Why does the ground in Gwent matter for structural repairs?
Gwent has a mix of ground, with clay in some places and firmer rock in others. Historic coal workings are recorded beneath parts of Gwent, and a coal mining search is worth checking where movement is unexplained. Typical buildings in Gwent: Valley terraces on steep hillsides, Victorian houses in Newport and Abergavenny, and post-war estates.
