ᐅ Is there a general guideline for the amount of bitumen coating to apply?

Hello everyone,

You can probably guess my question from the title.
Is there a guideline on how thick the bitumen coating on the outside of the insulation (pink insulation material) should be?
The basement is a watertight concrete structure (white tank).

Thanks for your help.

Depending on the load case, there are manufacturer specifications, usually 3-4 mm (0.12-0.16 inches).

The manufacturer of the coating will specify that. I would try to find out who it is and then inquire directly with them.

A quick look at the metal containers on the construction site should be enough...
