Gas protection[edit]
Gas protection for buildings should consist of an impermeable gas membrane and also a layer where the gas will collect and be vented in a controlled manner.
Guidance for this in the UK can be found in CIRIA C665 [2] and also BS 8485 and Title 40 of the United States Code of Federal Regulations, parts 239 through 282. This subchapter, I, was initially promulgated in 1976 and is also known as the Resource Conservation and Recovery Act.
