BS 8102:2022 An overview of changes to basement waterproofing guidance

7 Apr 2023

The revision to BS 8102:2009 Code of practice for protection of below ground structures against water from the ground was published in March 2022. A key driver for the revision was the grades of performance for below ground spaces and these have been updated to focus on designing for the intended use of the space.

The revision gives further guidance on achieving robust and maintainable waterproofing solutions with more focus on the construction stage. This summary document was prepared by TBIC members and is intended to assist those using the updated standard by highlighting key changes on a section by section basis. Further guidance on using BS 8102:2022 will be published by The Basement Information Centre. This will include updates to the following publications: Basements: Waterproofing, Basements: Ground gases and structural waterproofing and The Concrete Centre publication Concrete Basements.
