No drainage tile or pipe with a PWF (Preserved Wood Foundation) ⁉️

[mtnengineer]

What is the reasoning behind not using drainage tile (weeping tile) or pipe in a PWF

We're going to need more to go on than that.

I don't have a copy of the Alberta Building Code, but there is nothing exempting a wood foundation from the drainage section of the code in the NBC.

Are you asking why someone might not install a foundation drainage system with a wood foundation?

 

[Plumb-bob]

BC code requires foundation drainage "unless it can be shown to be unnecessary" ....

And there are 2 ways to achieve this- drainage pipes, or a granular layer.

For discussion: our office generally exempts drainage for situations where the space on both sides of a frost wall is infilled.

a "drainage system" is required
IAM just wondering why not to use a Drainage Pipe (Weeping TILE)
i can't for the "life of me" see why
there may places where it specifically says NOT TO USE A DRAINAGE "PIPE" : /
