The Allier department has been chosen by the State to pilot the Clay Prevention Fund, a new national initiative aimed at assisting owners of individual homes affected by the phenomenon of clay soil shrinkage and swelling.

This innovative scheme aims to support homeowners facing risks associated with variations in clay soil moisture, which can weaken foundations and cause cracks in homes, a problem exacerbated by repeated drought episodes. The goal is to intervene proactively to prevent significant structural damage.
The fund offers a two-phase support program. The first phase involves study and diagnosis, where a qualified professional assesses the home's vulnerability and proposes solutions. This diagnosis is subsidized between 70% and 90% based on household income. The second phase covers preventive work, such as managing rainwater or waterproofing foundations. Financial aid, ranging from 50% to 80% of the work cost, is available, with an eligible expense ceiling set at €14,000 excluding tax.
To be eligible, the property must be the owner-occupier's main residence, located in a high-risk zone for clay shrinkage and swelling (RGA), covered by home insurance, completed at least 15 years ago, not semi-detached, and with no cracks exceeding 5 mm in width. Income ceilings must also be met. Households undergoing natural disaster compensation procedures are not eligible.
Homeowners can check their eligibility and start the process by visiting the official platform: fonds-prevention-argile.beta.gouv.fr. The association SOLIHA 03 offers local support in Allier, reachable at 06 18 11 57 87 or via email at rga.allier@soliha.fr. Advisors from the Direction Départementale des Territoires et de la Mer (DDTM) are also available to answer questions.
