Soil

Reactive clay

Moderately to highly reactive clay (Class M to H). Seasonal movement causes hairline cracking in brickwork and render. Modern slabs are engineered for it; older strip footings were not. Consistent moisture around the house is the whole game.

In the walls

  • Site classification (reactive clay) drives slab design and cost
  • Design covenants control fences, colours and even clotheslines
  • Titles and infrastructure delays in newer stages
  • Builder insolvency exposure for anything under construction
  • Leaking showers and balconies are the era's defect
  • Dozens of halogen downlights
  • Engineered stone benchtops (safe to live with, not to cut)
  • Estate covenants still in force
What each of these costs to fix
