curing time | Concrete elements require an appropriate curing period |
| Unexpected obstacles | The support plan can often be adjusted | Wider digging can cause more garden disruption |
| Best suited to | Compatible framed buildings on verified ground | Projects needing a continuous slab or where screw installation is unsuitable |
Craig will recommend the foundation that makes sense for your building and garden. JustBases also installs other base types when ground screws are not the best fit.
Easy to arrange
Narrow access does not automatically rule out ground screws
A Broadstone postcode, the building size and a short description are enough to begin. If you already have a photo of the side gate or route, it can help us quote, but it is optional.
Ground screw work avoids many of the bulk deliveries needed for a dug base. We plan the equipment route and can pop out to look if access is unusual.

Helpful local information
Helpful planning links for Broadstone
Many garden buildings fall within permitted development rules. Any planning question normally relates to the finished building—its size, height, position and use—rather than the ground screws by themselves.
Broadstone has conservation areas, protected trees and a neighbourhood plan, so the local links are useful if your property has a special designation. You can still ask us for a base quote while you check.
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.
