Areas in France that are subject to subsidence and cracking

Introduction

The French government provides a guarantee for insurance companies that provide compulsory natural disaster insurance cover through the Caisse Centrale de Reassurance (CCR). Please click on House insurance in France to get more information on this.

The insurance system is based on a law that came into force in 1982 and is aimed at protecting all French citizens against natural disasters such as flooding and subsidence due to dessication of the soil beneath foundations.

Gelogical mapping

Recent droughts have caused a constant increase in the cost of subsidence claims between 1989 and 2000 and these are reported to have amounted to 3,200 million euros in total over this period. As a result a massive effort has gone into mapping all the departments that are susceptible to subsidence and currently 44 departments have been mapped in detail. These tend to be concentrated on the main river basins in France and hence include nearly all South West France but surprisingly not Department 16 - Charente.
