Newton Waterproofing Systems (John Newton & Company)

Type A waterproofing is defined by British Standard 8102:2022 as “barrier protection” which is applied to either the internal or external surface of a structure in order to resist the pressure of water trying to enter the building. This CPD therefore presents and considers the most relevant points to consider in specifying and installing Type A waterproofing.

This includes: A review of the principles of the British Standard and what has changed in the new BS 8102:2022 version regarding Type A waterproofing; Principles of Type A membranes, from historic issues & failures to contemporary designs for Type A solutions; an introduction to both post-applied and pre-applied external membranes; internal Type A membranes; and the importance of good detailing and specialist application.
