After an unusually hot summer and one of the driest years on record, clay soils across France are shrinking, causing widespread damage to homes. In Pessines, near Saintes in the Charente-Maritime region, residents are reporting significant structural issues, including cracks along chimneys and on building facades. Marc, a local homeowner, described horizontal cracks at the base of his house and subsidence in the foundation. He estimates repair costs could exceed 30,000 euros, and he noted that more than half of the homes in the area show visible signs of damage. This phenomenon, known as "retrait-gonflement des argiles" in French, refers to the shrinking and swelling of clay soils due to changes in moisture levels. When clay dries out, it contracts, causing the ground to sink and leading to foundation shifts. Karthi Mick, an architect with Global Expertise, has observed similar problems in Chapelle-la-Reine, Seine-et-Marne, where a client discovered cracks in both the ceiling and concrete floor. Mick reported that such cases are becoming more frequent, with one to two new requests arriving daily. According to Édouard Vieillefond, director general of the Caisse centrale de réassurance, the financial impact of these issues could be enormous. He estimates that repairing the damage could cost up to 500 billion euros over the next century, with each affected home requiring at least 40,000 euros in repairs. However, insurance coverage is limited, as only areas officially declared natural disaster zones are eligible for compensation. Vieillefond stressed the need for preventive measures, such as regularly checking gutters, roof leaks, and tree roots that might affect soil moisture. He also suggested using tarps to prevent moisture from rising and called for increased government subsidies and stricter building regulations to address the growing problem. Despite these recommendations, even newer homes are experiencing cracks, suggesting that current construction standards may not be sufficient to handle the increasing frequency of extreme droughts.
