In addition to pools, which are filled with bathing water of drinking water quality to DIN 19 643, brine pools and their surrounds are subjected to chemical exposure from minerals and salts. The waterproofing and installation systems used in these areas must be resistant to these. As a rule, the concrete construction as well as the mineral-based levelling layers are protected against water aggressive to concrete, by these waterproofing and installation systems.
The optional use of a conductive strip and conductive lacquer between primer and the waterproofing membrane gives the possibility of a non destructive test for watertightness of the membrane using a spark coil test to DIN 55670 under high voltage. The time consuming and costly test via a 14 day trial fill of the pool with water can be dispensed with.
