The connection of the waterproofing to Enduce E1 is done via traditional clamping frame connections for either waterproofing foil for tiled floors, or for plastic carpet.
For concrete floors, the concrete cover layer under the floor drain should be about 70 mm to ensure fire EI 60 without further fire tests or thermal conductivity calculations.
Enduce floor drain is significantly safer from a Legionella perspective than insulated cold water pipes run in conduit shafts together with HVAC pipes.
