BS 8102:2022: some lesser known details explained


BS 8102:2022 for waterproofing isn’t just about the technical install anymore; it’s about the long-term legacy of the project. A few of the lesser known details are worth explaining.

  • A suitably qualified person must lead the waterproofing design.
  • Water pressure must be designed to the full retained height of the structure, not just what’s apparent when a water table is measured.
  • A design philosophy document is expected.

No document, no design.

  • For any Type C (cavity drainage) water management system, a formal maintenance schedule is now a mandatory requirement, and a critical document as part of the handover process.
  • BS 8102:2022 now clarifies previous confusion over Grade 2 and Grade 3 internal environments, such as damp areas and condensation, and active environmental controls such as ventilation, dehumidification or air conditioning.
