Hermalle pitfall to avoid

Meuse floods and natural hazard.

The Lower Meuse experienced the floods of July 2021. Any construction in a hazard zone must meet the new standards (floor levels, watertightness). Require the SPW flood-hazard mapping and check the ground-floor level relative to the highest known water level.

Témoignage acheteur
« After 2021 we were cautious — the expert checked the floor level, compliant PEC +30cm. Relieved. »
