Gravel Driveways on sloping ground east of the Itchen valley — the kind found across Bitterne — means loose aggregate held by a stabiliser grid or edge restraint over a permeable membrane and sub-base. Locally, the driveway most often needed is one dealing with plots with a genuine fall, where getting the drainage right matters more than the surface chosen. It is best suited to long approach drives and period properties where a hard-edged surface would look wrong, though without a genuine edge restraint the stone will migrate onto verges and lawns. There is also the Itchen-valley slope, which affects how drainage runs across the plot to plan around.
About Gravel Driveways
A properly built gravel driveway is loose aggregate laid over a permeable membrane and a compacted stone sub-base, usually held in place with a honeycomb stabiliser grid or a firm edge restraint so the stone doesn’t migrate, rut under tyres, or spread onto lawns and verges. Because water passes straight through the loose aggregate rather than running off the surface, gravel is naturally free-draining without needing a specialist permeable system, and it is straightforward to top up over time rather than replace outright. It suits long approach drives, rural and semi-rural settings, and period properties where a hard-edged sealed surface would look at odds with the house, though it needs a genuine edge restraint to stay tidy rather than simply being tipped and left.
Best suited to: long approach drives, rural and period properties, and anywhere a soft, traditional look is wanted
Less suited to: steep gradients without extra stabilisation, where loose stone will migrate downhill under normal driving
Ground & property in Bitterne
Bitterne sits on sloping ground east of the River Itchen, and the 1930s to 1960s semis that make up most of the area often have a noticeable fall across the plot. On ground like this, getting the falls and drainage right matters more to how a driveway performs long-term than which surface material is chosen.
