A simpler way to build the base
Why choose ground screws instead of a dug base?
Ground screws can transform the logistics of a Southampton project by reducing excavation and bulk material movements while removing curing time.
| Factor | Ground screw foundation | Excavated concrete or aggregate base |
|---|---|---|
| Through-house or side access | Machine route and steel components | Spoil, stone and concrete route |
| Previously built-up ground | The support plan can often be adjusted | May need more digging and replacement material |
| Moisture below floor | Ventilated void possible | Damp detailing integral to slab |
| Framing start | After final checks | After concrete cure |
Craig will recommend the foundation that genuinely suits the building and garden. JustBases can also discuss other base systems.
Easy to arrange
Side alley or route through the house? Let us help
Ground screws can be attractive on city properties because the job avoids many barrow loads of spoil, aggregate and concrete.
Start the enquiry without measuring every doorway. A phone photo is useful if handy, and we will visit when the route is easier to see than describe.

Helpful local information
Southampton planning links made simple
Many domestic garden buildings use permitted development rights. Planning usually concerns the finished building's height, use and position rather than its ground screws alone.
Southampton City Council provides local conservation and heritage information. These checks can happen alongside your foundation quote.
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.
