The connection of the waterproofing layer to the floor well takes place either via a traditional clamp frame connection for waterproofing foil or for plastic mat.
The joist depth for the Enduce E2 floor well is 139 mm. Calculations are available for the influence of the floor well on the load-bearing capacity of concrete joists.
Enduce floor drain is significantly safer from a Legionella perspective than insulated cold water pipes run in conduit shafts together with HVAC pipes.
