CPD Seminars

Designers, architects, and specifiers are faced with ever-more challenging environments, particularly in preventing the ingress of radon gas into the internal structure of a building from ground-based sources.

Our latest CPD seminar discusses the current guidance document (BR211:2023) for designers, illustrating how this information provides guiding principles that are key influencers in achieving an appropriate internal environment, preventing the ingress of ground-based radon gas into a building.

Delivered by one of our experienced Technical Support Managers the seminar will cover:

• Exploring the Background of Radon Gas- understanding its serious health implications, sources, and level criteria.


• Regulation and Guidance - Gain an understanding of the regulations and latest guidance documents that are available to assist the designer. (BR211:2023)


• Radon Membranes and Systems - Understand the essential factors to consider when developing a resilient design for protecting structures from ground-based radon gas.


• Radon System Design - Familiarise yourself with the available options for selecting a radon gas protection system that can achieve the necessary internal environment in compliance with the latest regulations and guidance.

Our newly updated Guide to designing below ground waterproofing protection CPD discusses the implications of the recently updated BS 8102:2022 guidance. In particular how designers and specifiers are faced with evermore challenging environments, especially the protection of below ground structures against water ingress.

This seminar discusses the current regulations and guidance documents available to the designer and how this information provides the guiding principles which are key influencers for achieving an appropriate internal environment for the below ground structure. The seminar reviews Type A, B and C waterproofing protection systems to BS 8102:2022
