When using a sub-structure waterproofing system, the sealing system must be planned integrated. All joints of the membranes are executed as overlap joints or secured by tapes. Only products that conform to the system and have been approved by the manufacturer can be combined with the the sub-structure waterproorfing membrane. The self-adhesive strips attached to the Zemseal^® product ensure a pressurized water-tight system. Further joints are also securely sealed with the tested Zemseal^® adhesive tapes.
