Good morning everyone,

My driveway will be paved soon. Now I am wondering how the waterproofing (see red marking) between the garage screed and the future paving should be done.


Cross-section floor structure: concrete slab, cement screed separation layer, L-metal profile


What is the best way to seal this area?

Thank you in advance for your feedback.

First of all:
a garage is a secondary space. Therefore, waterproofing against rising damp is not necessarily required.
Unless there is a living space beneath the garage.
However, in the sketch (screed on separation layer without thermal insulation), this can be excluded (based on the information provided).
A drainage line connected to the house drainage system should be installed between the (paved) outdoor area and the garage floor connection. This is to prevent rainwater from entering the garage.
With this in place, the entire discussion about waterproofing (highlighted in red in the sketch) becomes irrelevant!
