Microgravimetry to search for cavities – Wind farm in Joux-La-Ville, Yonne, France

Innogeo investigated the site of the future wind farm of Joux-La-Ville, France. Microgravimetry measures were taken at the foundations of the future 26 windmills to detect eventual underground anomalies (cavities, cave-ins, deconsolidations). More than 2,000 measure stations were set up and measured in 3 weeks by two measuring teams operating simultaneously.
