The manufacturing process for our tanks consists of assembling strips of technical fabrics using high frequency welding. These fabrics are composed of a polyester weft (a frame guaranteeing their strength), coated with PVC or PU and protected with an anti-UV treatment on both sides.

Inventor of the flexible tank, our manufacturing methods and choices have evolved with the sole aim of offering the best storage for your liquids. We offer you suitable fabrics, which we select and develop with French and European companies, according to the technical characteristics of each liquid. These fabrics are also certified to comply with the regulations in force in the sectors with which we work, and guarantee the longevity of your flexible storage.
