Hello everyone,
we built 10 years ago. The construction area is located in Mechernich in the Eifel. A few months ago, there were severe floods in this area. We were not affected by the direct flooding, but since the water apparently stood underground too long in front of the floor slab (no basement) due to the clayey soil, water eventually penetrated the screed through the window sills. The screed has now been dried. To be prepared for the next storm, we are currently having drains installed retroactively. Now to my question: does it make sense to additionally seal the insulation boards attached to the floor slab with bitumen and lay a dimpled membrane in front of it? Some pictures of the situation on site are attached.
Thanks in advance for your tips.
Regards
Björn
