摘要

In order to improve the sealing of the tank (1) with a concrete wall (10), a sealing layer (2) made of flexible material is applied to an external surface of the concrete wall. A confinement structure (3) is put into place around the layer of sealing, in order to prevent the latter is detached from the wall. The structure of the confinement is passive and comprises a layer which is substantially more rigid than the sealing layer.
