The invention relates to a method for the containment of pollutants present in the aquatic environment and to a device for implementing same. According to the invention, a containment material (7) is poured over the pollutant (1) in order to cover same, said method comprising the following steps, namely: i) the in situ measurement of documentation of the surface and subsurface currents and assessment of sporadic events, such as storms, that affect the location of the pollutant (1) to be covered; ii) selection of the minimum grain size to the containment material (7); iii) determination of the amount of containment material (7); and iv) deposition of the pollution source of the containment material (7) formed by at least one continuous layer of sepiolite clay (2) having a sepiolite mineral content of between 25 and 100%. In addition, a layer of granular material (3) can also be deposited thereon, said layer representing up to 99 wt.- % of the containment material (7). The device includes a rigid tube (5) which can be extended using a flexible tube (10) which is divided into sections that are separated by metal rings (9) supported by a steel cable (8). |
