Within the British Standard BS 8102 (2022) Protection of below ground structures against water ingress it can be quite confusing as there are many acceptable options on what can be specified to provide a waterproofing solution when designing a new build project involving a below ground element.
Usually a basement, the focus is often on the type of membrane system to be used, leading on to the type of membrane (whether liquid applied or a sheet membrane type etc.) however what is often overlooked is the fact that the structure itself can be used to create a standard watertight concrete structure without the need for other membrane products. A bold statement maybe, but it can certainly be achieved using a superior quality concrete from a superior quality ready mix concrete supplier, a few small adjustments to the standard concrete mix design and with the addition of an active waterproof concrete admixture added at the concrete plant such at Triton TT Admix.
If concrete is modified and with the addition of an active crystalline waterproof admixture and it can be placed, compacted, and cured properly it will create a very solid and robust initial line of water defence that is permanently and actively protected by life long self-healing and this is acceptable under the latest British Standard BS812 (2022). Waterproof concrete alone however may not be sufficient to create a finished habitable space however, for environments listed as Grade 1a, 1b or Grade 2 within BS8102 (2022) usually designed for utility areas or perhaps car parking space, it can provide a simple, quick to install (you just pour the concrete as normal) and very cost-effective option.
