In addition to many other positive properties, the impermeability of concrete stands out. This makes the material particularly suitable for container construction as well as for use as a barrier structure. The material and structural possibilities qualify concrete for constructions in the field of environmental protection, where water law requirements must be met. When it comes to components that are intended to retain water-polluting substances as a secondary barrier, they are referred to as containment structures. These require forward-thinking planning beyond the usual scope. The book provides important insights for planning, concrete composition, and construction execution. In addition to the relevant laws, regulations, and technical rules, it presents the fundamental principles of construction, stresses, as well as the design and execution of containment structures.
