French drain/footer drain Q
Not sure what it’s called in your area, but my question is about the perforated pipe that runs along the perimeter of the foundation. In my application the pipe will be on the outside of the foundation and will be taken well away from house. And that is my question, if I need one given my setup.
im in zone 4c, and have a crawlspace with poured concrete foundation that is only about 12” tall. The sill plate is not pretty much flush with grade, with the grade very very slightly sloping toward house, but it really is pretty close to flat. So what I will do is excavate about 6’ from house, outward, and slope that down and away from house until I run into a new retaining wall I’ll put in 6’ away from foundation. That’ll allow me to have the dirt well below my sill plate and I’ll be able to control the slope away from house as well.
This side of the house does have gutters as well. So my question is, is a footer drain a good idea in this case? Or is it a little bit much. I’ve had mixed reviews given my application. But the one solid thing anyone gave me besides just a feeling was that if my house has gutters over where I’m talking about then a footer drain isn’t necessary.
laat question, if I do decide to go with it, does anyone have a recommended detail they can share with me? A link or picture… I looked for some on the website but they weren’t opening for some reason.
im looking for one that shows exactly where the pipe goes, and what materials to use around it, fabric, rock, etc.
thanks for the help!
