ᐅ Proper Basement Waterproofing (Bitumen)

Hello,

I want to properly waterproof my basement, which is made of poured concrete. A friend gave me some bitumen torch-on membranes that he had left over from his own construction project.

He said it’s fine to simply torch these directly onto the concrete floor in the basement.

However, I still have some questions that weren’t answered:

1. Should the floor be primed before applying the membrane?
2. What are the advantages of bitumen torch-on membranes with aluminum? When are they typically used?
3. Should the membranes extend and overlap slightly up the walls, or is it sufficient to cover only the floor?

Thanks!

Anyone asking such basic questions should not attempt something as important as waterproofing by themselves.

I won’t provide any information on this, and that is for your own protection...

If you want to do it yourself, it's better to use something like a Katja Sprint ...

Start first by asking why he wants to waterproof the basement. Is it technically necessary?

I have clarified and completed it with the architect. Thanks for the help.

And the result was?
