Why would I need a specialist waterproofing consultant.

It is a requirement of British Standards and a statutory requirement of the Building Safety act 2022 that you demonstrate competence and have a qualified waterproofing specialist in the design team before technical design stages RIBA 3/4 for all basement projects.

A suitably qualified waterproofing specialist should be involved to advise on the Golden thread of documented design decisions which are required to comply with British Standard BS8102/22. The Building Safety Act 2022 and Building Control requirements.

A suitably qualified specialist can also advise on Third party warranty provider requirements and for historical properties how to comply with the requirements of conservation officers.

Acting as consultants only we are independent of manufacturers and contractors. We can provide unbiased advice on the most suitable and robust waterproofing systems without any commercial pressure.

We can offer true value engineering without the risk of compromising the design.

We will advise on insurance and guarantees.

As design specialists with practical experience from thousands of installations we can ensure a completely integrated design between the Architect, client, engineer and contractor.

A good design will avoid this
