Nearly 500,000 buildings across the Netherlands face serious structural subsidence issues that could cost up to 54 billion euros in damages and lost property value over the next decade.
A recent study by the Council for the Living Environment and Infrastructure warns that more than 120,000 homes already have damage severe enough to require immediate repairs.
The figure reflects not only the physical cost of fixing foundations, but also declining real estate values, municipal infrastructure repair, and broader economic fallout.
Groundwater levels and historic wooden piles
Foundation problems generally occur when groundwater levels drop, exposing historic wooden support piles to air and triggering bacterial decay, or when soft peat and clay soils shrink during prolonged droughts.
Properties in older urban areas and low-lying regions are particularly vulnerable, with common signs of trouble including diagonal wall cracks, jammed doors, and sloping floors.
Experts note that climate change is accelerating these issues, as dry summers lower the water table and destabilize buildings that have stood for centuries.
A challenge for homeowners and planners
Because foundation damage develops gradually, standard building insurance policies in the Netherlands rarely cover the repair costs, leaving individual homeowners responsible for tens of thousands of euros in fixes.
To assist affected residents, national programs like the Sustainable Foundation Repair Fund, managed by the SVn, offer specialized loans for property owners who lack the immediate financial capacity to stabilize their homes.
The advisory report recommends that future urban development strictly prioritize soil stability, though experts acknowledge this creates tension with national targets to build 100,000 new housing units annually.
Government ministries, regional authorities, and construction sector partners are currently working on a unified national strategy to address foundation safety and streamline technical inspections.
