If it is a semi-fluid construction and träsyll, you should have plastic underneath. If you use sheet metal laying, choose the variant with EPDM strips underneath (not the one with foam).
Okay, it's träsyll. Considering whether to place a sylltätning between the plastic and the rule to accommodate the unevenness of the slab, but damn, the EPDM strip is expensive if you can't buy just a few meters individually. A roll costs about 800 SEK.
