You’ve heard of negative-side waterproofing. You’ve heard of positive-side waterproofing. So, what is “blindside” waterproofing? After reading this article, you can add ‘Blindside Waterproofing Authority’ to your LinkedIn profile in a New York minute. (Translation for our international readers: Really fast—like, Roadrunner fast.)
The long short? Blindside waterproofing is a category of positive-side waterproofing.
The difference? When you’re pouring a foundation in a dense urban area – think downtown Toronto, New York, London, or Rio de Janeiro – conventional waterproofing simply isn’t possible.
Your project workflow will look more like this:
- Deploy a soil retention system that holds back the soil so your foundation hole does not collapse.
- Install your drainage board before you pour your concrete.
- Fasten your membrane sheet goods waterproofing material to your drainage board.
- Pour your foundation.
