    Wasserbillig, à la confluence Sûre/Moselle, cumule risque inondation et nappe phréatique très haute : caves systématiquement humides et infiltrations latérales fréquentes. Le port et la zone d’activité ont laissé un sous-sol localement pollué exigeant une expertise prudente.

    Why a sworn damp expert in Mertert?

    A "free expertise" is generally performed by a sales rep who will then sell the in-house solution. In Mertert as anywhere in Luxembourg, the diagnosis we coordinate is paid but independent: the real cause is identified objectively. HUMINUS then carries out the works that fall within its scope (MVHR, ventilation, indoor air quality) and refers you to the right specialist for the rest. The report is admissible by your insurer, building manager or a court.
