Mining and mundic
St Blazey lies inside the Cornwall and West Devon Mining Landscape World Heritage Site. Cornwall's mines left shafts and workings that aren't all mapped, which is why a mining search comes as standard here; pre-1950 concrete homes also raise the mundic question.

Ground and building stone
Under most of St Blazey the bedrock is mudstone, siltstone and sandstone (89%). Locally the slates and shales are called killas; rubble-stone and slate-hung walls are typical, and soft stone and old mortar weather over time.

Ground stability
The BGS GeoSure 5 km hexagon covering St Blazey shows moderate slope instability (landslides) potential. That's a broad screen, not a site assessment; look for cracking, sticking doors and leaning walls.
