What’s the difference between basement tanking and basement waterproofing?
17 July 2018
For most people a basement is just an old, musty storage space for your office where the Christmas tree, stationary or archived files live, however, there is a lot more potential to an unused basement than this. When our customers look to convert their basement into further commercial space they often ask the question “what is the difference between tanking and waterproofing?”
What BS8102:2009 recommends
BS 8102:2009 is the code of practice adhered to by Waterproofing Design Specialists for the protection of below ground structures against water from the ground.
What is Tanking?
Basement tanking uses a “barrier” to keep water out of the property. By applying an appropriate waterproofing barrier to the walls, the base slab and, where relevant, the roof of a below-ground structure, so that the entire envelope of the structure below ground is protected against water ingress.
What is Waterproofing?
Waterproofing describes materials and methods used to protect a structure from water ingress that might also provide resistance to the diffusion of water vapour. However, a cavity drain membrane is not considered to constitute a tanking system.
Type B: Structurally Integral Protection (usually to the relevant British Standard and of reinforced concrete structure) (BS 8007 and BS 8110)
Type C: Drained Protection (cavity drain membranes and construction drained cavities)
