Withdrawal-swelling hazard of clays (drought) in Haute-Garonne

The removal and swelling of certain clay soils has long been observed in arid and semi-arid climate countries where they are at the origin of many damage to buildings and roads. Insurance coverage of claims resulting from differential movements of land due to the removal-swelling of clays was made possible by the application of Law No. 82-600 of 13 July 1982, relating to #x27 July; compensation to victims of natural disasters. In the particular case of the withdrawal-swelling phenomenon of clays, the areas concerned, even subject to a hazard considered high, remain constructible. The requirements imposed are, for the most part, rules of common sense, the implementation of which entails only a relatively small additional cost, but compliance with which makes it possible to significantly reduce the disorders caused to the building, even in the presence of land highly susceptible to the phenomenon of withdrawal-swelling. __Origin__ Extraction from SUDOCUH Perimeters of communes of l'IGN (ADMIN EXPRESS) __Partner organisations__ DDT Haute-Garonne __Links annexes__ * [XML metadata view](http://ogc.geo-ide.developpement-durable.gouv.fr/csw/all-dataset?REQUEST=GetRecordById&SERVICE=CSW&VERSION=2.0.2&RESULTTYPE=results&elementSetName=full&TYPENAMES=gmd:MD_Metadata&OUTPUTSCHEMA=http://www.isotc211.org/2005/gmd&ID=fr-120066022-jdd-dce0aef5-32bc-496f-91f3-5a430cd250bb) [See this page on geo.data.gouv.fr](https://geo.data.gouv.fr/fr/datasets/5dae5bf5e1beec9f29e5000fdc6641999a74664d)
