The Sionne sand quarry, located in the Vosges, was operated by the Paul Calin company. This sand pit extracted alluvial sand and gravel, produced by washing, screening and crushing on the Barville site. The products obtained, such as semi-crushed 0/2.5 sand, rolled 0/4 sand, 0/12, 0/20 or 0/22 concrete mixes, as well as 4/8 or 4/12 gravel.
