The perforated drain line is run around the foundation next to the bottom of the footing. At least that’s what many construction drawings show.

What is a French drain and how does it work?

How do you dig a trench around a foundation?
Dig a trench around the perimeter of the foundation. The trench will need to be dug down to the footers of the foundation and be about 4′ wide. You will also need to dig a trench away from the foundation to either a percolation trench, dry well or to daylight if the slope of the land allows.
Should drain pipe holes face up or down?
They should be facing down. If the holes face up, then silt will eventually fill the pipe. Also, with the holes down, the drainage from the pipe begins at the lowest level (bottom) of the pipe instead of at the top of the pipe; a 4″ difference in water removal depth.
