we are currently preparing everything for the screed. However, there are different opinions on how to build up the floor structure.
Our plan would be as follows:
On the raw subfloor, we would lay 4cm (1.5 inches) of insulation, then a 3cm (1 inch) fixing plate, followed by pipes for the underfloor heating, and the screed on top.
Is it necessary to place an Alujet Floorjet or a Katja foil between the raw subfloor and the insulation, or is it sufficient as is?
In the area without underfloor heating, we would put a Katja foil on the insulation and then the screed on top.
Please let us know if this is okay!
Thanks!

Benutzer 100326 Mar 2018 13:45Hello forum,
I assume you want to install a waterproofing membrane like the "Knauf Katja Sprint" or a similar product.
This membrane is designed according to DIN 18195 or 18533 standards to protect against rising damp from the ground.
Therefore, it only makes sense to use it in rooms on the lowest floor that are in direct contact with the soil. Its purpose is to prevent moisture from the ground from penetrating the floor.
When following standard procedures, a technical plan must be prepared by the builder. This is usually done by the architect or a specialized planner. A missing technical plan for the waterproofing work constitutes a planning defect. If the building is located on a slope, additional waterproofing measures may be required around the walls.
The waterproofing membrane is installed directly on the concrete floor slab. This protects all subsequent construction elements from moisture. Installing it on top of insulation material is not professional practice.
When installing, be sure to ensure a proper connection to the wall, etc. This is usually done with special system edge strips. Simply extending the membrane up the wall does not constitute a professional wall connection!
Best regards
