Foundation Drainage

to the original picture:

read on another site that someplaces are utilizing the footing drain as a method to mitigate radon - would that have anything to do with the vertical unperforated pipe?

This is what we have...Not sure where it came from.

(Add) R405.3 Above grade drainage. Above grade drainage systems, including but not limited to gutters and downspouts, roof drains, yard drains, etc. shall not be connected to the foundation drainage system of concrete, masonry or wood foundations.

1. The pipe should go around the entire foundation and should be level. If the ends of the pipe is higher than the rest of the pipe, the pipe will not empty out.
2. If possible, run ends of pipe out of ground so that water can readily run off. If not possible dig a pit at each pipe end and fill with stones, creating a dry well which will collect water which would otherwise go into your garage.
3. Is your house at a low point so that water from the surrounding area naturally runs toward it? If so you will need to create berms to direct water away from house.
4. You should pipe your downspouts away from the house so that the downspout water does not end up in your garage. I would suggest at least ten feet of solid pipe on each downspout.
5. If a block wall the outside should have been parged with concrete and coated with a black foundation coat
