Le Roux pitfall to avoid

Clay soils and former iron mines.

The Sambre valley saw iron and blue-stone extraction activity until the early 20th century. Clay to clay-silt soils dominate. Demand a G2 soil study before deed and consult the Walloon mining cadastre. Reinforced foundations and drainage to verify at reception.
