A webinar digging down into the construction and design systems that produce watertight new-build basements and the associated risks.

This webinar is the third in our series and will explore the protection grades set out in BS 8102:2022 and the Type A, Type B and Type C waterproofing systems, with a focus on their application to new-build below-ground structures. Particular attention will be given to the distinction between externally applied waterproofing systems and structurally integral waterproofing approaches, and how these influence design, construction sequencing, inspection requirements and long-term performance.

It will also highlight the risks associated with the different construction systems, as well as best practice methods for ensuring a specific type or combined waterproofing system will offer robust watertight protection. 

Reasons to attend

By the end of this webinar, you will be able to:

  • Differentiate between Type A externally applied barrier protection, Type B structurally integral protection, Type C drained protection and combined protection approaches

  • Assess how best‑practice design, detailing, installation and maintenance strategies contribute to robust, long‑term watertight performance in basements

Intended for

  • Structural engineers and built‑environment professionals interested in the design, assessment, and construction of basements and foundations.

  • Structural engineers in broader practice who encounter below‑ground structures and wish to deepen their technical understanding.
