To comply with British Standard BS8102/2022 and Third-party warranty providers you need to appoint a CSSW qualified waterproofing specialist onto the design team before technical design (RIBA 4).

This new requirement does not mean take advice from a designer,  it does however mean the CSSW  expert must be a design team appointment. They must also have PI for the advice and design they provide that is available throughout project. From early design right through to the construction and completion of basement waterproofing.

They must have suitable experience and be able to advise on all systems and options as well as buildability, repairability, sequencing, protection, hazards and CDM. MacLennan work with many of the market leading engineering and architecture practices in the UK to design best practice, best value guaranteed basement waterproofing solutions.

How Does Basement Waterproofing Work?

Basement waterproofing aims to prevent damp and moisture that can build up in an improperly built structure, in this case a basement. BS8102 is a compliance guide which must be adhered to so that you can have peace of mind the project being worked on is successful. Basement waterproofing is achieved through the use of materials such as, but not limited to, lime plaster or polyurea spray. Wall cavitys are filled where possible to prevent openings for moisture to run through, application of waterproofing membranes also help achieve our goals. As a leading provider of waterproofing services, we have access to numerous products to achieve the results we need for the specific building we are working on.

It's important that your waterproofing solution is BS8102 compliant. Download the BS8102 Guidance for Compliance that our MD Ian MacLennan contributed towards.

Environmental Policy

MacLennan strive to source our materials from the most sustainable sources possible and participate in pioneering recycling schemes.
