The structural geometry around the structural waterproofing must always be defined in the knowledge of the waterproofing structure to be made, involving the specific characteristics of the waterproofing structure.

In this context, we would refer in particular to the rules and regulations for structural waterproofs using bitumen adhesives.

As well as the structural design in principle, there are a number of other factors which play a role:

— designing the concrete base and protective layers (see DIN 18195-10 [95])

— designing the structural joints (movement joints)

— structural joints in common sealed tanks

— structural joints between separate sealed tanks

— design of embedded parts.
