    Dominant building stock in Mertert

    A Moselle river commune: Wasserbillig on the banks of the Moselle (older houses, 1970s-80s apartment blocks), Mertert village (rural building stock and recent developments).

    Observed damp pathologies

    Wasserbillig, at the confluence of the Sûre and Moselle, combines flood risk with a very high water table: cellars are consistently damp and lateral infiltration is common. The port and industrial area have left locally polluted ground requiring a cautious survey.

    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.
