Why does the ground in Hampshire matter for structural repairs?
Much of Hampshire sits on clay that shrinks in dry summers and swells in wet winters. Ground movement here is more often linked to soils, drains and trees than to mining. Across Hampshire, most homes are Victorian terraces in Portsmouth and Southampton, 1930s semis, and large post-war and new-build estates.
