with a membrane or sheet – this sheet is to
be connected to the Staufix SWA body with
the counter flange supplied with the 83023.
In the case that a water proof concrete is
being used then the heavy duty Kautschuk
seal (included with the 83023) is inserted
and then fixed tight with the counter flange.
Please install the Kautschuk flange properly
