Hello!
There are many suggestions on how to apply a waterproofing layer in a basement with incoming ground moisture.
One option I've heard is to only waterproof in the shower and about 30 cm outside, as well as along all the angles between the floor, walls, and corners. Then you should leave the rest unsealed to allow for moisture migration.
We will be pouring a new floor with underfloor heating, and with proper drainage and insulation under the slab.
Does anyone know how one should/can do in a basement with incoming ground moisture?
Best regards,
Mats
