Winchester's Chalk Geology Demands Expert Preparation.
Winchester sits on England's great chalk aquifer — the same bedrock that created the Cathedral city's famous water meadows. While chalk offers excellent drainage and bearing capacity, it requires careful excavation. Some areas have clay caps or dissolution features that need proper assessment.
At JustBases, we've spent years working across Winchester's distinctive terrain. Whether you're in the grand gardens near St Cross, the hillside slopes of Stanmore, or the village plots of Hursley and Twyford, we prepare your sub-base correctly for your specific conditions.

Need Help Choosing Your Winchester Shed Base?
"Hi, I'm Craig. Winchester's chalk is generally fantastic for foundations — good drainage, solid bearing capacity. But I've also seen clay pockets near the Itchen and some sloping sites around St Cross that need careful thought. If your garden has a slope, sits near protected trees, or you simply want to talk through your options, give me a call. My family's been doing this work for over half a century."
