Inspection

The Rain Bloc compact 300 modules themselves cannot be inspected. In order to enable an inspection
nevertheless, what are known as partial drainage pipes can be used. These are laid around the perimeter
of the infiltration ditch and connected to the ditch via shafts (see Figure 16). Alternatively, the infiltration
layer can be subdivided and the partial drainage pipes can be integrated centrally (see Figure )
