Netherlands faces growing crisis as drought threatens hundreds of thousands of home foundations

While autumn weather has finally arrived in the Netherlands, the aftereffects of last summer's extreme drought are lingering in a very physical way. Homeowners across the country are returning from their holidays to find fresh cracks in their walls or doors that refuse to close properly. This is not just a cosmetic issue, but a symptom of a systemic crisis involving the very stability of Dutch housing. As the ground dries out, clay and peat soils shrink, often pulling the earth away from the shallow foundations of older homes.

A looming threat for homeowners

Deltares, a Dutch research institute specializing in water and soil, has been monitoring the situation closely. When clay soil loses its moisture, it contracts, which can lead to structural shifting in homes that lack deep-piled foundations. This is particularly problematic in provinces where the soil composition is soft. Soil expert Otto Levelt warns that history is repeating itself. Similar to the record-breaking dry year of 2018, we are seeing a spike in property damage that is likely to become the new normal as weather patterns grow more volatile.

Recent data suggests that approximately 425,000 houses are currently suffering from foundation issues or are at high risk of developing them. Even more concerning, the KCAF foundation, a national knowledge center for foundation issues, predicts that this number could climb to nearly 690,000 within the next thirty years. With the total cost of necessary repairs estimated at over 11 billion euros, the financial burden on individual owners is staggering. Many simply cannot afford the tens of thousands of euros required to stabilize their homes, leading to a precarious situation for thousands of families.

We believe that every house should have a home passport. It would allow people to know everything about the state of their property and its underlying foundation.

This call for transparency from Frank van Lier of the KCAF highlights a major gap in the current market. Since April, real estate valuations must include an indication of foundation quality, but these reports are often based on general area data rather than site-specific engineering inspections. For expats and new arrivals, this means buying a home in the Netherlands requires extra caution. If you are looking to purchase property, specifically in areas with older construction or soft soil, ensure your structural survey includes a professional assessment of the foundation to avoid inheriting a hidden financial disaster.

Adapting to a changing climate

Addressing this issue is not just about repairs, but about prevention and smarter building practices. Experts suggest that we must move toward climate-resilient construction. This could include techniques like covering clay areas to prevent dehydration or installing drip irrigation systems to keep soil moisture levels constant. While these solutions are effective, they require a shift in both government policy and homeowner mindset, as many currently prefer to ignore the warning signs until damage becomes impossible to hide.

The complexity deepens when considering homes built on piles, which can suffer from rot if groundwater levels drop too low. Because groundwater management is a regional and municipal responsibility, individual homeowners have very little control over the conditions beneath their own feet. Tenant rights groups and homeowners associations are now calling for greater government intervention to provide financial support for those who are facing insolvency due to these structural costs.

Ultimately, the path forward is as much political as it is technical. With so many citizens unable to absorb the repair costs, discussions are ongoing about potential subsidies or specialized loan structures. For now, the housing market remains under a dark cloud, as the stability of the home, a hallmark of the Dutch dream, faces a literal and figurative erosion.
