Hello,
I would like to install the dimpled membrane (dimpled membrane + fleece + foil) myself. However, I still have a few questions.
1. How do I attach the dimpled membrane to my basement wall (precast basement + perimeter insulation)?
I have received conflicting information. Some say the membrane must be fixed with bituminous adhesive, while others say it is sufficient to secure it with nails and vertical wooden battens.
2. The dimpled membrane I can get has a width of 2 meters (6.6 feet), and our basement walls are about 2.75 meters (9 feet) high. How should the membrane be installed in this case? Here, too, I have heard different advice from building center experts.
Some told me that the membrane must be installed like individual wallpaper strips—vertically. Others say it should be applied horizontally over the insulation. Since the basement height is about 2.75 meters (9 feet) and the membrane is only 2 meters (6.6 feet) wide, an additional strip must be placed above. Should the dimpled membrane be installed with an overlap in this case?
Thank you very much.

Hello, your stud is probably already finished... But since it’s really just a backfill protection, don’t worry too much. Experts recommend placing the studs facing outward, because during backfilling and compaction, the studs might press into the perimeter insulation and during further ground movements, could shift the insulation as well... Sounds plausible. I would run them horizontally, fix them only occasionally (using 20mm (¾ inch) cap nails into the insulation), and then backfill. A 15cm (6 inch) overlap is sufficient, or if you split a sheet in the middle at 2.75m (9 ft), you get a 25cm (10 inch) overlap.
