Waterproofing Wisdom – Episode 02

Waterproofing Wisdom is our monthly snippet of thoughts/lessons learned/news. You can sign up here.

Intro

This is my second ever monthly email sharing “Waterproofing Wisdom”.

This episode will be most relevant to basement waterproofing specialists, but I think it is relevant to any construction professionals with basement projects due to start in the near future.

You can watch a 4/5 min video here or read the highlights below.

Waterproofing Wisdom

  1. The scope of BS 8102:2022 is broader and the guidance is (~30%) more extensive. This means that we ought to be even more cautious than we used to be about contracts which cite “in accordance with BS 8102” in the scope of work.
  2. The Grades of waterproofing performance (Table 2) have been changed. This means we will have a period of transition and possibly some confusion around Grade 1b and Grade 2. We will specifically add “in accordance with BS 8102:2022 table 2” after every mention of Grade for the next 5 years. We will also seek to more clearly define the boundaries between the grades and hope that consensus within the industry is quickly reached.
  3. The requirement to consider crack width calculations when specifying Type B concrete is now very clear. “Just add a waterproofing admixture” is no longer a justifiable approach and likely to be considered negligent.

You can download a copy of our 5 page document outlining What’s new with 8102 here.

Please also be aware of an imminent webinar on this same subject hosted by the Property Care Association. You can see more details here.

What would you like to hear about?

1. We’re working on some content to do with our design development process. This addresses issues such as “What is ‘design development’, as opposed to ‘abortive work’?” This content would be relevant to project managers, developers, architects, engineers and waterproofing specialists.

2. We could talk through BS 8102:2022 table 2 and attempt to share our take on the various grades. This would probably be more relevant to waterproofing specialists? #waterproofinggeek
